Protected Area Tourism in a Changing Climate: Will Visitation at US National Parks Warm Up or Overheat?

Climate change will affect not only natural and cultural resources within protected areas but also tourism and visitation patterns. The U.S. National Park Service systematically collects data regarding its 270+ million annual recreation visits, and therefore provides an opportunity to examine how human visitation may respond to climate change from the tropics to the polar regions. To assess the relationship between climate and park visitation, we evaluated historical monthly mean air temperature and visitation data (1979–2013) at 340 parks and projected potential future visitation (2041–2060) based on two warming-climate scenarios and two visitation-growth scenarios. For the entire park system a third-order polynomial temperature model explained 69% of the variation in historical visitation trends. Visitation generally increased with increasing average monthly temperature, but decreased strongly with temperatures > 25°C. Linear to polynomial monthly temperature models also explained historical visitation at individual parks (R² 0.12-0.99, mean = 0.79, median = 0.87). Future visitation at almost all parks (95%) may change based on historical temperature, historical visitation, and future temperature projections. Warming-mediated increases in potential visitation are projected for most months in most parks (67–77% of months; range across future scenarios), resulting in future increases in total annual visits across the park system (8–23%) and expansion of the visitation season at individual parks (13–31 days). Although very warm months at some parks may see decreases in future visitation, this potential change represents a relatively small proportion of visitation across the national park system. A changing climate is likely to have cascading and complex effects on protected area visitation, management, and local economies. Results suggest that protected areas and neighboring communities that develop adaptation strategies for these changes may be able to both capitalize on opportunities and minimize detriment related to changing visitation.     

功能约束条件下的钱江源国家公园体制试点区游憩利用适宜性评价研究

国家公园功能分区根据生态系统和文化资源的保护要求划定不同的区域,并通过对区域内活动开展的范围和强度进行管控,实现生态保护、游憩利用等目标。从功能约束条件出发,以钱江源国家公园体制试点区(简称"钱江源国家公园")为例,采用德尔菲法和层次分析法,选取自然游憩资源、景观美景度、人文游憩资源、游憩利用能力、生态环境承载力、社会条件等6个因子构建了国家公园游憩利用适宜性评价体系。运用GIS空间分析工具对其进行单因子分级评价和综合评价,定量评估了钱江源国家公园游憩利用的适宜性,并将其适宜性从低到高依次划分为I—IV的4个等级。结果表明,钱江源国家公园游憩利用适宜性4个等级的面积呈"橄榄"型分布格局。在游憩利用适宜性分析结果及国家公园功能分区管理要求的基础上,本文进一步将钱江源国家公园游憩利用划分为6大游憩利用类型,并提出不同游憩利用类型的主导服务功能与管理措施。研究结果可为国家公园功能分区管理和游憩利用提供规划与管理指导。     

Visits to national parks: Effects of park characteristics and spatial demand

Understanding the relationship between the number of visits to national parks and their characteristics is crucial for park planning and management. Visitation has a key role in existing national parks, but also in assessing the social and economic impacts of new parks. This study examined how the natural characteristics of a park, the recreation facilities and services inside a park and tourist services in surrounding communities, as well as the park's location in relation to the population, are associated with the number of visits. Regression modelling was used to analyse the visitation to thirty-five national parks in Finland. The results demonstrated that recreation opportunities, the number of biotopes, the provision of trails and the park's age increase the number of visits, while the park location in relation to the population only has a significant effect in southern Finland. The results imply the dual role of national parks as resource-based destinations if the natural characteristics are outstanding, but also as more user-oriented areas fulfilling recreation needs in the most populated parts of the country.

