摘要: 利用乌鲁木齐市1990年8月6日、2001年7月11日和2013年7月4日三期热红外遥感数据,定量反演亮度温度,利用均值-标准差法对温度进行分级后评价城市热岛效应时间变化特征:1990、2001、2013年3个时段,乌鲁木齐市最大热岛强度分别为11.48℃,12.06℃和14.01℃;加权平均热岛强度分别为1.033℃,1.603℃,1.236℃;城市热岛比例指数分别为0.1054,0.3945和0.4328;乌鲁木齐市城市热岛效应在平均水平上呈现先增强、后减弱的趋势,最大热岛强度、热岛比例指数均增加,城市已初步形成区域内的"热岛",城市高温区温度将继续上升且面积存在扩展趋势.利用PSR模型构建指标体系对城市土地集约利用水平进行评价,在同时段内乌鲁木齐市城市土地集约利用水平和协调性均在提高.从评价结果出发,通过相关分析,得出基于土地集约利用的城市热岛效应影响因子包括:人口密度、建成区绿地覆盖率、地均国民生产总值、人均建设用地面积、人均道路铺装面积、地均固定资产投资,这些因子涵盖了经济、社会、环境三个方面.

Abstract: Landsat TM/ETM+ thermal infrared remote sensing data of Ürümqi on August 6, 1990, July 11, 2001 and July 4, 2013 are used to derive brightness temperature and classify the temperature using mean-standard deviation method.In 1990, 2001 and 2013, the maximum heat island effect intensity was 11.48 ℃, 12.06 ℃ and 14.01 ℃, respectively; the weighted average heat island effect intensity was 1.033 ℃, 1.603 ℃ and 1.236 ℃, respectively; the urban heat island ration index was 0.1054, 0.3945 and 0.4328, respectively. The results showed that in the study years, the average level of urban heat island effect in Ürümqi was first increasing and then decreasing; the maximum urban heat island intensity and development degree were both increasing, which illustrated that heat island had preliminarily formed in the city, the temperature of city's hot zones was continuously increasing and the hot areas had expanded. Using the PSR model to construct an index system to evaluate the level of urban intensive land use, it was obtained that during the same period, Ürümqi's intensive land use level and its coordination were in raising. From the evaluation results, one can see that the urban heat island effect factors based on urban intensive land use can be drawn by a lot of correlation analyses, which include population density, the green space coverage, the GNP per land area, the construction land area per capita, the road surface area per capita and the fixed assets investment per land area.

Key words: intensive land use, urban heat island effect, impact factors, Ürümqi City
