摘要: 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。

Abstract: In this paper, the effects of ecosystem conservation policy on material benefits of local residents in Guyuan City of Ningxia Hui Autonomous Region were studied. Patterns and variations of five ecosystem services under the ecosystem conservation policy were analyzed based on the land use data, statistic data and household survey data during the period from 1995 to 2005. The five ecosystem services were the food supply, energy supply, water conservation, job opportunities and income sources. Material benefits of local residents were quantified by comparing the ecosystem services with the human need and consumption to ecosystems. Integrated with the land use change data, the effects of ecosystem conservations on the material benefits of local residents were assessed. The results show that the material benefits of local residents in Guyuan City was increased significantly during the period from 1995 to 2005, especially the improvement of farmers' income and food supply. In detail, 70.4% increase of material benefits of local residents depended on the grain yield increase of arable land, and 24.0% was brought about the ecosystem conservation; 26.9% increase of material benefits of local residents came from the subsidies of the project of converting land for farming to forests (or grassplots), and 70.5% was brought about the improvement of water conservation capability.
