摘　　要：攀西地区降水季节分配极度不均,低山区域旱坡地多,成土母质多为第四纪红色粘土,土壤风化深,土层深厚,质地黏重,是建造微水工程的有利条件。调查结果表明,长条隧洞式地下蓄水池在攀西地区分布最多。这种蓄水池顺着山坡建造,埋于地表1 m以下,不影响地表农作,保证了农作物的播种面积和产量。攀西地区地下蓄水池类型多样,均具有明显的经济效益、生态效益和社会效益,实际生产中可根据当地的地质地形条件和经济发展水平选择适宜的地下蓄水池形式。As the rainfall in Panxi region varies greatly in different seasons, great deals of droughty sloping fields distribute in the low mountain area, and the 4th epoch＇s red clay is the primary parent material. With deep weathering degree, the soil layer is deep, and the soil is sticky, which provide facilities for the building of mini-type reservoir project in Panxi region. The investigation results show that the strip-tunnel underground conservation pool is the main mini-type reservoir in Panxi. Built along the hillside and buffed more than lm deep underground, the pool didn＇t influence the farming on the earth and guaranteed the planting area and yield. There are many kinds of underground conservation pools in Panxi region, which achieve significant economic benefits, ecological benefits, and social benefits. In practice, we should choose the most feasible type of underground reservoir pool based on local geologic and landform condition and economic development.
