清洁电力生产的生态效益评价方法研究 [PDF]

open access: yes全球能源互联网, 2021
清洁电力替代化石能源是应对全球气候变化的重要途径,不同电力生产方式的生态足迹差异会影响区域和全球生态系统服务。清洁电力生产的生态效益评价尽管很受重视,但是尚缺少一种定量方法。从电力生产基地直接和虚拟占地方面评价生态足迹,结合4种生态系统服务功能综合评价电力生产基地的生态影响,构建针对清洁电力生产的生态效益评价方法。基于全球能源互联网发展合作组织2050年全球清洁电力基地规划情况的研究发现:①水能、风能和光伏基地对土地利用的影响面积分别为52.9万、0.339万和1.94万 km2;②发展水电 ...

Priorities for protected area expansion so nations can meet their Kunming‐Montreal Global Biodiversity Framework commitments 甄选优先保护区域,确保各国履行昆明‐蒙特利尔全球生物多样性框架的承诺

open access: yesIntegrative Conservation, Volume 2, Issue 3, Page 140-155, September 2023., 2023
Here we provide a review of the type of areas that nations need to prioritise when implementing Target 3 that relates to area ‘quality’: areas of particular importance for biodiversity and ecosystem functions and services, are effectively conserved and managed through ecologically representative, well‐connected and equitably governed systems.

Identifying institutional configurations for policy outcomes: A comparison of ecosystem services delivery

open access: yesPolicy Studies Journal, Volume 51, Issue 3, Page 501-527, August 2023., 2023
Abstract This paper employs the Institutional Analysis and Development framework across six ecosystem delivery measures in the European Union to develop a configurational explanation of (un)successful outcomes. By undertaking comparative institutional analysis, we systematically examine the effect of variation across rule types and generate insights on

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Tropical and subtropical Asia's valued tree species under threat

open access: yesConservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Tree diversity in Asia's tropical and subtropical forests is central to nature‐based solutions. Species vulnerability to multiple threats, which affect provision of ecosystem services, is poorly understood. We conducted a region‐wide, spatially explicit assessment of the vulnerability of 63 socioeconomically important tree species to ...

Pollinator monitoring more than pays for itself

open access: yesJournal of Applied Ecology, Volume 58, Issue 1, Page 44-57, January 2021., 2021
We evaluated the full costs of running pollinator monitoring schemes against the economic benefits to research and society they provide. The annual costs of monitoring are <0.02% of the economic value of pollination services that would be lost after a 30% decline in pollination services.

Developing multiscale and integrative nature–people scenarios using the Nature Futures Framework

open access: yesPeople and Nature, Volume 2, Issue 4, Page 1172-1195, December 2020., 2020
Abstract Scientists have repeatedly argued that transformative, multiscale global scenarios are needed as tools in the quest to halt the decline of biodiversity and achieve sustainability goals. As a first step towards achieving this, the researchers who participated in the scenarios and models expert group of the Intergovernmental Science‐Policy ...

The handbook for standardized field and laboratory measurements in terrestrial climate change experiments and observational studies (ClimEx)

open access: yesMethods in Ecology and Evolution, Volume 11, Issue 1, Page 22-37, January 2020., 2020
Abstract Climate change is a world‐wide threat to biodiversity and ecosystem structure, functioning and services. To understand the underlying drivers and mechanisms, and to predict the consequences for nature and people, we urgently need better understanding of the direction and magnitude of climate change impacts across the soil–plant–atmosphere ...

武汉市土地利用与生态系统服务价值的时空变化分析

open access: yesShuitu Baochi Xuebao, 2006
生态系统服务价值的研究是目前生态学研究的热点之一。本文应用Costanza生态系统服务价值计算公式,采用谢高地等人的中国陆地生态系统单位面积生态服务价值表,分析了1988-2004年武汉市土地利用的时空变化,并计算由此导致的生态系统服务价值及其结构的时空变化,结果发现:①1988~2004年,武汉市土地利用变化的热点地区和总ESV变化的热点地区都主要集中在城郊区。②1988-2004年,武汉市总ESV增加了,但生态系统服务价值结构变化较大,生态系统提供某些单项服务的功能相对减弱。③1988-2004年 ...

重庆龙溪河流域水生态系统服务时空演变及对土地利用变化响应

open access: yesShuitu Baochi Xuebao, 2023
探究区域水生态系统服务时空变化状况及其与土地利用的关系,有利于区域水生态环境保护和国土资源合理开发利用,帮助决策者通过合理的土地利用方式提高区域生态系统服务能力,平衡区域生态功能与农业生产功能。选择位于长江上游重要生态屏障的重庆市龙溪河流域作为研究对象,利用InVEST模型,对龙溪河流域近20年产水、水质净化、土壤保持服务等水生态系统服务的时空变化特征和其受不同土地利用类型的影响进行了研究。结果表明:(1)近20年龙溪河流域水生态系统服务总体呈增强变好的趋势,但存在一定的空间差异性 ...
