Shuitu Baochi Xuebao, 2003 黄土高原在环境脆弱与经济发展低下的双重胁迫下，如何探索既适合环境保护又适应当地经济发展需求的战略对策至关重要。以黄土高原生态系统服务价值分析为基础，提出了该地区以农户单元、流域单元和区域尺度的生态系统服务恢复与重建对策。研究表明，尽管长期以来被人们所忽视，在生态环境脆弱区的生态系统服务价值依然是客观存在的，但是这些服务功能远不足以维持系统的自我循环，导致生态环境恶化趋势日趋严重。为此，必须科学分析该地区生态系统服务的现状与不足，并采取科学合理可行的生态系统恢复对策 ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Application of Landscape Ecological Redline Based on Ecosystem Services in China’s Coastal Reclamation Area [PDF]
, 2017 海岸带地处陆地和海洋两大系统的交互作用地带，其生态环境状态高度敏感和脆弱，特别是围填海活动这一高强度人类开发利用方式从根本上改变海岸带地区的自然属性，区域生态环境发生了深刻变化。 本研究定位于我国大陆沿海的围填海区域，通过人机交互目视解译的方法获取我国大陆沿海围填海区域的矢量数据，评估围填海活动对海岸带区域的景观类型和生态系统服务价值变化的影响，同时以围填海区域的生态系统服务评估结果为基础，识别我国海岸带的生态脆弱区和重要生态区，提出围填海区域景观生态红线的划定方法。本研究的主要内容和结论如下： (1)

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to

Dynamic Evolution of Regional Ecological Services Based on TM Remote Sensing [PDF]
, 2012 针对传统评估区域生态系统服务价值空间异质性的问题,本研究将TM遥感影像与价值评估法相结合,测算出针对研究区域的当量因子表,并建立了只需遥感影像数据即可快速并较为精准地动态计算区域生态系统服务价值的多元回归模型。文章以北京市永定河、厦门市和青海省不同尺度为例,对该方法评估区域生态系统服务价值的可行性和准确性进行了讨论,以期为生态综合管理提供定量化参考依据。This paper discussed the dynamic evaluating of regional ecological services ...

Servicesheds connect people to the landscapes upon which they depend
People and Nature, Volume 7, Issue 1, Page 112-126, January 2025.Abstract Ecosystem services (ES) are benefits people receive from nature. To sustain these benefits, we need to spatially connect communities benefitting from specific ES with landscape features that generate the ES. A variety of process‐based models support ES assessments by estimating the biophysical supply of ES that comes from landscapes.

Spatiotemporal dynamics of coastal ecosystem services using GIS and InVEST: a case study in the Longhai City [PDF]
, 2015 本文选取地处海西城市群的漳州龙海市为研究区,基于联合国千年评估提出的生态系统服务框架,借助gIS技术、In VEST模型和经济价值模型评估方法,评估龙海近30 A(1986~2010)生态系统服务价值时空动态变化。结果表明:从1986至2010年,龙海生态系统服务价值整体呈降低趋势,尤其在南溪河口区、卓岐镇海区、海门岛及漳州开发区更为明显;龙海研究区域内生态系统服务价值存在明显空间差异性,单位面积生态系统服务价值较高为卓岐镇海区、漳州开发区、隆教湾、海门岛,人类干扰强度最大的龙海市中心为最低 ...
