基于ETM+遥感影像的城市热岛效应监测技术研究

Study on Hot Land in Guangzhou Based on ETM+

针对传统城市热岛效应监测技术方法的不足,探讨了利用热红外遥感影像进行城市热岛效应监测的方法。研究过程中采用密度分割法对广州市热岛分布状况进行模拟实验。最后结合其他统计资料,借助GIS等辅助工具,对热岛成因进行分析,提出缓解城市热岛效应的有效措施。实验结果表明,该种方法具有简便、准确、实用等特点,适合在我国城市开展进行热岛的常规监测。

Aiming at the shortage of traditional methods, this paper focuses on the method of monitoring city heat-land effects by heat- infrard RS. The experiment is applied in Guangzhou city by the method of density slice. GIS analyzes the cause of forming heat-land with statistics data, some methods of reducing city heat-island effect are showed. Results show that this method is convenient, accurate, practical, and fit to regular monitoring.
