开封市城区公园对城市热岛效应的缓解效果研究

Research on Mitigation Effect of Urban Park on Heat Island Effect in Kaifeng City

城市热岛效应是影响城市生态系统的重要因素,也是影响城市生态文明建设的重要因素。公园作为城市内生态系统的重要组成部分,具有较高的生态服务功能,其布局和质量反映了一个城市的生活质量,同时也对促进城市可持续发展、保障城市安全起着无可替代的作用。利用遥感影像反演技术获取地表温度,通过对比不同时期、不同地表地物构成所导致的地表温度分布情况,探讨了城区公园对开封市城区热岛效应的缓解效果。

Urban heat island effect is one of the important factors affecting urban ecosystem and urban ecological civilization construction.As an important part of the urban ecosystem,the park has a high ecological service function.Its layout and quality reflect the quality of life in a city,and play an irreplaceable role in promoting the sustainable development of the city and guaranteeing the security of the city.The land surface temperature was obtained by using remote sensing image inversion technology,and the mitigation effect of park on urban heat island effect in Kaifeng City is discussed by comparing the distribution of land surface temperature caused by different periods and different surface features.