城市公园景感要素及其对不同人群公园活动方式的影响

景感生态学以可持续发展为目标,契合了新型城镇化和人居环境科学的思想,强调以人为本,关注人的感知与环境的关系,为理解城市景观与人群活动的关系提供了一个崭新的视角。基于景感生态学视角,对城市公园常见的景感要素进行归纳分类,探讨城市公园景感要素对不同人群活动的作用途径;然后选择厦门市滨海、滨湖、山体、老城区和文化等五类典型城市公园的代表作为研究对象,实证分析和比较五类公园景感要素组成和民众感知评价的差异,并以此尝试解释不同类型公园吸引不同人群（访客密度、访问时间）及其在公园活动方式上的差异。研究结果表明,公园景感要素通过多层次关联对人群活动产生作用,即景感要素作用影响人的感觉类型,产生多样景感效果,满足民众由愿景产生的需求,进而影响其活动意愿和方式;各景感要素综合作用,共同对公园活动产生影响;当公园景感要素承载的设计愿景与民众愿景产生共鸣,才能产生良好景感效果,促进游园人群活动热情;公园景感要素和人群活动的关系侧重体现暴露性的生态系统服务。该论文研究结果希望为深入研究城市公园服务人群机制拓展一个自然与人文融合的崭新视角,同时为城市公园设计和运营提供有效的科技支撑。     

钱江源国家公园游憩利用潜力评价

游憩是国家公园重要的生态系统文化服务功能,国家公园游憩利用潜力评价是生态保护和国民游憩福利协同提升的关键。提出了国家公园游憩利用评价指标体系,包括游憩资源价值、游憩景观质量、游憩生态环境、游憩利用条件、国家公园社区、游憩利用管理6个维度,并开展多方法融合的国家公园游憩利用潜力评价研究。结果显示:国家公园游憩利用可以从游憩资源价值、游憩景观质量、游憩生态环境、游憩利用条件、国家公园社区、游憩利用管理六个维度进行评价;钱江源国家公园游憩利用的I-IV级潜力区域面积占比分别为8.99%、29.68%、39.72%、21.61%。其中,潜力相对较高的III级和IV级区域呈带状和块状分布在钱江源大峡谷、齐溪水库、高田坑-库坑-回台山、大源头-大横古村落五个区域;潜力相对低的I级和II级区域主要分布在国家公园生态保育区以及何田乡、苏庄镇的传统农业种植区。国家公园游憩利用价值与游憩展示区有较强的关联性,生态保育和传统农业生产对游憩利用价值发挥表现出较大的空间限制。本文能为钱江源国家公园生态旅游适宜区建设提供理论支撑。     

美国州立公园体系的发展、特征与评估

美国州立公园与国家公园相比,更强调满足州内居民就近户外休闲游憩需求的功能,这使得其在美国整体公共户外休闲空间体系中占据特殊的位置。在中国第一次全面地研究了美国州立公园体系的发展、特征及与国家公园体系的关系,特别是以部分州为例研究了美国州立公园的分类、质量评估、可达性与空间分布评估等关键问题。研究认为,州立公园的意义在于既缓解了美国国家公园面临的巨大旅游游憩压力,也满足了大众户外休闲游憩的需求。这值得中国在目前构建国家公园与自然保护地体系的同时予以借鉴。最后基于中国的实际需求与挑战,探讨了在省域/区域层次加强构建地方公园、保护地和游憩地体系建设的必要性与途径。     

国家公园生态系统健康测度模型构建及黄山实证研究

国家公园是中国生态文明建设的重要制度实践,其生态系统健康的科学评估是国家公园分区管理、空间管制、生态保护的基础。国家公园生态系统具有特殊性和复合性,区别于城市、流域、湿地等生态系统,亟需建立一套适合国家公园生态系统的生态系统健康测度模型。基于国家公园生态系统的特殊性和生态系统健康概念的多维性,探讨了现有模型存在的问题和不足,从生态系统与人类活动交互的视角,建立了"VSR"(生态活力Vigor、服务能力Service、抗干扰力Resilience)国家公园生态系统健康测度模型。此外,将"VSR"模型应用到黄山国家公园生态系统健康的测度中,可视化了黄山国家公园生态系统健康的时空过程和格局,通过随机森林回归模型和增强回归树模型验证了"VSR"模型的有效性和稳定性。"VSR"国家公园生态系统健康测度模型有效量化了国家公园生态系统健康的时空差异性和时空动态性,为国家公园空间管制、生态保护等目标实施提供了科学支撑。     

转型中工业城市的公园绿地社会公平性研究——以东莞市东城街道为例

作为城市重要的生态空间,公园绿地为城市提供环境基础及景观保障,其资源的合理分配是社会公平的重要体现。提出公园绿地社会公平性新的内涵,即无论个体所处的人居环境条件如何,其获得的城市公园绿地质量应该平等。工业城市向服务型、创新型城市的转变是中国城镇发展的典型趋势,研究其公园绿地的社会公平性为城市更新改造与公共资源分配提供重要的科学依据。以东莞市东城街道为例,构建社会-经济-自然复合人居指标体系与公园质量评价体系,基于可达性模型与Pearson相关性系数对公平性进行测度。结果表明：由于区域更新强度及顺序不同,研究区的绿地布局存在不公平现象,居民享受的公园质量与小区的自然、经济要素具有一定的关联。转型中的工业城市高质量公园聚集于风景资源优越的高端居住区,其他公园质量普遍不佳。工业园区以及旧城区为公园服务盲区的主要聚集地。     

北京城市公园湿地休憩功能的利用及其社会人口学因素

城市公园湿地是城市重要的生态基础设施,是城市居民休闲游憩的重要场所,具有重要的生态、社会文化服务功能。以北京地区20个典型的公园湿地为研究对象,采用问卷调查方法,将定性指标和定量指标相结合,用统计学方法分析了休憩者对公园湿地的使用情况,并采用Logistic回归方法揭示了影响城市公园湿地利用的社会人口学因素。结果表明:(1)休憩者到访公园湿地的距离与使用频率密切相关,43.4%的休憩者到达公园湿地的行程时间<1 h,这其中34.1%的休憩者使用公园湿地的频率每年在12次以上;仅有17.4%的休憩者每年使用各公园湿地频率为12次以上,这其中85%到达各公园湿地的行程时间<1h;(2)影响休憩者对公园湿地使用频率为每年12次以上的因素依次为行程时间、个人月收入、有无私家车、文化程度、职业、年龄。另外,性别与年龄的交互作用也有一定的影响;(3)愉悦身心是休憩者使用各公园湿地的最主要原因。研究旨在为城市公园湿地的合理优化与配置、城市绿地系统规划及城市的可持续发展提供科学依据。     

Functional diversity of urban bird communities: effects of landscape composition,green space area and vegetation cover

In this study, we aim to gain a better insight on how habitat filtering due to urbanization shapes bird communities of Vienna city parks. This may help to derive implications for urban planning in order to promote and maintain high diversity and ecosystem function in an increasing urbanized environment. The structure of wintering bird communities of 36 Vienna city parks – surveyed once a month in January 2009, December 2009, December 2012, and January 2013 – was described by species richness and the functional diversity measurements FRic (functional richness), FEve (functional evenness), and FDiv (functional divergence). Environmental filtering was quantified by park size, canopy heterogeneity within the park, and the proportion of sealed area surrounding each park. Species richness, FRic, and FDiv increased with increasing park size. Sealed area had a strong negative effect on species richness and FDiv. Canopy heterogeneity played a minor role in explaining variance in FDiv data. FEve did not respond to any of these park parameters. Our results suggest a loss of species richness and functional diversity, hence most likely indicate a decline in ecosystem function, with decreasing park size and increasing sealed area of the surrounding urban landscape matrix.     

Recreational Use of the Countryside: No Evidence that High Nature Value Enhances a Key Ecosystem Service

In Western Europe, recreational amenity is presented as an important cultural ecosystem service that, along with other values, helps justify policies to conserve biodiversity. However, whether recreational use by the public is enhanced at protected areas designated for nature conservation is unknown. This is the first study to model outdoor recreation at a national scale, examining habitat preferences with statutory designation (Site of Special Scientific Interest) as an indicator of nature conservation importance. Models were based on a massive, three year national household survey providing spatially-referenced recreational visits to the natural environment. Site characteristics including land cover were compared between these observed visit sites (n = 31,502) and randomly chosen control sites (n = 63,000). Recreationists preferred areas of coast, freshwater, broadleaved woodland and higher densities of footpaths and avoided arable, coniferous woodland and lowland heath. Although conservation designation offers similar or greater public access than undesignated areas of the same habitat, statutory designation decreased the probability of visitation to coastal and freshwater sites and gave no effect for broadleaved woodland. Thus general recreational use by the public did not represent an important ecosystem service of protected high-nature-value areas, so that intrinsic and existence values remain as the primary justifications for conservation of high nature value areas. Management of ‘green infrastructure’ sites of lower conservation value that offer desirable habitats and enhanced provision of footpaths, could mitigate recreational impacts on nearby valuable conservation areas.     

