湖北省四湖地区湖泊水域近期变迁的遥感应用研究

A Study on the Recent Changes of Lake Area in the Four lake Area of Hubei Province by Using Remote Sensed Images

利用不同时期的ＬａｎｄｓａｔＭＳＳ和ＴＭ图像对本世纪５０年代以来研究区湖泊水域的面积变化进行了研究。结果表明，该区湖泊面积持续减少；５０年代初期至７０年代末期期间的减幅远大于８０年代以来的减幅。湖泊减少的原因，首推人类活动，自然因素也起到了重要作用。在调查研究的基础上，对合理利用与保护湖泊资源的对策进行了探讨。

In this paper, the recent changes of lake area in the Four lake Area were studied by interpreting on the multi temporal images of Landsat MSS and TM. The results show that the area of the lake has been decreasing since the early of 1950's of this century and the extent of decrease during the period of 1950's～1970's is far more than that of after the 1970's. The reasons for the changes were the human activities and the natural evolution. Based on the above mentioned, some suggestions were given on the rational utilization and protection of the lake resources in this area.
