where HSI is the scarcity index of habitats ,nl is the equivalent quantum of biodiversity service for land use type l ,m is the corrected value of the protection ranking. For the nature reserves,
parks, scenic areas, and other land-use types, mare assigned values of to 1.75, 1.5, 1.25, and 1, respectively .The index vegetation type can be obtained from the digitized
maps of ecosystem type. The index of vegetation coverage (VC) can be obtained from the map of Normalized Difference Vegetation Index (NDVI).
The index of the habitat quality reflects the level of biodiversity.
The formula of habitat quality index (HQI) is as follows:
