Research into the benefits that ecosystems contribute to human wellbeing has multiplied over the last few years following from the seminal contributions of the international Millennium Ecosystem Assessment. In comparison, the fact that some ecosystem goods and services undermine or harm human wellbeing has been seriously overlooked. These negative impacts have become known as ecosystem disservices. The neglect of ecosystem disservices is problematic because investments into the management or reduction of ecosystem disservices may yield better outcomes for human wellbeing, or at a lower investment, than management of ecosystem services. Additionally, management to optimise specific ecosystem services may simultaneously exacerbate associated disservices. We posit that one reason for the neglect of ecosystem disservices from the discourse and policy debates around ecosystems and human wellbeing is because there is no widely accepted definition or typology of ecosystem disservices. Here, we briefly examine current understandings of the term ecosystem disservices and offer a definition and a working typology to help generate debate, policy and management options around ecosystem disservices. We differentiate ecosystem disservices from natural hazards and social hazards, consider some of their inherent properties and then classify them into six categories. A variety of examples are used to illustrate the different types of, and management strategies to, ecosystem disservices.  相似文献

The promotion of sustainable cities is critical under future environmental change and population growth. Cities in the present and future can ensure the provision of ecosystem services to their urban inhabitants. The urban forest is one of the main suppliers of ecosystem services in urban areas, and can provide the base information to quantify ecosystem services and disservices, detecting the areas were low provision of those occur. In this study multiple ecosystem services and disservices were quantified using transferable indicators in order to detect areas for environmental improvement. The set of spatially explicit indicators enables the detection of areas of low and high provision of ecosystem services. The analysis showed synergies existing among regulating, provisioning and supporting services, while trade-offs were found with cultural services and regulating, provisioning and supporting services. Ecosystem services provision was positively related to the amount of vegetation and negatively related to its degree of fragmentation. A high provision of ecosystem services was found in less populated areas, with more educated and affluent people, highlighting the strong relations existing between social vulnerabilities and areas of low provision of services. Results from this research provide insights on the role of policy makers on better distributed supply of ecosystem services and on how the landscape structure can be modified to plan for sustainable cities.  相似文献

Urban areas have unique assemblages of species which are governed by novel ecological processes. People living in these environments have specific needs and demands in terms of ecosystem services (ES). Urban ecosystems are transformed in many ways by human activities and their floras comprise a high proportion of alien plant species, many of which were intentionally introduced to provide, augment or restore ES. Urban environments also have novel disturbance regimes and provide colonization sites for the establishment, dispersal and proliferation of alien plant species; such conditions often generate biological invasions which may cause marked changes to ES. We review the roles that alien plants play in providing urban ES and ecosystem disservices (EDS) globally. We identify the main ES and EDS associated with alien plants, and highlight the key species involved. A literature search revealed 335 papers, representing studies in 58 cities or urban areas in 27 countries. These studies recorded 337 alien plant species, contributing to 39 different ES and 27 EDS–310 species were recorded as contributing to ES and 53 species to EDS. A small number of alien plant taxa were frequently recorded as providing multiple ES in many urban ecosystems; the 10 most recorded species accounted for 21% of the ES recorded. Some of these species also result in significant EDS; three species accounted for 30% of the EDS recorded. Cultural services (notably aesthetics) are the most reported ES provided by alien plants in urban areas of developed countries, while provisioning services (notably food production) are most reported in developing countries. The most commonly studied EDS provided by alien plants is the impact on human health (notably allergic reactions). Eighty percent of studies on alien plants and ES and EDS have been done in developed countries. To elucidate the full range of effects of alien plants, more work is needed in developing countries. Urban planners and managers need to be mindful of both the positive and negative impacts of alien plant species to maximise the provision of ES.  相似文献

生态系统服务流研究进展   总被引:15,自引:6,他引:9  
王嘉丽  周伟奇 《生态学报》2019,39(12):4213-4222
生态系统服务流是实现生态系统服务供给与人类需求耦合的重要桥梁,是当前生态系统服务研究的热点与前沿。科学理解生态系统服务从产生、传递到使用的全过程,明确区域生态系统服务供给与需求的平衡状况,对于实现区域可持续发展与提高人类福祉具有重要意义。在综合分析国内外相关研究的基础上,阐述了生态系统服务流的概念内涵,归纳总结了生态系统服务流的定量研究方法,并系统梳理了国内外生态系统服务流研究在理论探索与应用案例方面的研究进展;探讨了当前生态系统服务流研究中存在的问题和不足,包括:生态系统服务从供给区传递至需求区的空间转移规律尚不明晰、定量评估生态系统服务流的方法不成熟、面向应用的生态系统服务流的研究较为缺乏,以及人与自然耦合系统中生态系统服务流研究框架有待进一步完善。未来的研究需要重点关注复杂系统中生态系统服务流跨尺度、跨区域的传递过程,加强生态系统服务的空间流动过程与传递路径的定量分析与模拟,重视生态系统服务流的应用性研究,尤其是在生态恢复、生态补偿、城市规划等方面的应用,并完善人与自然耦合系统中生态系统服务流的研究框架,以期促进生态系统服务流研究的发展。  相似文献

生态系统和景观是构成地球表层系统的基本功能单元。从对人类生存和发展支撑作用以及人类对环境合理利用和保护的角度,逐渐形成了生态系统服务和多功能景观的科学概念,相关的理论和应用研究也很快成为学术热点。但是从国内外主要进展上看,生态系统服务和景观多功能性的定量化研究都还比较薄弱。生态系统与景观具有等级关联性,前者是构成后者的基本要素,生态系统服务和景观功能具有同源性。因此,将生态系统服务与景观多功能性研究紧密结合既有现实基础又能够深化彼此研究的定量化水平,并进一步提出了生态系统服务与景观多功能性综合定量研究的整体性框架。从当前国内外研究文献看,该框架具有可行性,可以作为进一步深化生态系统服务和景观多功能性研究的现实途径。  相似文献

Natural ecosystems provide a variety of services on which humans, and other organisms, depend for survival and well-being. These ecosystem services can be categorized as provisioning (production of food, fiber, water and other resources), cultural (non-material benefits, such as recreation, spiritual and other aesthetic values), supporting (primary production, pollination, decomposition and soil formation necessary for resource production) and regulating (biological control and other feedback mechanisms that maintain relatively consistent delivery of services). Ecosystems also have been viewed as producing “disservices”, such as pests, litter, biological hazards such as diseases, animal attacks, allergenic and poisonous organisms, and geophysical hazards such as floods and storms. Many of these disservices are induced by management practices such as deforestation and concentration of agricultural crops. Insects affect ecosystem services in a variety of ways, positively and negatively. The papers in this special issue are focused on managing insects and ecosystems, and their interactions, in ways that ensure sustainability of ecosystem services and that minimize induction of disservices.  相似文献

Abstract Urban ecological studies have had a long history, but they have not been a component of mainstream ecology until recently. The growing interest of ecologists in urban systems provides an opportunity to articulate integrative frameworks, and identify research tools and approaches that can help achieve a broader ecological understanding of urban systems. Based on our experience in the Baltimore Ecosystem Study (BES), Long‐term Ecological Research project, located in metropolitan Baltimore, Maryland, USA, we identify several frameworks that may be useful in comparative urban studies, and may be worthy of consideration in other integrative urban ecosystem studies: (i) spatial patch dynamics of biophysical and social factors; (ii) the watershed as an integrative tool; and (iii) the human ecosystem framework. These frameworks build on empirical research investigating urban biota, nutrient and energy budgets, ecological footprints of cities, as well as biotic classifications aimed at urban planning. These frameworks bring together perspectives, measurements, and models from biophysical and social sciences. We illustrate their application in the BES, which is designed to investigate (i) the structure and change of the urban ecosystem; (ii) the fluxes of matter, energy, capital, and population in the metropolis; and (iii) how ecological information affects the quality of the local and regional environments. Exemplary results concerning urban stream nutrient flux, the ability of riparian zones to process nitrate pollution, and the lags in the relationships between vegetation structure and socio‐economic factors in specific neighbourhoods are presented. The current advances in urban ecological studies have profited greatly from the variety of integrative frameworks and tools that have been tested and applied in urban areas over the last decade. The field is poised to make significant progress as a result of ongoing conceptual and empirical consolidation.  相似文献

生态系统管理的一个重要挑战是在区域尺度上管理生态系统服务并提高当地居民福祉。以2009年土地利用数据和社会经济数据为基础,利用InVEST模型和空间制图在乡镇尺度上对密云水库上游流域水资源供给服务、土壤保持服务、水质净化服务、产品供给服务以及居民福祉进行了定量评估和空间特征刻画,并探讨了生态系统服务与居民福祉的不同关系模式。结果表明,流域内各乡镇土壤保持服务从上游到下游呈逐渐递增的趋势,水质净化服务从上游到下游整体上也呈逐渐递增的趋势,流域内水质净化服务功能与水资源供给服务、粮食供给服务、蔬菜供给服务以及畜牧产品供给服务在空间上呈显著负相关;基于生态系统服务与居民福祉在空间上的聚集特征,可将56个乡镇划分为低服务低福祉模式、供给服务依赖模式和高服务高福祉模式,针对这3种关系模式特点,可分别提出改善生态系统服务功能和居民福祉的管理措施。案例研究可为其他区域实施分区管理、协调生态系统服务功能保护与居民福祉的关系提供借鉴。  相似文献

人类福祉研究进展——基于可持续科学视角   总被引:5,自引:0,他引:5  
人类福祉的研究兴起于20世纪50年代。在过去的十几年中,人类福祉与生态系统服务一并成为可持续科学的核心概念,发展迅速。不同学科背景的研究者逐渐认识到仅仅依靠经济指标无法恰当地评估人类福祉,经济发展只是实现可持续发展目标的手段,而提高人类福祉才是其核心所在。人类福祉研究为评估个人福祉和国家社会的群体福祉提供概念框架和测量方法,服务于政府决策。自2005年联合国组织的《千年生态系统评估》报告明确提出生态系统服务与人类福祉的关系以来,人类福祉的研究进入了快速发展的新阶段。近年来,国内外越来越多的学者从可持续科学的视角对人类福祉开展研究。与国际同行的工作相比,我国人类福祉研究集中于可持续科学视角下对福祉的定量化评估,而各学科之间,尤其是自然科学和人文与社会科学之间的交流合作相对较少。回顾了人类福祉研究的历史发展,及其在可持续科学视角下的新进展,具体包括:客观福祉,主观福祉,生态系统服务与人类福祉关系。最后,讨论了人类福祉研究的主要议题,以及我国人类福祉研究未来的发展方向。  相似文献

The ecosystem service concept is becoming more and more acknowledged in science and decision-making, resulting in several applications in different case studies and in environmental management, but still it is developing in terms of definitions, typologies and understanding its complexity. By examining the interrelations between ecosystem properties, ecosystem integrity, biodiversity, ecosystem services and human well-being qualitatively, the mutual influences on each constituent of the ‘ecosystem service cascade’ are illuminated, giving an impulse for further discussions and improvements for a better understanding of the complexity of human–environmental systems. Results of the theoretical interactions are among others the assumption that provisioning services exclude or compete with each other, while the role of biodiversity was found to be supporting for regulating services and cultural services. Ecosystem services meet the criteria of being adequate human–environmental system indicators and therefore, they are an appropriate instrument for decision-making and management.  相似文献

城市景观格局演变的生态环境效应研究进展   总被引:27,自引:0,他引:27  
陈利顶  孙然好  刘海莲 《生态学报》2013,33(4):1042-1050
快速城市化过程剧烈影响着下垫面变化,直接带来了交通拥挤、资源短缺、环境污染、生态恶化等诸多问题,所有这些问题的出现均与景观格局演变密切相关,研究城市景观格局演变及其生态环境效应正在成为全社会关注的热点.系统总结了城市化过程对景观格局演变的影响,分析了城市景观格局演变的热环境效应、水环境效应、生态服务效应,以及城市生态用地与生态安全格局设计等方面的研究进展.指出了目前城市景观演变与生态环境效应研究中存在的问题与不足:(1)现有研究侧重于景观格局演变的量化分析和景观格局指数的计算,较少关注景观格局演变对生态环境及其区域生态安全的影响;(2)城市景观格局演变与热岛效应研究多局限于两者数理统计关系的分析,对于城市热环境形成的机理缺乏深入研究;(3)城市景观格局演变与大气环境效应方面更多研究关注绿地及其空间布局在吸收和降解大气污染物、固体颗粒物方面的作用,对城市景观格局演变的大气环境综合效应以及大气灰霾效应影响机理重视不够;(4)如何通过合理设置生态用地,有效提高城市生态服务功能和保障城市生态安全,目前仍缺乏深入而又系统的研究.下一步的研究中,需要综合多尺度的景观信息来揭示城市景观的演变机理和环境效应,构建基于城市空间扩展和生态服务效应评价的城市生态空间优化决策模型,探讨城市生态空间优化模式与安全格局.  相似文献
