Abstract:

基于土地利用图、统计年鉴及农户调研数据,分析宁夏固原市1995年和2005年食物供给、能源供给、水源涵养、就业供给与收入供给5大生态系统服务的空间格局及变化;通过分析人类对生态系统服务消费需求的满足程度,定量了研究区农民福祉及变化;结合土地利用变化数据,探讨生态保育对农民福祉的影响。结果表明从1995-2005年,固原市各县农民福祉有大幅提高,其中大多由于收入福祉与食物福祉的增加。整个固原市农民福祉的提高70.4%是来源于耕地生产力的增强,24.0%是由于生态保育。在生态保育对农民福祉的增加中,有26.9%是由于退耕还林还草对农民的补贴,70.5%是由于增强了当地的水源涵养功能。
