丽香铁路建设对沿线景观格局影响的尺度效应及其生态风险

高原铁路作为大型廊道工程,线长点多、途经环境敏感,其对沿线生态环境影响评价范围的界定在环评工作实践中易产生争议.本文以丽香铁路唐布至建塘段为研究对象,利用2012年1∶10000土地利用现状图和数字高程模型为数据源,采用缓冲区与景观指数方法,构建了廊道切割度指数和廊道干扰累积作用指数,改进了衡量铁路建设后的生态风险指数.通过定量分析不同空间尺度下铁路建设前后景观格局时空变化特征和演变规律,得到本段铁路最适宜评价尺度,并在该尺度内对铁路建设前后生态风险时空变化特征进行分析.结果表明：廊道切割度指数有效反映出铁路廊道对各种景观类型的切割方式和程度,廊道干扰累积作用指数可衡量铁路风险源与风险受体之间暴露与危害关系;铁路建设后,铁路廊道将对沿线景观产生较大的正中切割作用,边缘切割和内部切割作用较小,林地和草地所受影响最大;景观格局指数在600 m缓冲区内尺度效应最明显,因此设置600 m为本段铁路最适宜生态影响评价范围;铁路建设前,600 m评价区以低生态风险为主,铁路建设后,生态风险显著增加,以中等以上生态风险区域为主;研究区生态风险具有南低北高,多核环形的分布特征.     

1985-2015年向海沼泽湿地斑块稳定性的空间变化

湿地稳定性对湿地生态系统的结构和功能起着至关重要的作用。为了研究湿地斑块稳定性的区域分异规律及时空动态变化,采用专家打分法,在斑块尺度上构建了湿地斑块稳定性模型,并以遥感影像为数据源,对1985-2015年的向海自然保护区及其周边地区沼泽湿地斑块稳定性的时空变化进行研究。结果表明：1985年与2015年的沼泽湿地斑块稳定性呈现中部最强、东部最弱、西部较强的特点;1985-2015年间研究区沼泽湿地斑块稳定性总体向东偏移,空间集聚性增强;1985-2015年研究区沼泽湿地斑块稳定性呈上升趋势,空间结构性变弱,离散程度增强;1985年沼泽湿地斑块稳定性由核心区向外逐渐递减,而2015年实验区的沼泽湿地斑块稳定性大于缓冲区。研究结果向海自然保护区及其周边地区沼泽湿地的规划与管理提供合理性建议。     

黄河口湿地生态网络构建与评价

构建生态网络能够有效连接破碎的生境, 对保护物种多样性具有重要意义。以黄河口为研究区域, 利用最小耗费距离模型和重力模型构建黄河口湿地“三横两竖”的生态网络框架, 并基于景观连通性指数法、廊道土地利用类型分析法和网络结构分析法对黄河口湿地生态网络进行了评价。研究结果表明: (1)通过构建生态网络, 生境源地的的IIC和PC分别提高到之前的4.5倍和8.6倍, 各生境源地的斑块重要性较为均衡。(2)不同生境源地之间相互关系密切程度随着距离和面积的变化存在差异。(3)黄河口湿地生态网络的α指数为0.4396, β指数为1.8125, γ指数为0.6304, 具有较大优化提升空间。(4)草本沼泽和灌丛湿地是生境源地主要景观组成, 盐沼湿地、草本沼泽和灌丛湿地是构成生态廊道的优势景观, 分别占生态网络景观组成的31.23%、23.86%和17.30%。黄河口湿地生态网络的构建对黄河口湿地生态保护和保护区规划有重要的参考价值。

以西溪国家湿地公园为研究案例,从景观功能分类入手,揭示城市湿地公园景观格局与功能特征。结果表明:(1)西溪湿地公园是以生态保护为主,兼顾合理利用为基本功能特征,其生态保护功能区面积占整个公园的53.7%,旅游休闲区面积占46.3%;(2)西溪湿地公园生态保护功能斑块在整个公园中所占面积为42.08%,且面积大、形状复杂、多样性较低;旅游休闲斑块面积占25.41%,并且表现为斑块面积小、形状规则、多样性高等特点;(3)西溪湿地公园生态保护廊道面积是旅游休闲廊道面积的一半左右,其网络结构比旅游休闲廊道复杂,有利于生态保护功能的发挥;(4)生态保护廊道缓冲区内主要由生态保护斑块组成,旅游休闲廊道的缓冲区内生态功能斑块和旅游休闲斑块所占面积相差不大。基于功能分类的景观格局研究方法有利于识别景观功能的空间特征,能够有效揭示景观生态保护与利用的空间关系。     

