Then, the ESV of each land use type and each service function and the total ESV were determined as:

ESVk ¼ X f

Ak � VCikf (8)

ESVf ¼ X k

Ak � VCikf (9)

ESV ¼ X k

X f

Ak � VCikf (10)

where ESVk, ESVf, and ESV stand for the ESVof land use type k, service function f, and all the ecosystems (Yuan ha−1 year−1), respectively; Ak stands for the area of land use type k (ha) and VCikf stands for the value coefficient for land use type k with ES function type f (Yuan ha−1) in year i.
