摘要:
随着我国城市化进程的快速发展，建设用地扩张引发的城市下垫面属性变化对城市热环境产生了日益严重的负面影响.以探究城市建成区平面形态与城市热环境的相关关系为研究目标，以西安市城六区为研究对象，基于Landsat遥感影像提取2002—2021年间的城市建成区边界并得出其平面形态的量化参数，同时通过地表温度反演计算出对应年份地表温度的各项指标，而后对两者进行相关性分析，结果表明地表温度最大值与建成区平面形态的面积、周长具有高显著性的相关关系，最终分别对两组数据通过曲线拟合建立数学模型并得出其具体的函数方程，为城市热环境的优化设计提供参考.
Abstract:
With the rapid development of urbanization in China, the changes of urban subsurface properties caused by the expansion of construction land have increasingly serious negative impacts on the urban thermal environment. This paper aims to investigate the correlation between built-up area morphology and urban thermal environment, and takes the six districts of Xi′an City as the research object, extracts the boundaries of the built-up area from 2002-2021 based on Landsat remote sensing images and derives the quantitative parameters of its morphology, and at the same time, calculates the indicators of the corresponding year′s surface temperature through the inversion of the surface temperature, and then conducts the correlation analysis between the two. The results show that the maximum value of surface temperature has a highly significant correlation with the area and perimeter of the built-up area, and the mathematical model is established by curve fitting for the two groups of data and the specific functional equations are derived, which can be used as a reference for the optimal design of the urban thermal environment.
