This report is a series of study that we pay attention to gain the planning standard of land use covered with green district for human environment-friendly in an urban area. So, we investigated the secular change of temperature-humidity to compare not only the regression coefficient with the difference between the two peaks of temperature, relative humidity and vapour pressure in the period of populated urbanization, but also the moving average for 5 years with 10 years. And, we examined the characteristics of temperature-humidity change and the relationship between this change and the change of population density in 8 weather types of cities that 135 weather points were classified according to the principal component scores of 4 axes which were represented 19 meteorological indices.
