摘　　要：利用遥感与GIS技术,对山西省汾河流域上游的宁武、静乐、岚县和娄烦等1990年至2010年的土地利用类型及其动态变化进行了研究,并分析其时空变化特征.结果表明,20a来汾河流域上游土地利用类型动态变化的主要特点是耕地明显减少,植被覆盖增加,建设用地显著增加,耕地面积主要流向植被覆盖和建设用地,汾河上游生态环境呈好转态势.Ecological environment on the present situation, spatial and temporal variation of land use in Ningwu,Jingle,Lanxian and Loufan from 1990 to 2010,which locate in the upstream watershed of Fenhe River,North Shanxi were studied by using RS and GIS,and the characteristics of the ecological environ- ment of this region were analyzed. The results showed that the main characteristics of the areas had a bet- ter situation that the cultivated lan^t area decreased significantly, and the vegetation coverage area increased small amplitude, construction land area increased obviously, the cultivated area mainly transferred into the vegetation Key words cover and land for construction.
