南京市本地地表水可用水量统计分析
Statistical analysis of available surface water quantity in Nanjing City
摘要
Abstract
Using a super long series data from 1956 to 2022,based on the data from 33 rainfall stations and 3 evaporation stations,the annual precipitation and evaporation in each administrative region in Nanjing were counted,calculated and analyzed.On the basis of statistical analysis of data from each single station,the arithmetic mean method is used to calculate the unit precipitation and evaporation,and then the area weighting method is used to calculate the water resource zoning of counties,cities,and administrative regions at all levels;Divide the underlying surface of the calculation unit into different types according to the runoff characteristics,and conduct runoff analysis on urban construction land,dry land,paddy fields,and water surfaces.Based on the runoff characteristics of different underlying surfaces,different runoff calculation methods and parameters are determined,the surface water resources under different horizontal years and inflow frequencies in each zone are clarified,and the available water quantity of local surface water in each administrative region of Nanjing is further determined.关键词
