摘要
Abstract
The long-term variation trend and periodicity of climatic elements of the lower reaches of Huaihe River-Linyi watershed were analyzed using Mann-Kendall statistical test and linear estimation. The study shows that the temperature in Linyi watershed has increase trend,and the increasing is more significant in winter. Rainfall in summer and autumn will decrease while increase in spring and winter and evaporation will decrease in the whole year. Rainfall in the central of linyi watershed,such as Mengyin.Feixian.etc. .will decrease more in summer,which will make the area drier in the future,thereby,water supply is insufficient in the climatic change situation.关键词
