Table 1. Table 1The characteristic parameters used in this study were calculated using the formula

植被指数	波段	公式
归一化植被指数(NDVI)	B4(RED)、B8(NIR)	$N D V I = \frac{N I R - R E D}{N I R + R E D}$
陆地表面水分指数（LSWI）	B8A(NIR)、B11(SWIR)	$L S W I = \frac{N I R - S W I R}{N I R + S W I R}$
绿色叶绿素植被指数（GCVI）	B8(NIR)、B3(GREEN)	$G C V I = \frac{N I R}{G R E E N - 1}$
归一化建筑指数（NDBI）	B8(NIR)、B11(SWIR)	$N D B I = \frac{S W I R 1 - N I R}{S W I R 1 + N I R}$
水体指数（MNDWI）	B2(BLUE)、B11(SWIR)	$M N D W I = \frac{S W I R 1 - B L U E}{S W I R 1 + B L U E}$
水分指数（NDMI）	B8A(NIR)、B11(SWIR)	$N D M I = \frac{V N I R - S W I R 1}{V N I R + S W I R 1}$
