城市热岛效应的出现对能源消耗、物质循环以及城市居民的健康均产生了不利影响.因此,准确计算热岛指标并对城市热岛效应进行定量监测,对于改善城市生态环境具有重要意义.本文针对城市热岛指标计算复杂效率低、精度不高的问题,提出基于全球经纬度剖分网格模型(GeoSOT)的热岛足迹、热岛容量的计算方法.以北京市东、西城区作为研究区域,对疫情前的2014—2019年夏季进行了热岛指标的计算,并结合高斯模型法的计算结果进行对比分析.结果表明:基于GeoSOT网格的热岛指标计算减少了数据冗余,在误差范围内快速、准确地计算热岛指标,精准反映热岛效应发生的空间范围以及显著程度.
Calculation of urban heat island indicators based on GeoSOT grid
The emergence of the urban heat island effect has adverse effects on energy consumption,materials circulation, and the health of urban residents.Therefore,accurate calculation of heat island indicators and quantitative monitoring of urban heat island effect are of great significance for improving the urban ecological environment. To solve the problems of complexity,low efficiency,and accuracy in calculating urban heat island indicators,this paper proposed a calculation method for heat island footprint and heat island volume based on geograhic coordinate subdividing(GeoSOT) grid. Taking Dongcheng and Xicheng districts in Beijing as the research area,the heat island indicators were calculated for the summer of 2014-2019 before the epidemic,and the calculation results were compared and analyzed combined with the Gaussian model method. The results show that the calculation of heat island indicators based on the GeoSOT grid reduces data redundancy, and it calculates heat island indicators within the error range quickly and accurately. The calculation reflects the spatial range and significance of the occurrence of the heat island effect.
