摘要
植被是城市生态系统的重要组成部分,在提升热舒适度方面起至关重要的作用。以国家森林城市龙泉市为研究对象,利用2003年、2010年、2017年三期遥感数据提取植被覆盖度、反演地表温度,运用差异分区和叠图分析方法研究植被覆盖度及地表温度时空演变,运用空间统计与线性回归方法研究植被覆盖度与地表温度耦合关系。结果表明:龙泉市植被覆盖度与地表温度均呈上升趋势;植被覆盖度与地表温度呈现明显空间集聚性;植被覆盖度处于不同水平时,与地表温度的线性相关性存在差异。
Vegetation is an important part of the urban ecosystem and plays a vital role in improving thermal comfort.Taking the national forest city Longquan City as the research object,using the remote sensing data of 2003,2010 and 2017 to extract vegetation coverage and invert the land surface temperature.The spatial and temporal evolution of vegetation coverage and land surface temperature is studied by using differential zoning and overlay analysis methods.Spatial statistic and linear regression method are used to study the coupling relationship between vegetation coverage and surface temperature.The results demonstrate that the vegetation coverage and land surface temperature of Longquan City shows an upward trend;the vegetation coverage and land surface temperature shows obvious spatial agglomeration;when the vegetation coverage is at different levels,the linear correlation with land surface temperature is different.