基于不可替代性的青海省三江源地区保护区功能区划研究

具有代表性、灵活性、综合性的保护区功能区划指标是决定区域划分合理与否的关键因素。不可替代性是近年来引入生物多样性保护规划的新概念,表达一个规划单元在实现整体保护目标中的重要性,能够反映生物多样性保护价值的空间分异规律,将其与人类活动干扰指数结合,可以在划分不同值域与功能分区之间建立联系。在系统保护规划框架下,首先根据三江源生物多样性特征确定了研究区域的指示物种和优先保护生态系统,然后结合物种生境特性,利用地理信息系统（GIS）技术进行了指示物种潜在分布范围预测,最后借助生物多样性保护规划软件（C-Plan）计算了三江源地区不可替代性指数,结合人类活动干扰进行了功能区划分,并对比了现有功能区划与新功能区划的贡献率。研究结果表明,不可替代性较高区域与原核心区空间分布基本一致（包括东部中铁、军功、麦秀森林灌丛区;西部索加、曲麻莱湖泊湿地区,高寒草甸区;北部扎陵湖、鄂陵湖、星星海湿地区;及南部玉树、囊谦森林灌丛区,当曲沼泽湿地区）;在保护区总面积未增加条件下,基于不可替代性的新功能区划较原功能区划的保护贡献率及保护效率有显著提高,核心区保护贡献率由61.20%增长到71.21%,新核心区 缓冲区总贡献率由77.57%增长到92.45%,保护区整体贡献率由91.20%增长到95.40%;从保护对象被保护情况看,新功能区划与原功能区划均能完全涵盖所有保护对象,但新功能区所包含的满足保护目标的保护对象明显增多,原功能区核心区,核心区 缓冲区,核心区 缓冲区 实验区完全实现目标的保护对象分别占27.50%,47.50%和80%,新功能区分别为32.50%,77.50%和87.50%（新功能区划下,只有苔草草甸、冰川雪山、湖泊3种生态系统类型和盘羊、黑颈鹤两个动物物种未达到保护目标）。在本研究基础上,讨论了该研究的意义、方法评价及现实问题,并提出三江源自然保护区功能区划调整建议：1）结合实际情况,基于不可替代性和人类活动的功能区划对现功能区划进行适当调整以增加保护区的保护贡献率;2）对于缓冲区中保护价值较高、人类活动干扰又较强的区域应进行严格的管理,制定完善的管理策略,避免因人类活动引起生物多样性丧失;3）鉴于当地经济发展需求,可以考虑在本研究确定的实验区及其外围开展水电站与矿产开发项目,但必须考虑开发项目对周围水域、植被及居民的影响。以期为三江源自然保护区功能区划的调整及资源开发提供参考,对三江源生物多样性的保护具有重要意义。

随着城市化进程的加快,东部发达区面临水土流失、生态廊道阻断、栖息地破碎化等生态问题。识别重要生态用地,构建生态安全格局,对区域生态保护和可持续发展具有重要意义。选取苏南地区为研究区,分别基于生物多样性保护价值、水资源安全和土壤保持3项指标进行生态用地识别,结合GIS技术进行生态用地评价,以高等级生态用地作为源地;利用最小累积阻力模型,识别缓冲区和生态廊道,构建区域生态安全格局。取得以下研究结果:(1)生态安全格局由源地、廊道和缓冲区共同构成。研究区内高等级(非常重要)生态用地面积比例为22.97%;将面积大于10 km~2的高等级生态用地提取为源地,生态源地的面积比例为19.17%。(2)基于最小累积阻力模型,确定了生态缓冲区和生态廊道,其中生态缓冲区占研究区总面积的30.52%,潜在生态廊道的主要景观构成为耕地、林地和水域,分别占廊道总面积的31.82%、19.06%和17.27%。(3)通过叠加城市建设用地与生态源地、生态缓冲区图层,识别城市建设用地与生态用地的冲突区域,总面积为603.84 km~2,占源地与缓冲区面积总和的4.38%,空间上主要集中在长江沿线和太湖周边。     

