摘　　要：文章以石羊河上游的土地利用/覆被变化状况为研究对象,应用Envi和Arcgis的技术对研究区1986年、2000年、2014年三期遥感影像进行土地利用/覆被变化信息解译的数据,采用土地利用/覆被变化单一动态度、土地利用/覆被程度综合指数及土地利用/覆被重心转移等方法,对石羊河上游近30年土地利用/覆被变化特征进行分析。结果表明:(1)在1986-2014年间林地和草地一直为研究区内的主导土地利用类型;(2)在1986-2014年间林地、草地、水域的面积变化都经历了先减少后增加的过程,而耕地则经历了先增加后减少的过程,其中水域的变化程度最剧烈;(3)在1986-2014年间,研究区土地利用/覆被程度综合指数变化较小,且1986-2000年土地利用/覆被处于发展期,2000-2014年间处于调整期。In this paper,the land use/cover change in the upper reaches of ShiYang River is taken as the research object.Using the data of land use/cover change information that analyzed by the technology of Envi and Arcgis of three remote sensing images in the study area.Adoption of land use/cover change single dynamic attitude,land use/cover degree comprehensive index and land use/cover center of gravity transfer and other methods to analysis the characteristics of land use/cover change in the upper reaches of ShiYang River in recent 30 years.Results show:(1)In 1986 and 2014,woodland and grassland were the dominant land use types in the study area.(2)During the period from 1986 to 2014,the changes of forest land,grassland and water area had experienced a process of first decreasing and then increasing,while cultivated land experienced a process of first increasing and then decreasing.(3)During the period of 1986-2014,the comprehensive index of land use/land cover in the study area changed little,and the land use/cover in 1986-2000 was in the development period,and the adjustment period was 2000-2014 years.
