新中国成立以来,国家在防洪工程建设方面投入了大量资金,共建成水库8.3万余座,总库容4500亿立方米,新建和整修堤防20多万公里,主要江河开辟蓄(滞)洪区100多处,分蓄洪水能力达1000多亿立方米,初步建成了由堤防、水库、分(蓄)洪区、河道整治等组成的防洪体系。目前,七人江河一般能防御20～30年一遇洪水,取得了显著的效益。但由于种种原因,使防洪工程还不能适应经济发展的需要。主要表现为:一是现有工程老化失修、隐患重重、效益下降,新建工程资金短缺等,加之长期以来水利工程重建轻管,工程养护维修和更新改造没有固定的资金来
Since the founding of New China, the state has invested a large amount of money in the flood control project construction to build a total of more than 83,000 reservoirs with a total storage capacity of 450 billion cubic meters. More than 200,000 km of new embankments have been constructed and renovated. In many places, the flood diversion capacity reaches more than 100 billion cubic meters, and a flood control system consisting of dikes, reservoirs, sub-flood areas and river courses has been initially established. At present, seven rivers can generally prevent floods once in 20-30 years and have achieved remarkable benefits. However, due to various reasons, flood control projects can not meet the needs of economic development. Mainly as follows: First, the existing project aging disrepair, hidden dangers, the decline in efficiency, the shortage of funds for new construction projects, combined with water conservancy project reconstruction light pipe for a long time, engineering maintenance and repair and renovation do not have a fixed capital
