要:以新疆开孔河作为研究区,利用1990年、2000年与2010年Landsat-TM像数据和中巴资源卫星数据,摘
结合CIS技术,分新了研究区近20a土地利用/覆被变化,并对其变化原围进行分新,结果表明:1990一2010年,研究区其他林地、裸土地、耕地、滩涂温地、盘碱地和成镁用地面权呈现增加趋势,;其它建设用地、其它未利用地、灌术林地与中覆盖度草地面积呈现减少趋势,:利用转移短降可知,流城新增耕地面积主要来自草地和沙地,研究结果可为区城水土资源可持续利用及生态环境保护提供参考,

Abstract; The extraction of land cover information based on remote sensing has a direct significance for agricultural and for-estry production and environmental monitoring. In this paper, Kai-kong River Basin is selected as study area, by using 1990, 2000 and 2010 Landsat TM image data and CMB resoure satellite data, combined with GIS technology, the land use/cover change of the study area nearly 20 years is analyzed and the reasons for such changes are discussed. The results
show that : from 1990 to 2010, the land ar

地覆被是区域景观的外在表现和重要影响因素,不同土地覆被方式形成了不同的景观和景观结构[6-"].土地利用类型转换过程传递着人类社会活动与自然生态环境之间的物质循环与能量流动,研究其转换有助于及时掌握土地利用类型时空分布与变化过程[9-10]近年来随着人口不断增长,土地的大规模开垦,加剧了土地利用类型的改变,严重
