    摘要:

    基于1987、2000年两期TM、ETM+遥感数据资料,利用ArcGIS提取石家庄西部太行山区的景观类型转移矩阵,并结合重心模型,从时间和空间上对景观格局动态变化进行分析。结果表明:(1)1987~2000年,景观基质均为耕地,林地、草地、水域、建设用地和未利用土地作为斑块单元镶嵌其中;耕地、草地和水域的面积均为减少,其中草地面积减少量最大,主要向林地转化;林地、建设用地和未利用土地的面积均为增加,其中建设用地面积增加量最大,主要由未利用土地转化而来。(2)1987~2000年间,水域重心迁移距离最大;耕地、水域和建设用地的重心偏移方向为北偏西;林地和草地的重心偏移方向为北偏东;未利用土地的重心偏移方向为南偏西。

    Abstract:

    Based on the remote sensing data of Landsat TM and ETM+(1987,2000), the transfer matrix of landscape types were extracted using ArcGIS software, and the spatial and temporal change of landscape pattern was analyzed using barycenter transfer model in the western Shijiazhuang, Taihang Mountains. The statistics on areas and percentages of landscape types shows that cultivated land had been dominating landscape pattern inlaid by some small pieces of forest land, grass land, water area, building land and unused land from 1987 to 2000.The analysis on transfer matrix of landscape pattern shows that the areas of cultivated land, grass land and water area decreased, among which the area of grass land decreased most rapidly resulted in the converting of grass land into forest land; and the areas of forest land, building land and unused land increased, among which the building land increased most greatly with most coming from unused land. The study on barycenter transfer model indicates that from 1987 to 2000, the barycenter transfer direction of cultivated land, water area and building land was west-north, with the furthest barycenter transfer distance of water area, and the barycenter transfer direction of forest land and grass land was east-north, only the barycenter transfer direction of unused land was west-south.