基于形态空间格局分析和最小累积阻力模型的广州市生态网络构建

构建生态网络对改善快速城市化背景下城市生态环境问题具有重要作用.本研究以广州市为研究区,采用形态学空间分析方法(MSPA)和景观指数法,提取景观连通性较好的核心区作为生态源地,并基于最小累积阻力模型(MCR)构建广州市生态廊道网络,通过重力模型和连通性指数定量分析生态网络结构,最后提出生态网络的优化对策.结果表明: 广州市共有10块核心区可作为生态源地,重要廊道有18条,一般廊道有27条,主要分布在研究区东北部;优化后的生态网络增加了5个生态源地和13条规划廊道,其结构指数有所改善;林地是生态廊道的主要组成景观,重要廊道的适宜宽度为60～100 m,规划廊道的适宜宽度为30～60 m.研究结果可为城市生态廊道规划提供科学参考.     

红松洼自然保护区草甸群落结构与多样性对管理模式的响应

管理模式对草甸植物群落结构和多样性有重要影响。以红松洼国家级自然保护区为研究地点,对比研究了实验区、缓冲区和核心区草甸植物群落结构和多样性对不同管理模式的响应。结果表明:实验区群落盖度显著高于核心区和缓冲区(P<0.05),三个区群落高度差异不显著(P>0.05),核心区群落密度明显高于实验区和缓冲区(P<0.05),三个区枯死物现存量差异显著(P<0.05);实验区地上生物量显著低于缓冲区和核心区(P<0.05),核心区地下生物量明显高于缓冲区和实验区(P<0.05);三个区的地下生物量都主要分布在0～10cm土层,向下逐层降低,其中核心区和实验区绝大部分根系主要分布在土壤表层,但相对深度不同;实验区与缓冲区植物群落优势物种较多,多个物种共同占有优势,而核心区的优势种少,优势物种集中;Shannon指数大小依次为缓冲区>实验区>核心区,Margalef指数为缓冲区>核心区>实验区。     

盐城海滨湿地景观演变关键土壤生态因子与阈值研究

文章以盐城海滨湿地典型区域为案例,以2011年4月和2012年4月对海滨湿地土壤数据为基础,结合2011年ETM 遥感影像,运用灰色关联分析、线性回归模拟和地统计学方法,辨识海滨湿地景观演变的关键生态因子,并确定其生态阈值。得出基本结论如下：(1)海滨湿地土壤理化性质海陆差异明显：从米草沼泽—碱蓬沼泽—芦苇沼泽,土壤水分和盐度表现出递减的趋势;土壤有机质、营养盐总体上从米草沼泽—碱蓬沼泽—芦苇沼泽,表现出两头高中间低的特征;湿润年份土壤水分高于干旱年份,湿润年份土壤盐度低于干旱年份。(2)灰色关联分析表明:干旱年份,水分＞盐度＞铵态氮＞速效钾＞有机质＞有效磷;湿润年份为：盐度＞水分＞有效磷＞铵态氮＞速效钾＞有机质,因此把土壤水分和盐度确定为海滨湿地景观演变的关键生态因子。(3)土壤水分和盐度在东西海陆方向上的变异大于南北海岸延伸方向上的变异。(4)将景观类型图和海滨湿地土壤水分与盐度分异图叠加分析,得出：芦苇滩土壤水分阈值＜42.332%,盐度阈值＜0.745%;碱蓬滩土壤水分阈值为38.836%～46.593%,盐度阈值为0.403%～1.314%;米草滩土壤水分阈值＞39.475%,盐度阈值＞0.403%;光滩的土壤阈值＞41.550%,盐度阈值＞0.656%。     

基于MSPA分析的福建省生态网络构建

快速城镇化进程导致森林景观破碎化、连通性下降,严重威胁区域可持续发展、生物多样性保护和生态服务能力的维持。生态网络构建是提高景观连接度,维持物种扩散过程,保护生物多样性的有效手段。以福建省为例,借助形态学空间格局分析(MSPA)探讨2000、2010和2020年的森林景观结构动态变化,并在利用组分数(NC)与整体连通性指数(IIC)确定适宜距离阈值的基础上,根据可能连通性指数(PC)筛选生态源地;从人-地关系角度选择路网分布、建设用地分布、土地覆盖类型、坡度四种评价因子构建阻力面,采用最小阻力模型(MCR)提取生态廊道形成初步生态网络,进一步计算PC指数对生态廊道进行重要性分级;最后基于图论法,利用闭合度α、线点率β、网络连接度γ对所构建的生态网络进行定量评价。结果表明：(1)近20年来福建省森林景观结构较为稳定,其中核心区占比高达76.27%,但仍存在一定程度的破碎化趋势;(2)根据NC与IIC的计算结果,以500m为合适的距离阈值计算了PC,据此识别出15处生态源地,多位于闽西及闽北地区;(3)采用MCR模型提取了105条生态廊道,其中重要生态廊道27条,分布均匀且连通四方;(4)...     

