Research on the spatial and temporal variations and influencing factors of ecosystem service value in the Shaanxi-Gansu-Ningxia Revolutionary Region(陕甘宁革命老区生态系统服务价值时空分异及影响因素研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2022
陕甘宁革命老区是黄土高原和黄河中上游的重点生态治理区,作为重要的生态屏障区,其生态治理意义重大。以陕甘宁革命老区为研究区域,基于改进的生态系统服务价值(ecosystem service value,ESV)当量因子法,利用地理探测器及地理加权回归(geographically weighted regression,GWR)模型,分析1995—2018年各县ESV时空变化特征、影响因素及各主导因素作用强度的空间分异特征。结果表明:(1)1995—2018年,陕甘宁革命老区ESV呈先下降后上升的特征 ...

基于生态系统服务评价的围填海区域景观生态红线划分方法及应用研究 [PDF]

open access: yes, 2019
以围填海活动为代表的高强度的人类开发利用方式从根本上改变了海岸带地区的自然属性,区域生态环境发生了深刻变化。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,基于围填海活动影响下海岸带区域的景观类型和生态系统服务变化的评估结果,识别我国海岸带的生态脆弱区和重点保护区,提出围填海区域景观生态红线的划分方法。通过分析可知:(1)围填海区域景观生态红线区呈现出\"总体分散、局部集中\"的的分布特点;(2)景观生态红线区主要分布在人工湿地和残存自然湿地中 ...

生态承载力与生态系统生产总值耦合的生态系统服务评估—以福建省长汀县为例

open access: yesShuitu Baochi Xuebao, 2021
生态系统质量是区域探索生态优先、绿色发展为导向的高质量发展的重要基础。开展区域生态系统服务评估可获取国土空间生态本底特征,为生态系统保护格局构建提供现状底图,明确生态系统修复重点、国土空间优化提供导向。以长汀县为例,基于地区生态典型性、区域生物量差异及公众支付意愿与能力构建特色评价指标,采用生态承载力与生态系统生产总值耦合研究方法,对长汀县生态系统服务进行县域、镇域、村域及系统斑块等多尺度评估。结果表明:长汀县生态系统服务等级空间分布符合区划规律,大致呈中间低、四周高的特征;尺度细化使结果分布异质性更强,

Marine Ecological Damage Assessment and Compensation: Theory, Approaches and Case Studies [PDF]

open access: yes, 2015
海洋生态系统是地球生命支持系统之一,也是支撑人类生存和发展的重要资源宝库,对于人类经济的繁荣和生活质量的提高贡献巨大。然而,随着人类对海洋开发进程的加快,海洋环境与海洋生态系统面临着越来越大的压力,海洋资源利用冲突、海洋环境质量退化和生态破坏问题日益凸显。建立海洋生态损害补偿机制被认为是解决海洋资源利用冲突,保护海洋环境和生态系统永续发展的有效途径之一,而海洋生态损害补偿理论和方法的研究则是其重要的前提。目前,生态补偿的研究与实践多集中在陆域生态系统,涉海方面的研究尚不多见 ...
