表1 生态指标计算方法

Tab.1 Method for calculating ecological indicators

一级指标	二级指标	效应^①	计算公式
压力	DI	-	DI=R-N
压力	NDBSI	-	SI₁=$\frac{({S}_{1}+R)-(B+N)}{({S}_{1}+R)+(B+N)}$ IBI=$\frac{2{S}_{1}/({S}_{1}+N)-[N/(N+R)+G/(G+{S}_{1}\left)\right]}{2{S}_{1}/({S}_{1}+N)+[N/(N+R)+G/(G+{S}_{1}\left)\right]}$ NDBSI=(SI+IBI)/2
状态	VHI	+	NDSVI=(S₁-R)/(S₁+R) NRI=N/G NDVI=(N-R)/(N+R) VHI=PC1(NDVI,NDSVI,NRI)
状态	SMMI	+	SMMI=$\sqrt[　]{(N+{S}_{1})/2}$
响应	LST	-	L=gain×DN+bias T=K₂/ln(K₁/L+1) LST=T/[1+(λT/ρ)ln ε]-273.15
	WET	+	WET=0.151 1B+0.197 3G+0.328 3R+ 0.340 7N-0.711 7S₁-0.455 9S₂
	SI₂	-	SI₂=$\sqrt[　]{B\times R}$
