定西市城市供水主要依赖于西部的内官—香泉盆地地下水。本文从定西市城市供水水源地水文地质特征和地下水动态分析入手,指出由于长期的超量开采导致地下水位急剧下降,地下水资源面临枯竭的局面。如何有效的利用地下水资源,以满足定西市城市经济的可持续发展已成为十分紧迫问题。除了采取节水措施,提高水资源的利用率外,跨流域调水是中远期解决定西城市供水的唯一解决途径。
Dingxi city water supply mainly depends on the western region of the inland - Xiangquan basin groundwater. This paper starts with the hydrogeological characteristics and groundwater dynamic analysis of urban water supply sources in Dingxi City, and points out that due to the drastic decline of groundwater table due to long-term over-exploitation, groundwater resources are facing depletion. How to effectively use groundwater resources to meet the sustainable development of urban economy in Dingxi City has become a very urgent issue. In addition to taking water-saving measures to improve the utilization rate of water resources, inter-basin water transfer is the only way to solve the water supply in Dingxi City in the long-term.
