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 ...

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 ...
