| Summary: | Guangxi is characterized by uneven distribution of water resources in time and space,serious flood and waterlogging,fragile ge ologic environment in karst regions,soil erosion and wide spreading of rock dese rts.I n supply and demands of water resources problems lie in insufficient storage cap acity,water pollution and poor management of water resources.It is concluded tha t all karst regions in Guangxi fall short of water in varying degrees except for those situated in northeast Guangxi.For developing water resources in karst reg ions in Guangxi the author puts forward the following measures:exploiting modera tely karst water to increase the ratio of ground water in water resources deve l opment;storing rationally both surface and ground water to enhance active capaci ty;overdrawing artificially the shallow karst water and recharging;exploiting ka rst rivers;buliding rain collection tanks;speeding up construction of large hyd r aulic and hydropower projects;building headwater forest areas;spreading water sa ving farming;strengthening protection and management of water resources environm ent and relocating extremely poor population inhabited in karst regions.The auth or also introduces briefly the optimum regional allocation of water resources. |