Oil pipeline corridor through an intact forest alters ground beetle (Coleoptera: Carabidae) assemblages in southeastern Ohio

Litter-dwelling ground beetle (Coleoptera: Carabidae) assemblages were monitored 1 yr after the construction of a corridor for installation of an oil pipeline along a xeric ridge-top forest in southeastern Ohio. After the creation of the corridor, three distinct habitats were evident in these sites: open corridor, ecotone areas around the corridor, and undisturbed forest interior. Carabidae were collected using directional pitfall traps that were placed parallel and perpendicular to the corridor in each of the three habitats. Results indicate that more carabids were present in the ecotone than in the other two habitats. Carabid diversity as estimated by rarefaction was highest in the corridor followed by ecotone and forest interior. Generalist and forest specialists such as Synuchus impunctatus (Say), Carabus goryi Dejean, and Pterostichus trinarius (Casey) were present in greater numbers in the forest interior and ecotone assemblages. In contrast, open-habitat specialists such as Harpalus pensylvanicus (DeGeer) and Selenophorus opalinus (LeConte) were present in greater numbers in the corridor assemblages. Carabid assemblages of the corridor were distinct from those of the ecotone and forest interior, whereas the latter two habitats had very similar assemblages. The successional pathway of the corridor carabid assemblage will therefore be likely different from that of the forest interior and ecotone. Overall, results indicate that construction of the oil pipeline corridor had significant short-term effects on the carabid numbers, diversity, and species composition because of ensuing habitat changes and fragmentation of the forest.     

A case study on the effects of a transmission-line corridor on Sika deer habitat use at the foothills of Mt Goyo,northern Honshu,Japan

Forage biomass and habitat use of Sika deer (Cervus nippon) at a transmission-line corridor were studied at the foothills of Mt Goyo, northern Japan. Summer forage biomass in the corridor was five times greater than in the adjacentBetula grossa forest. Among the plants that increased in the corridor,Sasa nipponica (a dwarf bamboo), an important forage plant for Sika deer, was predominant. Winter utilization ofS. nipponica by Sika deer was slightly heavier in the corridor, and estimated removal ofSasa leaves was twice as great there as in the forest. However fecal pellets were more prevalent in the adjacent forest in winter. Sika deer seemed to use the transmission-line corridor as a feeding site and the adjacent forest as cover as it reduces wind speed. A transmission-line corridor is more beneficial than a large clear-cut area because it provides more forest edges.     

The effects of local and landscape-scale habitat characteristics and prey availability on corridor use by carnivores: A comparison of two contrasting farmlands

Corridors are thought to reduce the negative biological effects of habitat loss and fragmentation by providing connectivity and suitable habitat for many species, including carnivores. Although corridor structure maintenance is considered to be an essential tool for carnivore conservation in a human-dominated landscape, surprisingly little is known about the effects of different factors at various spatial scales. The main aim of this study was to determine how local and landscape-scale habitat characteristics and prey availability influence the corridor use by carnivores in a Central European agricultural landscape. Moreover we investigated carnivore corridor occurrence in two contrasting landscapes that differ in level of habitat loss and fragmentation to evaluate relative effect of species-specific response to regional context. Results show that the availability of principal prey (small mammals) was the most crucial factor affecting carnivore corridor use. Other important factors influencing corridor use were corridor width (positive), proportion of shrubs (positive) and presence of local, low-traffic, roads (positive). Single species models revealed interspecific and area-specific differences in carnivore preference at both spatial scales. Our findings confirm the general importance of multi-level approach to evaluating species-specific habitat requirements as a crucial tool for determining suitable methods for carnivore efficient conservation in human-dominated agricultural landscape.     

River corridor plants revisited: What drives their unique distribution patterns?

