我国是个水资源既丰富又贫乏的国家 ,总量有 2 .8万亿 m3,但人均仅 2 2 60 m3,处于缺水的上、下限之间。北中国人均只有 1 1 2 7m3,接近缺水的下限 ,华北地区更少 ,仅 556m3。随着北中国社会经济的发展 ,缺水问题日益严重 ,不仅制约了社会经济的进一步发展 ,更造成了地下水资源破坏、黄河断流、土地荒漠化等一系列生态环境恶化问题。据估算 ,2 1世纪 50年代 ,北中国将缺水 2 0 0 0亿 m3,解决的根本途径是“南水北调”。今天考虑的“南水北调”,进到北方的水量仅 60 0亿 m3左右 ,只能是“解渴”工程 ,如要“重整河山 ,再造中国”,彻底解决北中国缺水和土地荒漠化问题 ,必须考虑和启动“大时空南水北调”,调除长江水外的西南诸水。这是一项“利在当代 ,功在千秋”的大业 ,更需要全民族不懈地努力和奋斗
China is a country rich in water resources and poor, with a total volume of 2. 8 trillion m3 but only a per capita population of 2 2 60 m3, which is between the upper and lower water deficits. In North China, the average per capita is only 1172m3, which is close to the lower limit of water shortage, with only 556m3 in northern China. With the development of social economy in northern China, the problem of water shortage is increasingly serious, not only restricting the further development of social economy but also causing a series of deterioration of the ecological environment such as the destruction of groundwater resources, the drying up of the Yellow River and land desertification. It is estimated that in the 1950s, North China would have 200 billion m3 of water deficit and the fundamental solution to this problem would be “South-to-North Water Diversion.” The “South-to-North Water Diversion Project” considered today will only bring about 60 billion m3 of water into the north. It will only be a “thirst-quenching” project. If it is to “reorganize rivers and mountains and rebuild China,” and to completely solve the problem of water shortage and desertification in North China, it must Consider and start “big time and space South-North Water Diversion”, tune the water except the Yangtze River water southwest. This is a great undertaking that is “beneficial to the present and will bring about a glimmer of success.” It also requires the unremitting efforts and struggle of the entire nation
