| 摘 要： | 利用1995年、2000年的遥感图像数据和专题图,在空间图形库系统的支持下获得吉林省长岭县土地利用/覆被现状图,求得土地利用变化转移矩阵,对土地利用类型变化的幅度和土地利用类型之间转换的空间关系进行了研究。结果表明:1981—2000年,长岭县的土地利用变化总趋势是耕地、林地和盐碱地面积分别增加了4.76%、99.5%和9.86%,水域、居工用地变化不大,未利用地部分已被利用,草地面积减少了52.15%,并伴随着日益加剧的沙化和盐碱化。土地利用变化格局的主要驱动力是人口增长和农业用地结构调整。

| Abstract: | Using remote sensing data of 1995 and 2000 and thematic map, actual land use/cover map of Changling county of Jinlin province was obtained based on Spatial Cartographic Database System.The spatial relationship between change extent and change of land use type was studied.Results showed that from 1981 to 2000,there was a great change of land use in the county.The area of arable land,forest and saline-alkali land increased by 4.76%,99.5% and 9.86% respectively;water land and resident land changed a little;the area of the grassland decreased by 52.15%;wasteland was utilized.The main driving powers of land use change are population increase and structural adjustment of agricultural land. |
