Optimization of Rural Settlement Layout based on MCR and InVEST models
Taking Suzhou District as the research area,on the basis of analyzing the layout characteristics of the current rural settlements,this paper uses the minimum cumulative resistance model(MCR)and InVEST to evaluate the location suitability and importance of ecological services,takes ecological security as the first principle,establishes the division standard,comprehensively evaluates the results,and proposes a zoning optimization control strategy.The results show that:(1)affected by the geomorphology of the Hexi Corridor,the rural settlements in Suzhou District basically conform to the distribution characteristics of low elevation and low slope,but 42%of the rural settlements are still inaccessible,and there are problems such as the overall distribution and the per capita settlement area is too large.(2)The zoning area of Suzhou location suitability was distributed in a spindle shape,and the distribution of the current rural settlements was basically reasonable;the importance of ecological services has changed from high to low,and the zoning area has gradually decreased,and the distribution of rural settlements and the importance of ecological services have caused great conflicts.(3)Four optimization models of local urbanization,agglomeration enhancement,restricted development,and ecological relocation were proposed by comprehensively considering factors such as ecological protection,economic development,and social policies in Suzhou District.
