基于RS的佛山市土地利用变化的时空特征研究

Study on spatial-temporal feature of land-use change in Foshan City by Remote Sensing

对1988,1999年佛山市两期TM遥感影像数据加以处理,分析了土地利用程度变化值和土地利用动态度。土地利用变化的时空特征表现为近10年来城市用地面积沿主要道路迅速扩展,导致水域、耕地和林地面积大量减少,城市用地矛盾日益突出。

With the use of TM data of Foshan in1988and1999,land use types map of Foshan in1988and1999was compiled.The paper analyzes the land use change degree and land use dynamic degree in two years.The temporal-spatial feature of Foshan city land use change is that urban land rapidly extension has brought on largely decreasing of water area,cultivated land and forestland in the near ten years,the results is that contradiction of city land using is increasingly standing out.
