摘 要：
在对新疆孔雀河流域1973年(MSS)、1990年(TM)、1999年(ETM)3个时期遥感数据进行解译的基础上,得到了研究区3个时期土地利用/覆盖类型变化的基础数据。根据这些数据,进行了土地利用/覆盖类型构成比重、单一土地利用动态度、综合土地利用动态度、以及土地利用程度变化分析。结果表明,1973~1999年间,研究区内土地利用/覆盖类型结构的重心,由草地、林地、盐碱地,转向草地、耕地、盐碱地,草地始终是研究区内面积比重最大的土地利用/覆盖类型;耕地、城乡工矿居民用地、草地面积大幅度增加,林地、水域、盐碱地面积大幅度减少;戈壁、沼泽面积减少幅度相对较小,沙地、裸岩石砾地的面积基本不变;区内各种土地利用/覆盖类型的变化及其相互转化程度非常剧烈;区内土地利用程度逐年提高,土地的开发利用处于发展期。

摘 要：
By interpreting three remote sense images of the Peacock River Basin(1973 MSS,1990 TM,1999 ETM),basic data about area of the land use/cover type of the basin in the last three periods are obtained.On the basis of these data,this paper carries out analysis on the proportion of land use/cover type,the dynamic degree of single land use,the dynamic degree of synthesis land use and the synthesis index of land use degree to study the land use/cover change in the Peacock River Basin between 1973 and 1999.Through these analyses,the results shows as follows: in 1973,grassland,woodland,and saline land were the main land use/cover type in the basin;in 1990 and 1999,grassland,agricultural land,and saline land became the main land use/cover type in the basin.The total tendency of land use/cover change in the study area from 1973 to 1999 is that: the area of agricultural land,residental land,and grassland was increased even more;the area of woodland,waters,saline land were decreased pretty more;the area of Gobi and swampland was decreased correspondingly less;the area of desert and exposed rock land was invariant on the whole.In the entire period of study,the change of land use/cover type and the transform between each land use/cover type in the study area were much severe;the degree of land use was enhanced year by year,in the period of expansion land development gradually enhanced.
