| 摘 要： | 以GIS和RS作为技术支持,对滇池历时性遥感图像进行数据信息提取,分析自1974~2004年滇池周边土地利用的空间数据和属性数据,指出城镇占地面积增加,森林覆盖稀疏、不均匀;裸地面积上升等原因,导致滇池地表水污染、涵养和自净功能差,使滇池水质和水量依然面临严峻状况,从动态的角度揭示出滇池近30年来土地利用的变化对滇池环境污染的影响.

| Abstract: | The spatial data and property data of land exploration around the Dian Lake from 1974 to 2004 have been analyzed with the help of GIS and RS to show that the land for city has increased,that there is little and imbalanced forest covering,and that the increase of the bare land,which further has resulted in the pollution of the water on the land surface and worse self-purification of the water in the area of Dian Lake.The quality and quantity of the water in Dian Lake are facing severe challenge.The influence of land exploitation on the water circumstance of Dian Lake during the latest 30 years has been revealed from a dynamic point of view. |
