昆明主城松华坝饮用水源区水资源调查分析Investigation and Analysis of Water Resources in Drinking Water Source Area for Kunming City

Abstract: Kunming City is one of the cities for serious water shortage. With the rapid development of Kunming, contradictions of drinking water supply and demand are more prominent. As an important drinking water source in urban area, Songhuaba area is the origin of life of Kunming City, and its water resource quantity is directly related to the drinking water problem of residents in Kunming city. In order to solve the problem of drinking water in Kunming City, it is very important to allocate water resources scientifically and rationally, and to carry out the investigation and analysis of water resources in the water source area. According to the hydrological and meteorological data series in 13 stations, the hydrological analogy method and the typical year regulation method are used to calculate the water quantity, the available water and the reliability of water supply in the water source area, and the time-space distribution and the total water resources in the water source area are ascertained. It provides a reference for the effective solution of the optimal allocation and sustainable utilization of regional water resources.
