- Abstract:
-
It is an important method to understand the growth patterns of the rural settlements by simulating their spatial growth. Illustrated by the example of the Tourist Economic Area around the Fanjingshan Mountain of Tongren, Guizhou Province, this paper used GIS spatial analysis function to calculate the comprehensive influence of the rural settlements and divide the settlements into different types of growth, and give the relative growth factor K value, and finally simulated the spatial growth using the improved MCR model. The results show that the model can better simulate the spatial growth direction and range of the rural settlements taking the ecological barriers and the different growth ability of the rural settlements into consideration. In the land development suitability of constraint, the higher the suitability degrees are, the more suitable the rural settlements is to grow. Under the growth rates of 0.5%, 1%, 2% and 3%, the region, respectively, 0.021, 0.042, 0.084 and 0.126 square kilometers of lands are provided for construction. And the rural settlement with larger growth area mainly concentrates in the surrounding towns and the river valley. Restricted by the ecological barrier, the rural settlements do not achieve growth when they meet the ecological barrier. The simulation results show that the direction of ecological policy regulation is conducive to the protection of the ecological environment, but the model is more effective in simulating spatial expansion. And simulation on time growth requires the combination of other models.
