The Mountain Area Water Resources Condition Of Guangxi And Valid Exploitation Research

Guangxi is situated at the subtropics, the climate temperately, rainfall abundant, within the boundaries many is the mountainous region, also the terrain landform complex forms the drainage ditch vertically and horizontally, the brook is densely covered, is one of our country water resources richer regions. Southwest is similar to other provinces, the city, the area is same, frequently is "the rain on third then becomes the waterlogging, does not have the rain day after day to become the drought", "sails upstream the expensive like oil, the ground water whish whish class". In the mountainous area, the countryside, the suitable partial tiny brook year to year tired end of the month does not flow the rest. But in the Guangxi water resources year distributes not balanced, rains mainly concentrates in 4—9 month, accounts for the whole year above 70%--80%. Rainy season often falls the heavy rain, the rainstorm, creates slope soil erosion, and the frequency floods the waterlogged disaster. But in the dry season, specially spring, the autumn, often rains the insufficiency, frequently appears arid and serious is arid. The drought is restricts the Guangxi agricultural development most important natural disaster .The Guangxi 54% county city suffer from drought area 568,000 k m~2 for the agricultural arid every year average crops. Also the waterlogging dryly explained the Guangxi water resource...
