摘要:
城市热岛效应作为城市化进程的负效应,其成因具有复杂性和地域性特征.以西安市为例,基于多元目标分析的主成分方法定量计算了不同影响因子对西安市热岛效应的贡献度大小,并以此为基础,最终筛选了城市人口、人均拥有道路面积、人均拥有机动车数、人均绿化面积、建成区面积、降水量及平均风速7个主要因素作为西安市热岛效应的主要成因;最后,从调整城市规划思路、控制工业热源、调控民用热源等三个方面为出发点构建了应对西安市热岛效应的宏观调控体系,其内容由3个一级指标、12个二级指标和5个三级指标构成.对应对和缓解西安市热岛效应具有积极的指导意义,也为其它城市应对热岛效应提供范式参考
Abstract:
The Urban Heat Island(UHI)have the negative effect on the urbanization, characteristic of the complexity and the regional otherness. In this paper, the way of Principal Component Analysis(PCA)with the multi-purpose way were selected to calculate the UHI contributive. The results showed that, the main reason for UHI was the total population as well as the per capita area of road, per capita number of motor vehicle, per capita green area, construction area and even the rainfall and average velocity of the wind. A macro-control system for reducing the UHI effect were set up for a adjusting urban planning, controlling industrial heat and regulating the civil heat for Xi′an. It includes 3primary index,12secondary index and 5third index, which have a positive significance to respond and relieve the Xi′an Urban Heat Island effect, and also provide a reference for other cities to respond and relieve the UHI effect
