【摘要】 随着高密度城市日益增多,因城市形态改变而导致的热岛效应成为恶化城市居民生活环境和加剧能源消耗的重要因素。文章以ArcGIS软件为平台,基于最小二乘法,通过数理分析揭示上海市长宁区城市形态各因素对热岛强度的影响,并引入遗传算法,构建热岛模拟多因素数值模型通过黄浦区的数据检验模型的通用性和精确性。结果表明:基于长宁区数据构建的4个数值模型同样适用于黄浦区,具有一定的通用性,其中LHD模型的拟合效果最好。更多还原

【Abstract】 With the increasing number of high-density cities,the heat island effect caused by the change of urban form has become an important factor that makes the living environment of urban residents deteriorate and aggravates energy consumption.Based on the ArcGIS software,this paper reveals the influence of various urban factors on the heat island intensity in Changning district of Shanghai based on the least square method,and introduces the genetic algorithm to construct the multi-factor numerical model of the heat island simulation.The results show that the four numerical models based on the data of Changning district are also applicable to Huangpu district,which has certain versatility,and the LHD model has the best fitting effect.更多还原