The phenomenon whereby some plant species display a river corridor distribution pattern has long been recognized but is still poorly understood. The goals of this study were to supplement the list of river corridor plants for Central Europe, analyse their habitats and compare their ecological features with those of their widely distributed counterparts. The ATPOL (Atlas of Poland) database was used to compile a list of river corridor plants of Poland and calculate their river corridor-specificity indices (RCSIs). The Ellenberg indicator values, dispersal modes and life forms of river corridor and widely distributed species were compared using generalized linear mixed models (GLMMs). Eighty-five species were classified as river corridor species. The most numerous habitat groups were meadow species (19%), wet-habitat therophytes (15%), riverside tall herbs (13%) and species of dry, sandy soils (12%). These species had mostly requirements for a higher temperature and alkalinity than widespread species. Among river corridor plants, there were a few eurytopic species. Corridor species had usually only one life form and less dispersal modes than widespread species. Hence, specific demands of corridor plants and lower phenotypic plasticity may explain their restricted geographical distribution. The definition of the river corridor plant species needs modification.     

Monitoring the Chilla–Motichur wildlife corridor using geospatial tools

The present study attempts to assess the Chilla–Motichur wildlife corridor of Rajaji National Park in the Uttaranchal State of India using temporal satellite imagery from the years 1972, 1990, and 2005. The on-screen visual interpretation of three-period imagery followed by change matrix analysis revealed considerable corridor loss between 1972 and 2005 (17.56 km²). The loss was more pronounced between 1972 and 1990 (11.18 km²) than between 1990 and 2005 (6.38 km²). The loss of the corridor was attributed to various developmental projects, such as: roads; rail; hydropower canal; the expansion of townships of Hardwar and Rishikesh; the resettlement of people displaced by the construction of the Tehri dam; and creation of the army cantonment. This study highlights the conservation concerns relating to the depletion of the corridor with the passage of time. The study also demonstrated the unique potential of remote sensing and geographic information systems (GIS) in corridor status assessment and monitoring.     

The Effect of a Disturbance Corridor on an Ecological Reserve

The effect of a pipeline corridor constructed through an ecological reserve in Southern California was investigated by assessing plant species composition and soil chemistry. A homogeneous plant community comprised primarily of exotic annuals was found along the entire length of the corridor. This community has low similarity to the adjacent native plant communities. Soil organic matter was significantly less on the disturbed corridor than in contiguous undisturbed areas. Both available nitrogen and extractable phosphorus values were greater in the disturbed corridor. By contrast, total nitrogen was significantly higher outside the pipeline. The more labile litter of the exotic annuals allows increased mineralization along the corridor than does the more recalcitrant litter of the native perennial shrubs in the undisturbed areas. Once established, the weedy exotic annual litter may completely turn over organic matter and nitrogen, favoring the persistence of the weedy annuals. These exotic annuals appear to be moving into three of the native communities - grassland, coastal sage, and oak woodland - that have less organic matter and a more open plant canopy. Poor restoration efforts can lead to the establishment of such exotics, subsequent invasion into the surrounding undisturbed habitat, and degradation of the reserve.     

The impact of a utility corridor on terrestrial gastropod biodiversity

Utility corridors are often thought to be disruptive to biodiversity because they cause habitat fragmentation that may lead to increases in predation, parasitism, disease transmittance and vagrant species while decreasing migration rates, gene flow and genetic diversity for interior species. Species with poor dispersal abilities, sedentary lifestyles, and specialized habitats have been thought to be potentially the most vulnerable to these effects. Terrestrial gastropods thus serve as a valuable system in which to investigate these impacts because they are among the poorest active dispersers in the animal kingdom. To document the impact of corridor formation on land snail biodiversity, a 75-year old powerline right-of-way in the eastern Upper Peninsula of Michigan was chosen for analysis. While terrestrial gastropod richness and abundance was significantly reduced for corridor as compared to adjacent control subsamples, with a 2/3 turnover in species composition, the corridor fauna is similar to nearby native grassland sites in terms of species composition, abundance distribution, and numbers and abundance of species of conservation concern. The fauna of control subsamples immediately adjacent to the corridor remained similar to other undisturbed sites in the region, with multiple species of conservation concern persisting at distances of only 30 m from the corridor. Thus, the net impact of corridor generation has been arguably positive: while the surrounding forest fauna has not been degraded, within the corridor the reduction of forest species has been compensated for by establishment of even rarer grassland species.     

