Evaluation of Construction Land Suitability and Reserve Resource Potential Based on GIS
In order to coordinate the relationship between ecological environment protection and economic and social development,and to promote the sustainable use of land resources.the land use in 2010 and 2020 is taken as data from the natural environment and social and economic factors to select the evaluation factor.Construction land suitability evaluation index system is built,the patch-generating land use simulation(PLUS)model is used to determine the index weight.Geographic information system(GIS)space analysis is conducted to evaluate the suitability of construction land and reserve resources potential.The results show that suitable area,more suitable area,generally suitable area and unsuitable area account for 5.84％,15.76％,24.09％,28.89％and 25.43％of the total land area in the study area,respectively,and the suitability grade is mainly unsuitable area.In terms of spatial distribution,the suitable areas are distributed in the central area of the old city,the central area of Yundong Economic Development Zone,the central area of Gantang Industrial Park and the government stations of various towns.The unsuitable areas and unsuitable areas are distributed in the mountainous areas with high elevation and large slope,which are the concentrated distribution of woodland and grassland.The area of reserve suitable construction land is 61 982.1 hectares,with suitable area accounting for 10.34％,34.6％and 55.04％of reserve suitable construction land respectively;the smallest suitable area is the main direction of the future urban development.The spatial distribution of the suitability level of construction land is consistent with the actual distribution of the land use status in the research area in 2020,which has reference significance for the regional planning of construction land.
