乌苏-奎屯-独山子地区生态系统服务功能变化研究

Study on Ecosystem Service Value Change in Wusu-Kuitun-Dushanzi Region

在3S技术的支持下,以1990年和2005年的TM图像解译数据为基础,采用谢高地的评价方法分析了乌苏-奎屯-独山子地区景观类型与生态系统服务功能的变化特征,为研究该地区水土开发与生态环境演变提供了依据。结果表明,1990-2005年,乌苏-奎屯-独山子地区农田、灌木林地、城镇及工业用地、盐碱地、水域和未利用地面积增加,其他乔木林地、草地、冰川和沼泽面积均减少;区域生态系统服务功能从1990年的9 182.84×106元减少到2005年的8 627.96×106元,减少量为554.87×106元,减少率为6.04%。保护区域生态环境,恢复和提高区域生态系统服务功能是该区域生态环境建设的重要任务。

Based on 3S technology and interpreted data from the Landsat TM images in 1990 and 2005,This paper analyzes the change characters of landscape types and ecosystem service function in Wusu-Kuitun-Dushanzi region by using the estimate method of XIE Gao-di,which would provide the theory support for regional sustainable development research.The results show that the area of farmland,cultivated land,shrub land,kaline soil,water body,unused land increased and other categories area including forest,grassland,glacier and marsh decreased from 1990 to 2005.The total ecosystem service values decreased slightly,from 9 182.84×106 Yuan to 8 627.96×106Yuan,and the regional total decreased quantities was 554.87×106 Yuan with a 6.04% net fall.So,it is important to protect regional ecological environment and improve the service function of regional ecosystem.
