| 摘 要： | 以ASTER为数据源,提取研究区的地表温度,并从不同土地覆盖类型上分析地表温度与NDVI、植被覆盖度之间的定量关系.结果表明在各土地覆盖类型上地表温度与NDVI、植被覆盖度的线性关系并不明显,而在1%的间隔上平均地表温度与植被覆盖度呈明显线性关系,在0.01间隔上地表温度和NDVI关系呈分段线性关系,利用1%间隔的植被覆盖度更有利于分析地表温度和植被的关系.

| Abstract: | Land surface temperature(LST)was extracted from ASTER images,and the correlation among LST,NDVI and vegetation abundance in different land cover types was analyzed quantitatively.The result indicated that the linear correlation among LST,NDVI and vegetation abundance was not obvious in all land cover types,while the correlation between average LST and vegetation abundance in 1% interval scale was significantly strong.Otherwise,the relationship between LST and NDVI which was still complex showed the piecewise linear correlation even in 0.01 interval scale.It is a better way to use the vegetation abundance in 1% interval scale to investigate the interaction between LST and vegetation. |
