摘要
以山西省土地利用动态变化数据为基础,参照Costanza等人对全球生态系统服务价值的评价方法,对土地利用变化所引起的生态系统服务价值的动态变化和演变趋势进行分析。结果表明,与全国乃至全球相比,山西省生态系统服务价值严重不足,生态环境对经济增长的承载力很弱。由于人工生态系统居民点、工矿及交通用地的面积快速扩张,导致耕地面积下降,从而使得山西省生态系统服务价值从2000年的433.28亿元下降到2008年404.96亿元。生态系统服务价值预测结果还表明,山西省被破坏的生态环境到2020年仍难以恢复,且其经济发展与生态环境的矛盾将会更加突出。
Applying Constanzas ecosystem service value theory, this paper analyzes the of the ecosystem service value of Shanxi Province based on the data of dynamic change dynamic change of land use and. and evolution tendency The results show that during 2000 to 2008, the total value of ecosystem services in this province dropped from 433. 28 X 10^8yuan to 404. 96 ）〈 10^8yuan, ecosystem service value being inadequate compared with the whole country and the world, and that the carrying capacity of the ecologic environment was quite weak for economic growth. The results also indicate that the ruined ecologic environment of the province will not be renewed by 2020, and that the contradiction will be more serious between economic development and ecosystem environment.
