| 摘 要： | 位于云南省会昆明盆地内的滇池流域是滇中岩溶和石漠化较为发育的地区,石漠化总面积225.56 km2,占流域总面积的7.71%,占岩溶总面积32.69%。石漠化主要分布在望海山、大板桥—呈贡、黑林铺、海口、梁王山、上蒜片区,其中又以北东部的大板桥片区石漠化最为严重。石漠化已造成流域内水土流失加剧、可耕地面积减少、土壤涵养水源能力降低及生态环境恶化等危害。通过地面调查和ETM遥感解译,查清了流域内石漠化的发育分布与碳酸盐岩的岩性及其组合、岩溶作用、地形地貌、气象等自然因素、人为因素和工业污染关系密切。针对石漠化的形成原因,提出了生态修复、农田基本建设、水资源开发利用、农村能源建设、小集镇建设、土地合理利用等治理措施。

| Abstract: | Dianchi watershed is located in Kunming basin, Yunnan Province. Karst rocky desert is comparatively developed, with 225.56km2 of rocky desert that accounting for about 7.71% of the total area and 32.69% of the karst area in Dianchi watershed. The deserts mainly locate in Wanghaishan, Dabanqiao-Chenggong, Heilinpu, Haikou, Liangwangshan and Shangsuan etc. Among them, the most serious desertification area is the district in the northeast of Dabanqiao. The desertification has led to detriment as serious soil loss, arable land decrease and soil moisture retention capacity reducing as well as environmental degradation. Through field survey and ETM interpretation, it is found that the desertification is intimately related with natural factors as lithology, karstification, geomorphology and climate, and with human factor, as well as with industrial pollution. To against the genesis of the desertification, the governing measures are put forth, such as ecological restoration, farmland capital construction, water resource exploitation, rural power source construction and small town build as well as reasonable use of land. |