北京城市公园湿地的休憩吸引力评价

以北京地区20个城市公园湿地为研究对象,从公园湿地的景观质量、区位条件、可达性3方面构建了城市公园湿地休憩吸引力评价指标体系,并基于层次分析法赋权的综合指数评价方法,对公园湿地的休憩吸引力进行评价,最后通过实地问卷调查数据对休憩吸引力评价结果进行验证,结果表明:具有高休憩吸引力的公园湿地依次为颐和园、奥林匹克公园、青龙湖公园、北海公园、圆明园、玉渊潭公园、十渡、金海湖风景区、陶然亭公园、野鸭湖湿地,稻香湖湿地和珍珠湖风景区的休憩吸引力最低,其余8个公园湿地休憩吸引力一般.休憩吸引力评价结果与实际调查数据相符,说明所建立的评价指标体系与评价方法是可行的.20个公园湿地按照其休憩吸引力可聚为4类,据此可制定不同的管理对策.通过城市公园湿地休憩吸引力评价,分析城市公园湿地景观在休闲游憩方面所发挥的作用,可以为城市湿地公园的优化与配置、提高人居环境质量、改善城市景观布局提供依据.     

基于SolVES模型的关中-天水经济区生态系统文化服务评估

随着人类对于生态系统服务的需求持续增加,生态系统服务的评估逐渐成为研究热点。其中文化服务因其自身的无形性常在研究中被忽视且难以衡量。选取关中-天水经济区为研究区域,应用Sol VES模型并生成5种价值指数地图和价值总和地图来评估该区域生态系统的文化服务。结果表明:审美价值在秦岭山脉和城市公园等区域较高;娱乐价值在娱乐机会较多、交通便利的城市和秦岭北麓区域更高;文化与历史价值集中在历史文化底蕴深厚的城市地区;精神价值在与城市距离较近、有山川分布的森林公园更高。Sol VES模型在大范围区域的应用取得了较好的效果同时为政府进行生态建设和规划提供了科学依据。     

面向国家公园管理目标的综合灾害风险管理:一个概念模型

减小阻碍国家公园管理目标实现的灾害风险,实现管理有效性,是保证国家公园体制建设建立的重要途径。研究提出,面向国家公园多元管理目标,保障社会-生态系统稳定性和恢复力,国家公园灾害风险管理具有综合性。这种综合性体现在国家公园内致灾因子与承灾体的多样性、相对性与转化性,需要集成分别侧重社会与生态系统的传统自然灾害风险管理与生态风险管理,让灾害风险管理贯穿国家公园具体管理。为实现集成应对这种综合性,研究首先总结国内外多类型自然保护地灾害风险管理特点与经验,辨析国家公园灾害风险管理在国家公园管理职责和管理规划中的定位,从3个方面提出对我国国家公园灾害风险管理的启示：1）需要与国家公园宏观管理目标紧密相连;2）以维持社会-生态系统理想状态为目标;3）要具有管理空间、时间与运行的整体性。在此基础上提出一个面向国家公园管理目标的综合灾害风险管理框架,其主要特点是：1）具有"层级式"管理目标;2）以社会-生态系统服务为评价终点开展以理想状态为目标的风险管理;3）联结研究与管理、协调科学与价值观进行适应性管理。     

Shape Up or Ship Out: Can We Enhance Productivity in Coastal Aquaculture to Compete with Other Uses?

