【摘要】：当前,我国的城镇化发展已经进入了快速阶段,城镇化成为了国家发展过程中推行的重要战略之一。土地承载了人类活动的所有内容,城镇化的发展,归根结底是土地利用方式的转变。城镇化进程中,城乡土地利用结构与布局的不合理,成为了制约城镇化战略实施效果的严重阻碍。鄱阳湖生态经济区作为我国主体功能区划分汇总的重点开发区之一,处于城镇化高速发展的阶段,如何在快速发展的城乡土地利用方式转变过程中摆正方向,合理优化城乡土地利用规模结构与空间布局,是鄱阳湖生态经济区从快速城镇化转向新型城镇化过程中所需探讨的重要命题。本文首先对建国以来鄱阳湖生态经济区城镇化发展历程进行了梳理,提出城乡土地利用与城镇化发展的关系。将研究区划分为八个方位,对城乡土地利用时空格局进行了分析。分析得出,城乡建设用的利用现状和增长水平,指向西南方向,即南昌、新余方向。说明,无论是城市规模,还是发展增速,排名仍然是以大南昌都市圈为靠前。而在对各城镇、乡村进行经济发展和特色产业的分析后得出,城乡体系格局的优化,结合城乡建设用地的格局,应发展当地特色产业,合理布局城乡土地利用空间,最大化土地利用效率,使得城乡土地利用格局在新型城镇化进程中具备可持续发展的动力。其次,从人口、社会、经济出发,探讨城乡建设用地扩张的驱动力,探寻驱动城镇、乡村扩张的关键因素。运用灰色关联度方法构建城乡建设用地扩张驱动力模型,对鄱阳湖生态经济区32个评价单元2005-2010年城乡建设用地扩张进行分析,对研究区影响城乡建设用地扩张的8个经济社会发展因素进行分析和排序,得出研究区城乡建设用地扩张的主要驱动力。研究得出,城镇工矿用地扩张驱动力来源于社会工业化水平和经济发展水平。农村居民点扩张驱动力来源于农民人均占有耕地、农村人口收入水平和农业生产水平。最后,运用生态位适宜度模型,构建涵盖商业发展、工业发展、农业发展和环境保护四大类指标,共17项具体指标的生态位适宜度评价体系,将鄱阳湖生态经济区划分为商业发展主导区、工业发展主导区、农业发展主导区、环境保护主导区和禁止开发区等五个类型区域。并结合主体功能区建设目标以及其分区成果,优化鄱阳湖生态经济区城乡土地利用空间布局。获得鄱阳湖生态经济区综合分区结果,划分为核心增长极、区域中心、一级扩散圈、二级扩散圈和二级扩散带和禁止扩散圈。根据土地利用综合分区结果,在生态位适宜度模型的基础上,提出城乡土地利用结构优化平衡模型,对研究区城乡建设用地的结构进行了优化。根据城乡建设用地结构与布局优化结果对研究区城乡区域差异化土地利用政策提出了建议。
[Abstract]:At present, the development of urbanization in China has entered a rapid stage, urbanization has become one of the important strategies in the process of national development. Land carries all the contents of human activities, and the development of urbanization is, in the final analysis, the transformation of land use mode. In the process of urbanization, the unreasonable structure and layout of urban and rural land use has become a serious hindrance to the implementation of urbanization strategy. Poyang Lake Ecological Economic Zone, as one of the key development zones in the main functional areas of our country, is in the stage of rapid development of urbanization, how to correct the direction in the process of rapid development of urban and rural land use mode transformation. The rational optimization of urban and rural land use scale structure and spatial distribution is an important proposition in Poyang Lake ecological economic zone from rapid urbanization to new urbanization. This paper firstly combs the development course of urbanization in Poyang Lake Ecological Economic Zone since the founding of the people's Republic of China, and puts forward the relationship between urban and rural land use and urbanization. The study area is divided into eight directions, and the spatial and temporal patterns of urban and rural land use are analyzed. The analysis shows that the utilization status and growth level of urban and rural construction point to the southwest direction, that is, Nanchang, Xinyu. It shows that whether the size of the city or the growth rate of development, the ranking is still the largest Nanchang metropolitan area. After analyzing the economic development and characteristic industries in various towns and villages, it is concluded that the optimization of the urban and rural system pattern, combined with the pattern of urban and rural construction land, should develop local characteristic industries and rationally distribute the urban and rural land use space. To maximize the land use efficiency, the urban and rural land use pattern has the power of sustainable development in the new urbanization process. Secondly, from the view of population, society and economy, this paper probes into the driving force of urban and rural construction land expansion, and explores the key factors to drive urban and rural expansion. The driving force model of urban and rural construction land expansion was established by using grey correlation degree method, and the 32 evaluation units of Poyang Lake Ecological Economic Zone were analyzed for urban and rural construction land expansion from 2005 to 2010. Eight economic and social development factors affecting urban and rural construction land expansion in the study area were analyzed and sorted, and the main driving forces of urban and rural construction land expansion in the study area were obtained. It is concluded that the driving force of urban industrial and mining land expansion comes from the level of social industrialization and economic development. The driving force of rural residential expansion comes from farmers' per capita occupation of cultivated land, income level of rural population and agricultural production level. Finally, using niche suitability model, the evaluation system of niche suitability is constructed, which includes four categories of indicators, including commercial development, industrial development, agricultural development and environmental protection. The ecological economic zone of Poyang Lake is divided into five types: the leading area of commercial development, the leading area of industrial development, the leading area of agricultural development, the leading area of environmental protection and the forbidden zone. Combined with the main function area construction goal and its zoning results, the spatial layout of urban and rural land use in Poyang Lake Ecological Economic Zone was optimized. The comprehensive zoning results of Poyang Lake Eco-Economic Zone are divided into core growth pole, regional center, primary diffusion circle, secondary diffusion zone, secondary diffusion zone and forbidden diffusion zone. Based on the results of comprehensive zoning of land use and on the basis of niche suitability model, the optimal balance model of urban and rural land use structure was put forward, and the structure of urban and rural construction land in the study area was optimized. According to the results of optimizing the structure and layout of urban and rural construction land, the paper puts forward some suggestions on the policy of urban and rural area difference land use.
