摘要 滇池流域生态区位重要,但研究资料表明区内还存在一定程度上的荒漠化。为较好发挥区内生态环境效应,本研究基于RS与GIS技术,对2000年、2008年和2015年滇池流域水蚀荒漠化进行分析,结果表明该流域内水蚀荒漠化主要分布在滇池流域东北部的盘龙区、官渡区、呈贡县和南部的晋宁县,且总体呈减少趋势。2000—2008年间水蚀荒漠化面积减少78.44 km2,年平均减少9.81 km2; 2008—2015年间减少速率较快,共减少218.89 km2,年平均减少27.36 km2。近年来滇池流域封山育林、人工造林和土地利用方式的改变,使水蚀荒漠化得到明显改善。

Abstract:Most of the Dianchi watershed is in the fragile ecological environment, which desertification problem is very prominent. This research extracted water erosion desertification from remote sensing images of Dianchi watershed in 2000, 2008 and 2015 by RS and GIS technology. The results show that the water erosion desertification mainly distributed in the northeast and south of the study area, and the overall trend is decreasing. The area of water erosion desertification decreased 78.44 km2 from 2000 to 2008, decreased 9.81 km2 every year; the area of water erosion desertification decreased 218.89 km2 from 2008 to 2015, decreased 27.36 km2 every year. People had closed hillsides to facilitate afforestation, reforested and modified of land use patterns improving water erosion desertification phenomenon of Dianchi watershed, in recent years.
