城市化对重庆市水源系统的影响

The Impact of Urbanization on Chongqing's Water Sources System

城市化进程的加快推动了经济的迅猛发展,但同时也对城市水源系统产生了极大的影响,为了保证重庆市的可持续发展能力,尽可能地减轻城市化带来的负面影响,保护、恢复和重建城市水源系统,特对重庆市多年降水量、地表水水质、地下水量等数据进行分析;结果证明:重庆市自城市化推进以来,地表水水质下降以及地下水量减少、降水量和地表径流量分别呈增大和减少的趋势。

The acceleration of the process of the urbanization boosts the rapid economic development and exerts large impact on urban water source system. In order to ensure the sustainable development capacity of Chongqing and to try to decrease the negative impact by urbanization,an important issue for Chongqing is to protect,remediate and reconstruct urban water resources system. The data analysis results of Chongqing＇s rainfall,land surface water quality,and underground water amount and so on indicate that since Chongqing＇s urbanization promotion,land surface water quality decreases,that underground water amount declines and that the rainfall and land surface runoff amount show the trend of increase and decrease respectively.
