摘要:: 本文在GIS 与RS 技术的支持下，采用生态服务价值法对东北典型黑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：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；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 年间生态服务总价值减少，主要原因是林地和草地面积的减少使得生态服务总价值减少。

Abstract:: This research with the support of GIS and RS technology, by the method of ecological service value, the northeast typical changes of ecosystem service value caused by land use change were studied. Research shows that the diversified development trend of land use structure, and the land use in land use degree of the overall development; The cultivated land, construction land and waters in? creased, other class decreases, the cultivated land growth largest, at 5.79%, grass damped most, by 23.19%; 15 years ecological service value, the main reason is due to reduced woodland and grassland area ecosystem service value.
