摘　　要：喀斯特山区、沙漠边缘及黄土高原是我国的生态环境脆弱带。喀斯特山区特殊的地质地貌环境,造成了喀斯特地区“地高水低”、“雨多地漏”、“石多土少”、“土薄易旱”,致使出现特有的湿热气候下的喀斯特干旱缺水。根据喀斯特地区的特点,提出了在喀斯特地区应因地制宜,采用“集雨工程”、“集流工程”、“提水工程”及兴建地下水库、溶洼水库、地表低坝等小微型水利工程,实施分散拦蓄、分散供水,以化整为零方式解决喀斯特山区整体性的干旱缺水问题。Karst Area, the margin of desert and loess altiplano are eco-environmental frail zones in China. Due to the especial geological environment of karst, the river is deep and land is high, the land is leaky though the rainfall is plentiful, the soil cover is lesser than rock exposed, the soil cover is too thin to maintain moisture. It results in drought in wet hot climate. On the basis of the analysis on karst characteristics, the models of water resource utilization were put forward. The rain collection, runoff gathering, water upgrade, building underground and depression reservoirs, lower dams in surface are better models for karst water utilization. The lack of water in karst area may be settled with dispersing storage, scattering supply and breaking up the whole into parts.
