Abstract：The karst development of karst mountain areas in southwestern China is complicated,which brings difficulties to the development and utilization of underground rivers there.Based on the results of geo-logical surveys in these regions recent years,this work makes a systematic summary on the characteristics of karst landforms and karst development,and proposes 6 typical exploitation modes of underground rivers,i. e.(1)karst depression reservoirs in peak-cluster depression areas,(2)reservoirs formed by subterranean stream blocking in deep karst valley areas,(3)surface-underground combined reservoirs in karst valley are-as,(4)water diversion by digging tunnels in karst ridge fold zones,(5 )leading groundwater by motor-pumped wells in peak forest-plain areas,and (6 )Reservoirs by combined surface-subsurface underground streams in edges of fault-depression basins.These 6 models provide a practical reference for treatment in ac-cordance with local conditions,reasonable and efficient development and utilization of groundwater re-sources,and can effectively serve the national strategy of precise poverty alleviation.
