摘要
在经济快速发展的现代社会,城市热岛效应带来的影响越来越突出,严重威胁着人们的身体健康。因此,本文选择了与热岛效应强度有关的一个因素,即城市扩张,来研究两者之间的关系。本文选以太原市2004—2020年遥感影像数据为基础,使用ArcGIS 10.2和ENVI 5.3作为处理数据的平台,得到了太原市的土地利用现状图以及城市地表温度分级图,以此来分析太原市近20年来城市扩张的情况,并判断其对地表温度的影响情况。研究结果表明:①近20年来太原市的建设用地的面积增加了1124.3072 km^(2)城市扩张情况较为明显;②太原市20年间的高温区面积及城市热岛效应均有所增加;③太原市的热岛效应所产生的高温区随建设用地的扩张呈现增长趋势。
In the modern society with rapid economic development,the impact of urban heat island effect is more and more prominent,which seriously threatens people's health.Therefore,this paper chooses a factor related to the intensity of heat island effect,namely urban expansion,to study the relationship between them.Based on the remote sensing image data of Taiyuan city from 2004 to 2020,using ArcGIS 10.2 and ENVI 5.3 as the data processing platform,this paper obtains the land use status map and urban surface temperature classification map of Taiyuan City,so as to analyze the urban expansion of Taiyuan City in recent 20 years and judge its impact on surface temperature.The specific results of the study are as follows:1.2004 to 2020 Taiyuan City's construction land area increased by 1124.3072 km^(2),it can be seen that Taiyuan City's urban expansion is more obvious;2.From 2004 to 2020,the area of the high temperature zone in Taiyuan City increased,which showed that the intensity of the urban heat island effect in Taiyuan City increased;3.In the past two decades,the high temperature area produced by the hot island effect of Taiyuan City has also shown an increasing trend with the expansion of construction land,and is distributed in the area where the construction land is located,which shows that the urban expansion of Taiyuan City has a certain influence on the heat island effect.
