中文摘要:
      新型城镇化要求优化国土空间格局,粗放、低效、拼资源型的传统城镇化发展模式已难以为继。按照综合效益最优和合理、高效、集约利用土地的目标,运用层次分析法在自然地理、经济发展、社会需求和生态保护层面构建了宏观的、分用途的低效用地适宜性评价指标体系,利用多因素综合评价模型计算4类用地的综合适宜值,根据土地用途最适合、优先级排序和邻域协调的配置规则,融合低效用地基础数据库与宏观确定的综合适宜值实现低效用地再开发方向优选。结果显示优化选择后土地利用组合类型依次为居住—商服—工业—公共服务设施—绿地。低效用地“宏微观基础数据库—宏观评价体系标准—宏微观数据融合”的再开发方向优选方法将为其他发达城市提供借鉴。
英文摘要:
      The new type of urbanization requires the optimization of the spatial pattern of land,and the traditional pattern of extensive,inefficient and resource intensive urbanization is no longer sustainable.According to the goal of optimal and reasonable comprehensive benefit,high efficiency and intensive use of land,a macro index system for evaluating the suitability of inefficient land use was constructed by using analytic hierarchy process (AHP) at the level of natural geography,economic development,social demand and ecological protection.The multi factor comprehensive evaluation model is used to calculate the comprehensive suitable value of four types of land use.The multi factor comprehensive evaluation model is used to calculate the comprehensive suitable value of the four types of land use,and according to the allocation rules of the most suitable land use,priority ranking and neighborhood coordination,the basic database of inefficient land use and the macroscopic comprehensive suitable value are integrated to optimize the direction of the redevelopment of inefficient land use.The results show that the combination type of optimized land use are arranged in the following order:commercial,industrial,public service facilities,green space.The optimization method of the redevelopment direction of underused land macro and micro basic database,macro evaluation system standard,macro and micro data fusion will provide reference for other developed cities.
