东北典型黑土区土地利用变化的生态服务价值研究——以巴彦县为例

本研究在GIS与RS技术的支持下,采用生态服务价值法对处于东北典型黑土范围的巴彦县1991-2006年土地利用变化引起的生态服务价值变化进行研究。研究表明:1991-2006年巴彦县的土地利用结构呈单一化发展趋势,在土地利用程度上其土地利用整体处于发展期;1991-2006年巴彦县的耕地、建设用地和水域呈增加趋势,其它地类则减少,其中耕地增幅最大,为5.79%,草地减幅最多,达23.19%;15年间巴彦县生态服务总价值减少9235.41万元,减幅为3.65%,主要原因是林地和草地面积的减少使得巴彦县的生态服务总价值减少。

Ecosystem Service Values Based on Land Use Change in Black Soil Region of Northeast China——A Case Study of Bayan County

According to GIS and RS technique , exercise the ecosystem service value method, take the Bayan County which lies the typical black soil region, the paper studies the ecosystem service values change which is begotten by land use change during 1991-2006. The results indicate that during 1991-2006, the land use structure of the Bayan County takes on simplified development trend, the whole circs of land use is in the development phase reviewing from land use degree. During 1991-2006, the cultivated land, the constructed land and the water area of the Bayan County takes on ascending trend and the another land type reduces, then the cultivated land increases the most fast at 5.79% and the meadow reduces the most fast at 23.19%. The overall ecosystem service values decreases to 9235.41 thousand yuan, reduce to 3.65% than 15 years ago. As a result of the woodland and the meadow decreasing, the overall ecosystem service values of the Bayan County decreases.
