Five factors,including slope,relief amplitude,distance to river, distance to cultivated land, and distance to road, were identified through principal component analysis( PCA). The inherent relations between five factors and Di( settlement density)were modeled by regression analysis. The results are as follows.( 1) The associations among Diand slope,relief amplitude,river,road are better modeled by the exponential decay line; with the buffer distance of slope, relief amplitude, distance to river and distance to road increasing, Didecreases.( 2) The associations between Diand cultivated land are better modeled by the quadratic polynomial line; with the buffer distance of cultivated land increasing,Diincreases first, and then dramatically decreases.( 3) The area within 500 m from the road,within 500 m from the cultivated land,within 1 600 m from the river,within the relief amplitude of 30-200 m,and the area within the slope of 0°-10° are the fitting land for settlements,and it is very important to lay the mountain settlements on those optimized regions.展开更多
