摘　　要：以土地生态承载力评价为基础,以环首都县域层面为研究主体,运用多目标规划模型,综合考虑经济社会和生态效益,对环首都区域土地利用结构进行优化。结果表明,2018年环首都区域13县(市、区)的土地生态承载力综合指数介于0.2~0.5,土地生态承载力水平较低,需要分区域进行土地利用结构优化;优化过程中,I区、Ⅱ区以生态效益优先为目标构建优化模型,Ⅲ区、IV区以经济和生态效益并重为目标构建优化模型,最终得到环首都4个区域的优化方案。该方案可实现环首都区域的经济与生态协调发展,对京津冀地区生态文明建设和可持续发展具有指导意义。Based on the evaluation of land ecological carrying capacity,the land use structure of the region around the capital was optimized by taking the county level around the capital as the research subject,using the multi-objective planning model,and comprehensively considering the economic,social and ecological benefits.The results showed that in 2018,the comprehensive index of land ecological carrying capacity of 13 counties(cities,districts)in the region around capital was 0.2-0.5,the level of land ecological carrying capacity was relatively low,which was necessary to optimize the land use structure according to different regions.In the optimization process,areas I andⅡbuilt optimization models of land use structure with the goal of giving priority to ecological benefits,and areasⅢand IV built optimization models land use structures with equal emphasis on economic and ecological benefits.In the end,the optimization schemes of the four areas around the capital were obtained.These schemes can realize the coordinated economic and ecological development of the region around the capital,and have guiding significance for the construction of ecological civilization and sustainable development in the Beijing-Tianjin-Hebei region.
