根据历年的水文资料计算,一般年份我省可利用水量191亿立米,其中地上水102亿立米,地下水89.18亿立米。从目前的实际情况看,实际用水量超过了实际供水能力,如提取地下水,1986年为151.01亿立米,1987年为153.67亿立米。不论是浅井还是深井,都处于采大于补的状况。地表水1986、1987年仅能用到40—55亿立米,其主要原因是降雨少,另一个原因是上游省分修建水利工程多,汛后河道中没有那么多基流流入我省。现实的可供水能力,已达不到用历史水文年计算出的可供水指标。我省工农业生产的发展,迫切需要水资源的保证。目前水浇地面积为5370多万亩,年用水170亿立米左右,工业及生活用水30亿立米左右,合计200亿立米,比建国初期的用水量增加近4倍。今后随着工农业的发展,需水量还要增加。从气候情况看,
Calculated according to hydrological data over the years, the average annual amount of water available in our province is 19.1 billion cubic meters, of which 10.2 billion cubic meters of groundwater and 8.918 billion cubic meters of groundwater. From the current actual situation, the actual water consumption exceeds the actual water supply capacity, such as extraction of groundwater in 1986 to 15.01 billion cubic meters in 1987 to 15.367 billion cubic meters. Whether shallow or deep well, are in the mining situation is greater than the fill. Surface water 1986 and 1987 can only use 4.0-5.5 billion cubic meters, the main reason is less rainfall, another reason is that the upper reaches of the province to build more water conservancy projects, not so much after the flood in the river flows into the province. The actual capacity of water supply has reached the water supply targets calculated by historical hydrology years. The development of industrial and agricultural production in our province urgently needs the guarantee of water resources. At present, irrigated land covers an area of more than 5370 mu with about 17 billion cubic meters of annual water use and about 3 billion cubic meters of industrial and domestic water, totaling 20 billion cubic meters, nearly four times the amount of water consumed in the early days of the founding of the People’s Republic. With the development of industry and agriculture in the future, water demand will also increase. From the climate situation,
