【摘要】：城市土地是人类进行经济、社会和政治等各项活动的重要载体,其利用的合理与否与区域的兴衰密切相关。十三五规划报告指出,中国城镇化率已达到56.1%,预计到2020年,内地城镇化率将会升至60%。城市化取得巨大成就的同时,也暴露出建设用地利用粗放低效,土地开发次序混乱等突出问题,资源占有利用不合理,因而以节约应对浪费,以集约回应粗放,需要对现有城市土地的潜力进行释放。本研究基于生态位理论,在城市土地集约利用评价研究中,利用最适生态位解释城市土地集约利用标准,建立了生态位评价模型;综合考虑资源占有、现实需求以及未来规划,建立潜力测算模型;进行实证研究,对研究区进行了生态位评价、潜力测算、潜力释放时序配置。本文主要的研究工作及结论如下:(1)城市土地集约利用生态位模型构建。将生态位模型引入到城市土地集约利用评价研究中,通过比较各评价因子的Ai值与其最佳集约水平之间的差异,确定了各功能区不同制约因子;构建城市土地集约利用生态位评价指标体系,进行生态位评价,得到生态位分区,为潜力释放做好准备。(2)城市土地潜力测算模型构建。潜力是指在现有技术、经济和制度条件下,综合考虑资源占有、现实需求以及未来规划,通过提高土地集约利用程度,而提升城市建设用地利用效率和经济效益的空间。潜力分析包括规模潜力测算、经济潜力测算和城市土地潜力分区等三个方面的内容。(3)城市土地潜力释放时序配置。以生态位评价和潜力测算结果为基础,依据所有各类功能区的生态位、相对规模潜力高低、单位土地经济潜力大小、并结合社会经济发展规划、城市规划、计划安排等因素进行综合分析,确定各功能区的土地潜力释放时序配置。制定城市土地潜力释放时序配置方案,同时提出科学用地对策建议。
[Abstract]:Urban land is an important carrier for human to carry out economic, social and political activities. The rational use of urban land is closely related to the rise and fall of the region. China's urbanization rate has reached 56.1%, and it is expected that by 2020, the urbanization rate in the mainland will rise to 600.At the same time, great achievements in urbanization have also exposed extensive and inefficient use of construction land. The order of land development is chaotic and so on, the resource occupation and utilization are unreasonable, so it is necessary to release the potential of the existing urban land in order to save and cope with waste and intensive response to extensive. This study is based on niche theory. In the study of urban land intensive utilization evaluation, the optimal niche is used to explain the standard of urban land intensive use, and a niche evaluation model is established. Considering the resource possession, the realistic demand and the future planning, the potential calculation model is established. Carry on the empirical research, carried on the niche evaluation to the research area, calculate the potential. The main work and conclusions of this paper are as follows: 1) constructing the niche model of intensive utilization of urban land and introducing the niche model into the evaluation of intensive utilization of urban land. By comparing the difference between the Ai value of each evaluation factor and its best intensive level, the different restriction factors of each function area are determined. The evaluation index system of urban land intensive utilization niche is constructed, and niche zoning is obtained. Construction of urban land potential calculation model for potential release. Potential refers to the comprehensive consideration of resource possession, realistic needs and future planning under the conditions of existing technology, economy and system. By improving the degree of intensive land use, and improving the urban construction land use efficiency and economic efficiency space. Potential analysis includes the calculation of scale potential. Economic potential estimation and urban land potential zoning. (3) temporal distribution of urban land potential release, based on niche evaluation and potential measurement results. According to the niche of all kinds of functional areas, the relative potential of scale, the potential of unit land economy, and combined with social and economic development planning, urban planning, planning and other factors for comprehensive analysis. The temporal allocation of land potential release in each functional area is determined, and the urban land potential release timing allocation scheme is formulated, and the scientific land use countermeasures and suggestions are put forward at the same time.
