Grey Analysis of the Urban Heat Island Effect Factors of the Medium-sized City of Chuxiong on Yunnan Plateau
On the basis of the difference in temperature of the urban and the suburban areas from Nanhua Meteorological Station covering approximately 30 years, eight synthesized indexes were selected as the influencing factors of Chuxiong' s urban heat-island effects. The contribution level of the factors influencing the urban heat island effect of Chuxiong was analyzed by the grey relativity analysis method. The results show that density of population and electric power consumption are the main artificial factors for the formation of the urban heat island effect of Chuxiong, while the wind velocity and hours of sunshine are the main meteorological factors affecting the urban heat island effect of Chuxiong. The prediction results of the systematic coordinate gray prediction model indicate that there is an increasing trend of the urban heat island effect in Chuxiong in the coming five years.
