摘要

随着人口的增长和城市化进程的加快，城市生活垃圾的产生量日益增加。因此，诸如气味、火灾和强烈的沼气形成等问题都是由垃圾填埋场产生的。为了发现和解决这些问题，应定期监测堆填区。与实地研究相比，地理信息系统(GIS)和遥感具有空间分析能力，为垃圾填埋场的定期监测提供了快速和实用的解决方案。在这项研究中，通过开放源代码的Landsat8/9和Sentinel-2卫星图像监测伊斯坦布尔安纳托利亚一侧的Kömürcüoda垃圾填埋场。在此背景下，通过从Landsat热波段生成垃圾填埋场的地表温度(LST)图像，绘制了垃圾填埋场的地表温度异质性。此外，利用ArcMap软件的热点分析工具，确定具有统计学意义的高低地表温度点。本研究提出了一种简单的方法，使用开源卫星数据来监测地表温度并检测垃圾填埋场的地表温度异常。

Investigation of Land Surface Temperature Heterogeneity in Municipal Landfills by Satellite Images

With the increasing population and urbanization, the amount of municipal solid waste (MSW) is increasing day by day. As a result, problems such as odor, fire, and intense biogas formation originate from landfills. In order to detect and solve these problems, landfills should be monitored regularly. Geographic Information Systems (GIS) and Remote Sensing, with their spatial analysis capabilities, offer fast and practical solutions for the regular monitoring of landfills compared to field studies. In this study, Kömürcüoda landfill on the Anatolian side of Istanbul is monitored throughout 2022 with open source Landsat8/9 and Sentinel-2 satellite images. In this context, the surface temperature heterogeneity of the landfill was mapped by generating Land Surface Temperature (LST) images for the landfill from the Landsat thermal band. In addition, with the hotspot analysis tool of ArcMap software, points with statistically significant high - low LST values were determined. This study presents a simple methodology using open source satellite data to monitor LST and detect LST abnormalities on landfills.
