宝鸡市是陕西省第二大工业城市,地表水资源据渭河(魏家堡站)、清姜河、千河等水文站资料统计,全市多年平均径流量41.27亿m~3(其中渭河38.8亿m~3)。城市用水主要靠开采地下水,1974年日用水量9.66万m~3,到1984年增加到18.13万m~3。随着城市建设的发展,工业用水日益增多,但重复利用率很低。万元产值用水量415m~3,高出北京工业用水的2倍,城市生活用水量每年0.816亿m~3。由于过量开采地下水,已经破坏了原来的天然平衡, Baoji City is the second largest industrial city in Shaanxi Province. According to statistics of Weihe River Station (Wei Jiabao Station), Qingjiang River and Qianhe Hydrological Station, the surface water resources in the city have an average annual runoff of 4.127 billion m 3 (including 3.88 billion Weihe River m ~ 3). The urban water use mainly depends on the exploitation of groundwater. The daily water consumption was 96,600 m 3 in 1974 and increased to 181,300 m 3 in 1984. With the development of urban construction, industrial water use is increasing, but the recycling rate is very low. The output value of 10,000 yuan is 415m ~ 3, twice that of industrial water in Beijing, and the annual urban domestic water consumption is 0.816 billion m ~ 3. Due to the excessive exploitation of groundwater, the original natural balance has been destroyed,
