摘　　要：采用云南高原楚雄市和其郊区南华气象观测站近30年的温度差值作为衡量热岛效应的标准,并合理选取楚雄市8项综合指标作为城市热岛效应因子,运用灰色关联度分析法对影响楚雄城市热岛效应的因子群进行了贡献关联度分析。结果表明:人口密度和耗电量是造成城市热岛效应的主要人为因子,风速和日照时数是影响城市热岛效应的主要气象因子。灰色系统协调预测模型的拟合和预测表明楚雄城市热岛效应今后5年有增强的趋势。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.
