2. Ecological contribution rate of land use function transformation

The ecological contribution rate of land use function transformation refers to a certain type of land use change resulting from the change in the regional ecological quality. By calculating the ecological contribution rate of land use transformation, we can demonstrate the main type of the land ues transformation, which causes the increase or decrease [50], which can be expressed as follows:

$$\text{LEI} = (\text{LE}\_{t+1} - \text{LE}\_t)\text{LA/TA} \tag{3}$$

In Equation (3), LEI is the ecological contribution rate of land use function transformation. LEt+1 and LEt are the ecological quality index of the land use types at the beginning and end of the change, respectively, reflected by a certain land use change type. LA is the area of the change type; TA is the total area of the region.
