An Analysis Study of the Impact of Urbanization on Rainfall in Wuhan

On the base of the hourly rainfall data of 102 weather stations of Wuhan in 2012, this paper calculates the area rainfall by using the Tyson polygon spatial interpolation method and applies the multiple linear regression model to analyze the impact of urban construction activities on the rainfall. It is concluded that from the perspective of the annual rainfall, rainfall and average temperature show a significant negative correlation, and this effect is also very significant in summer. This effect is also very significant in summer. At the same time, urban construction activities have a certain impact on rainfall in spring, summer, and autumn, which is reflected in the area of green area, water area and road density in the region. Among them, rainfall is most affected in summer.
