摘    要:利用1988年9月、2000年5月、2004年6月3个时期的陆地卫星遥感影像数据对宝鸡市金渭2区土地利用动态变化进行分析。选取了土地利用变化幅度、单一土地利用动态度、综合土地利用动态度和土地利用程度变化指数4个模型以及土地利用类型转移矩阵,利用RS和GIS信息处理技术,对宝鸡市金渭2区土地利用时空变化特征进行了分析。结果表明,总体趋势和基本特征是:耕地面积迅速减少,园地面积迅速增加,同时居民点及工矿用地也有较大幅度的增加,林地呈现减少趋势,而未利用地有增加趋势,水域面积变化不大。

关 键 词:土地利用变化  RS影像  宝鸡市金渭2区

Abstract:Dynamic change of land use in Jintai and Weibing districts of Baoji city were analyzed by using TM and ETM data that were acquired in September of 1988,May of 2000 and June 2004 based on the spatial analysis techniques supported by RS,GIS and other statistical methods.Five models were chosen to analyze the spatial-temporal change characteristics of land use,including the scope of LUCC,the single dynamic of LUCC,the comprehensive dynamic of LUCC,the index land use change degree and the conversion matrix of land use respectively.The overall tendency and basic characteristics of the change were as follows:The cultivated land decreased dramatically,the garden land increased dramatically,the residential area and industrial area grew with a relatively high speed,the forestry area showed a tendency of decrease,the unused land area showed a tendency of increase,and the waters area changed little.
Keywords:Land use change  Remote sensing image  Jintai and Weibing districts of Baoji city
