济南市小清河流域汛期降水时空演变规律分析
The spatial-temporal evolution law of flood season precipitation in Xiaoqing River Basin of Jinan
摘要
Abstract
Based on the long-term daily precipitation data from 7 rainfall stations in the upstream of Huan-gtaiqiao hydrological station in Xiaoqing River Basin of Jinan from 1977 to 2013 , the Mann-Kendall rank correlation test method, and the five-year moving average method were used for variation trends, the vari-ance spectral density diagram method was applied for period component, the sequence clustering analysis method was used for detecting and testing mutation component, and the R/S analysis method was used to analyze the variations of flood season precipitation at the basin. The results showed that:the temporal evolu-tion trends of flood season precipitation of different rainfall stations in Xiaoqing River Basin of Jinan were similar and had upward trends. Their spatial distributionshad obvious characteristics, which conforms to the overall pattern of Chinese precipitation distribution. Future trends of flood season precipitation at all of the 7 rainfall stations were upward. This research provided basic references for the resources sustainable develop-ment and construction of sponge city in Jinan.关键词
