Impacts of Land Use Change on the Regional Climate: A Structural Equation Modeling Study in Southern China

Table 1

Rotated component matrix of principal component analysis.

	Principal component
	1	2	3
Cultivated land	0.746	0.025	0.422
Forestry	−0.048	−0.071	0.837
Grassland	−0.065	−0.026	0.817
Water bodies	0.788	0.265	−0.132
Built-up area	0.823	0.015	−0.257
Unused land	0.158	0.939	−0.050
Others	0.065	0.953	−0.046

Notes: (1) principal component analysis was used; (2) orthogonal rotation method with Kaiser standardized was used and converged after four time iterations.
