摘　　要：为探明垣曲县两条主要河流亳清河和沇河水系岸带土地利用景观的时空变化格局及其生态服务价值,基于MapGIS 10遥感平台,选取垣曲县2007、2014年6月两期影像数据,设置了亳清河和沇河0-150、150-300、300-500m的岸线缓冲带,通过计算对比分析了7年间垣曲县水系带土地利用景观的时空格局变化,并估算了生态服务价值。结果表明,7年间亳清河和沇河均表现为耕地和未利用山地减少,建设用地增加,两河岸带的建设用地分别增加了638.0、295.4hm2;亳清河和沇河生态环境变化导致其生态服务价值分别降低了23.89%、18.78%。该结论可为半干旱气候区季节性河流水系的生态环境保护提供一定的决策依据。In order to explore the spatial and temporal variations of landscape pattern and ecological environment effect on Yuanqu county river system（Boqinghe River and Yanhe River）,this paper used the data which collected from June 2007 and June 2014 to set up the shoreline buffer zones of 0-150 m,150-300 m,300-500 min Boqinghe River and Yanhe River in Yuncheng based on the MapGIS 10 remote sensing.The temporal and spatial variations of land use in 7years in Yuanqu county river system were analyzed and the value of ecosystem services was estimated.The results show that in 7years,the agricultural acreage and the untapped area of mountain of Boqinghe River and Yanhe River decreased while the acreage of construction land increased 638hm2 and 295.4hm2,respectively;however,the value of ecological service for Boqinghe River and Yanhe River decreased 23.89% and 18.78% because of the variations of ecological environment.The results can provide decision-making basis for the ecological environment protection of seasonal river system in semi-arid climate zone.
