耦合生态系统服务供求关系的生态安全格局动态分析——以闽三角城市群为例 [PDF]
, 2018 实现分区管理是缓解城市群生态安全空间差异的有利途径。基于供求理论构建了生态系统服务供求关系动态模型框架,并利用供给与需求的象限区划表征闽三角城市群生态安全格局;在不同的尺度变换上,运用价值单量修正模型、INVEST生境质量模型、景观指数模型、生态韧性模型、熵权法等方法综合测度城市群生态系统服务供求水平,实现生态安全格局的分区化;引入环境库兹涅茨曲线理论解析区域生态安全格局现状和成因;数据分析借助Arc GIS可视化表示。研究发现:(1)闽三角城市群存在50%区域属于生态安全高供给失衡区,其中70 ...

Evaluation of Aquatic Ecosystem Services in the Jiulong River Watershed [PDF]
, 2013 随着全球气候变化和人类活动干扰加剧，河流湖库化、水体污染和富营养化等流域性问题日益突出，这些问题已严重影响到流域生态系统服务和区域经济社会可持续发展。开展流域尺度的生态系统服务价值评估，有助于深入认识流域水生态、水环境动态变化及其驱动机制，同时为流域水污染削减方案优化、流域生态补偿等方面提供科学依据。对流域生态系统服务价值进行空间维度分析，可以为流域水环境综合管理提供更有针对性的政策制定依据。 本文在分析流域生态系统服务内涵，理清流域生态系统服务与流域水环境综合管理逻辑联系的基础上，提出基于GIS ...

Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

Integrative Conservation, Volume 4, Issue 3, Page 393-404, September 2025.We studied the challenges in human‐wildlife coexistence in Abohar wildlife sanctuary and the surrounding landscape in Punjab, India. We found that the local people's unique intrinsic motivation for conservation and the traditional approaches to conservation are no longer sufficient.

基于InVEST模型的渭河流域干支流生态系统服务时空演变特征分析
Shuitu Baochi Xuebao, 2021 渭河作为黄河的最大支流，是生态保护建成区重点之一，对其生态系统服务研究有利于实现流域内高质量发展和生态保护之间的平衡关系，保持流域生态系统服务功能，促进流域生态系统恢复。基于InVEST模型分析渭河流域2000—2018年5期土地利用和干支流生态系统服务时空动态变化，采用相关性分析水源涵养、土壤保持和生物多样性之间的权衡和协同。结果表明：19年间，研究区土地利用情况主要以耕地、草地和林地为主，占总面积的95%以上。流域内水源涵养呈现"先上升后下降"趋势，平均栅格单元产水量542.9 mm ...

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)

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,
