兰州城市气候季节性变化与城市发展关系研究

hrough the ways of city-suburbs comparative analysis research the urban development of Lanzhou in forty years, which has caused the urban climate change. Especially we investigate the relationship between the urban climate change in different seasons and urban development. In the article, we can see the population of Lanzhou and the urban climate change in Lanzhou two independent variables, so we use the regression analysis to research the population increase cause the extent of the urban climate change. We can conclude that the thermal island of Lanzhou in winter was almost caused by man-made heat. In the other seasons, thermal island was also caused by man-made heat, but underlaying surface could change it, too. Man-made heat could cause the arid island, but it wasn’t the most important factor.
