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 ...

Effects of Land Use Change on Imbalance in Ecosystem Services:A Case Study of Laizhou Bay Coastal Zone [PDF]
, 2016 以莱州湾海岸带为研究区,基于2000年、2005年、2010年和2014年多时相土地利用数据,应用生态系统服务价值评估,逐层剖析土地利用变化对生态系统服务失衡特征的影响。结果表明:莱州湾海岸带供水与空气组分调节服务呈负值,2000~2014年,生态系统服务总价值丧失43%(147亿美元/a),生态系统服务多样性降低甚至丧失,呈向海性,围填海造成162亿美元生态损失。土地利用变化方式是造成生态失衡的主因,主要包括:交通工矿、盐田、养殖及城镇扩张,滩涂、河口湿地、耕地被侵占。滩涂和河口湿地减少,导致废物处理、
