摘要
土地利用变化是全球变化中的重要组成部分,是短期内人类活动对自然环境施加影响的显著表现形式.本文基于遥感和地理信息系统技术,利用LandsatTM图像的解译成果,分析了库尔勒市1996～2004年土地利用变化的空间分布特征.研究表明：在这8年的时间里,库尔勒市裸岩石砾地、沙地和园地的转移趋势明显,三者的转移率分别达到32.28%、20.16%和14.98%,主要以裸岩石砾地内部向工矿用地、居民点用地、水利设施用地、交通用地和沙地转移,牧草地和荒草地内部向耕地和沙地转移,耕地内部向园地和盐碱地转移等类型为主.同时,各类土地利用的净变化呈现出明显的区域差异.
The land utilization change is important constituent in the global change , and it is a remarkable manifestation of the influence that human activity exerts to the natural environment in the short-term. Based on remote sensing and geographic information system technology,and using the translated results of the landsatTM image , the land utilization change and spatial distribution eharaeteristies of Korla city from1996 to 2004 were analyzed. The research indicated that in these 8 years, the shift tendency of bare rock gravel land, sand and the field is obvious, Their shift rates respectively achieved 32.28%, 20.16% and 14.98%. The bare roek gravel land mainly shifted to the industrial and mineral land, residential area uses, water conservation, and transportation use. Pastures land and weed changed to farming use and sand land, the farming land shifted to the field and the saline and alkali land primarily. At the same time, each kind of land utilization change presented the obvious region difference.
