基于GIS的山区土地利用变化研究——以石家庄西部山区为例

Analysis of the Change of the Land-use Based on GIS

利用1987和2000年TM影像数据,借助GIS软件对石家庄西部山区的土地利用/覆被变化进行了研究。结果表明:该区耕地被大量占用,草地面积大范围减少,水域面积萎缩,土地利用程度总体上处于调整期,人类对土地利用的影响十分明显。最后,提出了山区土地可持续利用的措施。

The western mountain area of Shijiazhuang belongs to the middle part of Taihang Mountain area in Hebei Province. Its ecosystem fragility and sensitiveness are all remarkable. In the article, the change of the Land -use in the area was studied and the land -use data was from TM image in 1987 and ETM in 2000 by geographical information system software Arc/Info and Arcview.
