| 摘 要： | 为了揭示植被改善城市热岛的量化关系,以重庆市主城区为例,在不同的尺度上分析了地表温度与归一化植被指数之间的相关性,分别从全局和局部出发分析了两者之间的线性关系.结果发现,在120m尺度上两者之间的相关性最强,空间相关场表明相关性在空间上呈现较强的异质性;全局普通线性回归和地理加权回归分析发现,两者之间没有显著的线性关系,这说明可能还存在其他多种因素的复杂影响.

| Abstract: | In order to reveal the quantification relationship of the vegetation improving the urban heat island, taking Chongqing main city proper as an example, this paper analyzes the correlation between land surface temperature (LST) and normalized difference vegetation index (NDVI) based on nine different spatial scales, and examines the linear relationship between LST and NDVI from global and local extents respectively. The results show that there is significant correlation between LST and NDVI especially on spat... |
