Research on Optimization of Land Use Structure in BaoDing Urban Agglomeration Based on Ecological Security
Optimization of land use structure is an effective way to coordinate economic development with ecological environment protection and finally to achieve sustainable utilization of land resources.In this paper,we introduced ecological green equivalent and soil organic carbon storage as ecological indicators to evaluate the ecological benefit of land use structure in different development stages based on data of land use structure in Baoding from 2002 to 2009.We also used the TOPISIS model to evaluate the land use structure based on the same data set.We then built a multiple-objective model to get the optimal land use structure of Baoding in 2020 with consideration of both economic development and ecological protection.Finally we proposed suggestions of optimal land use structure to adjust the internal structure and protect ecological land.The results would provide reference and guidance for sustainable land use of Baoding city development and revision of overall land use planning
