水给城市带来了生机和活力,城市供水既是基础设施也是生活设施,是城市综合功能中不可替代的功能,有着极其重要的战略地位。本文对城市供水的发展战略提出一些构想,供研究参考。一、水乡的水源“危机”常州地处太湖以西,北临长江,南衔洮鬲两湖,京杭运河自西向东穿城而过,河道纵横,水网密布,可谓“江南水乡”。随着城市的发展,城市供水暴露出一些问题,存在着潜在的危机。(一)地下水过量开采引起地面下沉常州地下水以第二层承压水为主,允许最大开采量为16.2万吨/日,实际开采量从1957年的5.9万吨/日增加到目前24.7万吨/日,由于过量开采,造成区域性地下水位下降快,从 Water brings vigor and vitality to the city. Urban water supply is not only an infrastructure but also a living facility. It is an irreplaceable function in the city’s comprehensive functions and has an extremely important strategic position. This article puts forward some ideas for the development strategy of urban water supply for reference. First, the water source of the water “crisis ” Changzhou is located west of Taihu Lake, north of the Yangtze River, the South Qionglai two lakes, the Beijing-Hangzhou Grand Canal from west to east through the city and across the river, water network, can be described as “Jiangnan Water” . With the development of cities, some problems have been exposed in urban water supply, and there is a potential crisis. (I) Subsidence due to over-exploitation of groundwater The groundwater in Changzhou is dominated by the second-layer confined water, with a maximum allowable production of 162,000 tons / day. Actual production increased from 59,000 tons / day in 1957 to 247,000 at present Ton / day, due to over-exploitation, resulting in rapid decline of regional water table from