Coastal resources are coming under increasing pressure from competition between recreational, commercial and conservation uses. This is particularly so in coastal areas adjacent to major population centres. Given high recreational and conservation values in such areas, economic activities need to be highly efficient in order to persist. Management of these industries must therefore also encourage efficient production and full utilisation of the areas available. In order to achieve this, managers must first understand the level and drivers of productivity, and how these can be influenced. In this study, by way of illustration, the focus was on the Sydney rock oyster industry within Queensland''s Moreton Bay, a multiple use marine park with high recreational and conservation value adjacent to Australia’s third largest city. Productivity of the oyster industry in Moreton Bay is currently low compared to historic levels, and management has an objective of reversing this trend. It is unclear whether this difference is due to oyster farmers’ business choices and personal characteristics or whether varying environmental conditions in the Moreton Bay limit the capacity of the oyster industry. These require different management responses in order to enhance productivity. The study examined different productivity measures of the oyster industry using data envelopment analysis (DEA) to determine where productivity gains can be made and by how much. The findings suggest that the industry is operating at a high level of capacity utilisation, but a low level of efficiency. The results also suggest that both demographic and environmental conditions affect technical efficiency in the Bay, with water characteristics improvements and appropriate training potentially providing the greatest benefits to the industry. Methods used in this study are transferable to other industries and provide a means by which coastal aquaculture may be managed to ensure it remains competitive with other uses of coastal resources.     

景感生态学在城市生态系统服务中的应用研究——以城市公园景观设计为例

城市生态系统服务和可持续发展是当前城市生态学研究的热点问题。景感生态学作为联系生态系统服务和可持续发展的桥梁,可作为研究城市生态系服务和可持续发展的一种有效途径。随着社会发展所伴随的人们经济生活的生活压力增大,城市居民的亚健康状态日益突出。城市公园作为城市生态系统的重要构成,其设计目的应考虑应对城市居民健康问题和促进人类精神文明建设方面的作用。以城市公园景观设计为例,从园路、建筑、植物、水体景观和小品等方面探讨景感生态学在城市公园景观设计中的应用价值。景感生态学作为探索城市公园景观设计的新思路,以实现生态效益和居民福祉的提升,丰富和提升城市公园的生态系统服务功能,从而有利于促进为人类当代和后代提供可持续的福祉,以期驱使人类行为和言行规律朝着对生态系统有益的方向演化,自觉维护和改善生态系统服务,从而可持续地保障城市生态系统服务。     

生态系统休闲游憩价值评估——以北京密云区为例

作为生态产品总值核算的重要内容,生态系统文化服务主要包括休闲游憩、旅游康养与景观增值三个核算内容,但受公共产品性质的影响,休闲游憩服务缺乏市场价值,因此目前的研究很少涉及对生态系统休闲游憩价值的评估。而随着公园绿地等区域被广泛利用,其能为人们带来的休闲游憩服务也逐渐成为生态系统文化服务中不可忽视的重要组成部分。因此以北京密云区的公园绿地、滨水带与山地健身区为研究对象,运用替代成本法与支付意愿法对生态系统的休闲游憩价值进行评估与比较。结果表明,替代成本法评估的结果相对更合理;公园绿地、滨水带与山地健身区的休闲游憩价值分别为2.93亿元、4.54亿元、2.78亿元;密云区生态系统的休闲游憩价值为10.25亿元,其中费用成本6.69亿元,时间成本3.56亿元。     

Effects of human disturbance on spatial and temporal feeding patterns of Blackbird Turdus merula in urban parks in Madrid,Spain

We studied how human presence in three urban parks in Madrid (Spain) might affect Blackbird densities by changing feeding behaviour patterns. Our specific purposes were: (a) to ascertain the effect of park visitors on Blackbird feeding behaviour; (b) to analyse the influence of human disturbance on foraging success; and (c) to determine how humans affect Blackbird spatial and temporal patterns of habitat use. Pedestrians were the main source of flushing responses in all sampled parks, followed by Magpies Pica pica and dogs accompanying visitors. Blackbird responses to visitors entailed more time being vigilant and moving away from people and less time searching for food (decreasing food intake), a response that remained constant in the three parks. The number of pedestrians was positively correlated with Blackbird distance to pathways and negatively correlated with distance to protective cover. The number of active birds decreased with increase in the number of pedestrians during the day. Blackbird density was negatively related to the number of visitors per park. Our results confirmed that human disturbance negatively affects Blackbird feeding strategies in urban parks, ultimately modifying spatial and temporal patterns of habitat selection and abundance. Since such responses could also affect densities of other urban species by the same process, we propose some management measures to decrease the levels of disturbance as well as to enhance the recreational use of urban parks.
