基于生态经济功能区划的玛纳斯河流域生态服务价值评价

利用遥感和GIS技术, 对玛纳斯河流域及不同生态经济功能区1958-2006年的土地利用变化进行了分析, 并借助Costanza评估模型探讨了研究区及不同生态经济功能区的生态服务价值变化特征.结果表明: 在1958-2006年期间, 流域生态服务价值从22 130.86×10⁶元下降到16 050.45×10⁶元, 净损失6 080.41×10⁶元.研究区各土地利用类型的生态服务价值系数接近于区域真实值, 结果可信.流域不同生态经济功能区的生态服务价值存在明显的时空变化; 基于不同生态经济功能区的生态经济特点和生态问题, 提出相应的生态恢复策略以提高流域总的生态服务价值, 对实现该区的可持续发展具有重要意义.

Assessing the Ecosystem Service Values in the Manas River Basin Based on Ecological and Economic Division

In this paper, based on the techniques of remote sensing and GIS, the variation of land use in the Manas River basin was analyzed for various ecological and economic sub-areas from 1958 to 2006. Also, the variation characteristics of ecosystem service values were investigated by using of the Costanza evaluation model. It is revealed that the ecosystem service values reduced from ￥22.13 billion RMB Yuan in 1958 to ￥16.05 billion RMB Yuan in 2006; with a net loss of ￥6.08 billion RMB Yuan in the basin. The ecosystem service value coefficient of each land use was close to regional actual value. Thus the research results are credible. Ecosystem services of various ecological and economic sub-areas existed obvious variations in temporal and spatial scales during the period of 1958-2006. Therefore, according to the ecological and economic characteristics and ecological problems in various ecological and economic sub-areas, ecological recovery strategies are proposed, which are vital to achieve sustainable development in the Manas River basin.
