The main author	Data	Study area	Results
Cao et al.42	Landsat ETM+ data on July 3, 2001	Shanghai, China	There was a nonlinear relationship between LST and NDVI in Shanghai, but the positive value of LST and NDVI showed a significant linear relationship
Hager et al.43	AVHRR data from 1981 to 1999	Mongolia	In high latitudes, LST and NDVI were positively related
Ghobadi et al.9 (2013)	Landsat 5 data in 1998 and Landsat 7 data in 2002	the South Carle Sea watershed of Iran	There was a negative correlation between LST and NDVI
Zhou et al.10	Landsat TM data on August 27, 2010	Shenyang, China	LST and NDVI scatter plots showed “triangle” relation, the three directions represent water area, green land and cultivated land, construction land, respectively
Qu et al.11	MODIS data in 2011	Shiyang River Basin in Gansu, China	LST-NDVI scatter plots showed a trapezoid distribution
Liang et al.44	Landsat TM data in 2006	Guilin, China	NDVI and LST showed a negative correlation
This paper	Landsat 8 data on August 29, 2016	Yinjiang County of Guizhou, China	LST and NDVI scatter plots showed an “obtuse-angled triangle” distribution
