中文摘要:
      基于遗传算法优化的投影寻踪模型(GA-PPE),利用投影寻踪模型解决承载力评价指标权重拟定的主 观性过强问题,从经济、社会、生态三系统构建城市建设用地综合承载力评价指标体系,采用 2009—2017 年的 相关指标统计数据,对辽宁省 14 个城市的近九年的城市建设用地综合承载力的差异进行评价与分析,得出以 下结论:(1)沈阳、大连作为辽宁省两座副省级城市,其城市建设用地综合承载力在九年内均位于全省前二位; (2)在辽宁沿海经济带及沈阳经济区的区域发展带动下,营口、盘锦、辽阳和鞍山等城市的建设用地综合承载 力在省内位居前列,并且不断提高;(3)辽西北城市的建设用地综合承载力普遍较低,位于全省末位;(4)沿海 经济带中的丹东、葫芦岛及沈阳经济区中的抚顺、本溪等城市的建设用地综合承载力与区域内其他城市有较大 差距,区域承载力水平参差不齐。
英文摘要:
      Based on the genetic algorithm optimized projection pursuit model (GA-PPE) and combined with the projection pursuit model used to solve the problem of excessive subjectivity in the formulation of the weight of the carrying capacity evaluation index,this paper constructed the comprehensive carrying capacity evaluation index system of urban construction land from the three systems of economy society and ecology by adopting relevant indicator statistics from 2009 to 2017 to evaluate and analyze the differences of the comprehensive carrying capacity of urban construction land in 14 cities of Liaoning Province in the past nine years. The results were shown as follows:(1) Shenyang and Dalian,which were the two vice provincial cities in Liaoning Province,had the top two comprehensive carrying capacity of urban construction land in the whole province from 2009 to 2017;(2) driven by the development of Liaoning Coastal Economic Belt and Shenyang Economic Zone,the comprehensive carrying capacity of construction land in Yingkou,Panjin,Liaoyang and Anshan was in the forefront among other cities within Liaoning Province and was constantly improved;(3) the comprehensive carrying capacity of construction land in the northwest cities of Liaoning Province was generally at the bottom line;(4) the comprehensive carrying capacity of construction land in Dandong and Huludao in the coastal economic belt,and Fushun and Benxi in Shenyang Economic Zone had a big gap with other cities in the region,and the level of regional carrying capacity was uneven.
