摘  要:
【目的】监测渭库绿洲19892、001和2007年的土地覆被变化情况,进而分析土地覆被变化数量和结构及其驱动力。【方法】选择盐渍化比较严重的渭干河-库车河三角绿洲(简称渭库绿洲)地区为研究区域,从土地覆被/覆被变化的角度出发,结合当地的遥感和地理信息数据,利用遥感技术,对渭库绿洲1989、2001和2007年的土地覆被变化进行了监测。【结果】各土地覆被类型从数量和结构上都发生了较大变化。【结论】近十几年来随着研究区域经济的发展,人口的增加,用地需求量增加使得土地资源大规模开发进而使林地等自然覆被减少,农业用地增加。开垦后由于灌溉不科学,盐渍化加重,因而土地盐渍化成了该地区目前绿洲农业生产发展的最大问题之一[1]。

摘  要:
【Objective】This paper was mainly to monitor and analyze the land-cover change between 1989,2001 and 2007 in Weiku Oasis.【Method】From the point of view of land-Use/cover change,this paper chooses delta oasis of Wigan-Kuche River(Weiku Oasis),whose salinization is more serious in China as the study area and uses remote sensing technoique to monitor the land-cover change between 1989,2001 and 2007 in Weiku Oasis.【Conclusion】The results show that the various land cover types have undergone great changes in number and structure.In recent decades,along with the development of economy and growth of population,the demands of land resources have been increase,and then the natural cover such as forest has been decreased while agricultural land,has been increased.After reclaimation,there is lack of scientific method in irrigation,so that salinization became one of the most serious problems of local agricultural development.
