Relationship between Urban Development Scale and Heart Island Effect in Yunnan Plateau ChuXiong City

选取城市发展规模要素的指标,运用相关分析法,系统分析楚雄市1990～2009年期间城市规模的发展对其城市热岛强度的影响关系,发现建成区面积、非农业人口与城市热岛效应关系密切。再采用加权综合评价法计算城市发展规模综合指数,建立楚雄市城市发展规模与城市热岛强度的变化趋势图,发现近年来楚雄年热岛强度随着城市规模的发展逐年上升,建议通过树立新的城市发展观、搞好城市生态规划等几个方面来进一步改善楚雄"城市热岛效应"的负面影响。

The paper selecting the size of the elements of urban development indicators, using of correlation analysis, systematically analyses the development of its urban heat island intensity of relations in Chuxiong of Yunnan during the period 1990-2009 and finds that built-up area, non-agricultural population and the urban heat island are close. Then the paper using the weighted evaluation index scale of urban development, establishes the scale of urban development of urban heat island intensity and changes in trends in Chuxiong City, and finds that in recent years with the Chuxiong urban heat island intensity on the scale of the development year by year, then proposes new city by establishing concept of development, and improving urban ecological planning, and several other areas to further mend the negative impact of the Chuxiong urban heat island effect.