基于鸟类视角的城市生态廊道构建方法研究综述

基于鸟类移动特征与栖息地需求的生态廊道不仅有利于减少由生境丧失与生境破碎化导致的物种灭绝,进而促进物种的基因扩散与交流,而且可以改善城市居民的身心健康,推动城市不动产增值。然而,迄今为止,由国外学者研发的主要生态廊道构建方法没有内在地考虑鸟类的移动与生境特征,国内学者的鸟类生态廊道研究则侧重于对技术方法的探索而缺乏对研究鸟种特征的认知。因此,基于鸟类视角的城市生态廊道构建研究尚有较大的改进空间。本文通过对1975—2020年的国内外相关研究进行分析,识别出了可结合鸟类生态的7种廊道构建方法及3种廊道优化方法,并总结了相关方法的优缺点及其适用情况。最后,本文认为将典型鸟类物种的观测数据、真实运动能力与景观结构相融合,研发出计算高效便捷而且能够模拟廊道生态效益的计算机模型,将会是鸟类生态廊道构建方法的发展趋势。     

Monitoring movement into and through a newly planted rainforest corridor using genetic analysis of natal origin

Summary Genetic analysis of individual origins works best with populations that are genetically distinct but which exchange a high rate of immigrants, conditions that don’t normally coexist since immigration acts to prevent the accumulation of genetic differences. We provide empirical results from a newly constructed habitat linkage to illustrate the unique suitability of such analysis to monitoring the re‐establishment of connections between previously isolated populations. Donaghy’s Corridor links a previously isolated 498 ha fragment of rainforest to an adjacent 80 000 ha of intact forest. Starting in the final year of the planting programme that established the corridor, we trapped two species of native small mammals, the Bush Rat (Rattus fuscipes) and the Cape York Rat (Rattus leucopus), within and nearby the linkage. We used genetic data from ear clippings to determine which side of the corridor individual animals originated from, and by comparing this information to trap locations, we identified 16 long‐distance movements through the corridor. As genetic analysis of origins allowed movements to be detected from a single capture event and as it reflected movement since birth, this approach yielded considerably more data than capture records alone. The combination of movement and capture records allowed species‐specific assessment of corridor function, revealing that the use and occupation of the corridor was higher for Bush Rat than for Cape York Rat and was neither symmetrical nor uniform. Long‐distance movements through the corridor were most common immediately after habitat restoration, dropping off as the reconstructed habitat was colonized.     

厦门湾中华白海豚潜在生态廊道识别及人类活动干扰评估

生态廊道具有维持或恢复生态连通性的功能，对于连接生物栖息地、保护物种多样性具有重要意义。现有的生态廊道研究主要集中于陆地，而海洋生态系统具有水体广泛连通、缺乏直观的景观斑块等特点，导致海洋生态廊道的研究成为长期以来的科学难题。以栖息地位于厦门湾的国家一级保护动物中华白海豚（Sousa chinensis）为对象，尝试基于物种分布模型和最小成本路径分析法建立海洋生态廊道的识别方法。研究采用物种分布模型识别厦门湾内中华白海豚的适宜生境分布区和节点，并利用模型产出的生境适宜性结果生成海洋中的阻力表面，模拟计算节点与节点间在阻力表面上的最小成本路径，从而生成物种扩散网络。研究结果显示，厦门湾中华白海豚的分布主要受到航道距离、到岸线距离和叶绿素浓度三项因素的影响，主要适宜生境位于西海域至九龙江口和大嶝海域。潜在的核心生态廊道面积93.19km²，次级生态廊道面积170.41km²，九龙江口-鼓浪屿南侧-黄厝-大小嶝岛沿线可能是厦门湾中华白海豚的主要迁移路线。在此基础上，从用海空间重叠和桥梁影响两方面开展了人类活动对廊道的干扰评估。评估结果显示旅游活动和航运活动可能是中华白海豚生态廊道的主要影响来源，其中核心廊道受旅游活动影响更大，次级廊道受航运活动的影响更大。此外，厦门岛北部的桥梁亦可能会影响中华白海豚生态廊道的连通性。研究创新性地提出了海洋生态廊道的空间定量化识别方法并成功应用于厦门湾中华白海豚研究，研究结果可为我国海洋生物多样性保护、海洋保护区的空间规划等领域提供新的科学工具。
