【摘要】：开展城乡土地利用功能分区和空间布局优化,是促进城乡一体化发展的有效途径。以鄱阳湖生态经济区为例,通过构建城乡土地利用生态位适宜度模型,对鄱阳湖生态经济区土地利用生态位适宜度进行了分区,并在此基础上提出了优化布局策略。结果表明:(1)鄱阳湖生态经济区布局优化为商业发展主导区、工业发展主导区和农业发展主导区以及环境保护主导区;(2)鄱阳湖生态经济区城乡土地利用空间布局可划分为核心增长极、区域中心城市、一级扩散圈、二级扩散圈和二级扩散带;(3)应从发展高新技术产业、提升都市圈核心竞争力、保障城乡用地需求、加快农田水利建设和优化生态开发利用模式等方面优化城乡土地利用空间布局。基于生态适宜度模型探讨城乡土地利用布局,为实现区域城乡均衡发展提供了新视角。
[Abstract]:It is an effective way to promote the development of urban and rural integration by carrying out urban and rural land use function zoning and spatial layout optimization. Taking Poyang Lake Ecological Economic Zone as an example, the land use niche suitability degree of Poyang Lake Ecological Economic Zone is divided by constructing the land use niche suitability model of urban and rural areas, and on the basis of this, the optimal layout strategy is put forward. The results show that the layout of Poyang Lake Ecological Economic Zone is optimized as the leading commercial development area. The spatial distribution of urban and rural land use in Poyang Lake Ecological Economic Zone can be divided into core growth poles, regional central cities, and primary diffusion circles. The secondary diffusion zone and the secondary diffusion zone should develop high-tech industries, enhance the core competitiveness of the metropolitan area, and ensure the demand for urban and rural land. We will speed up the construction of farmland and water conservancy and optimize the ecological development and utilization model to optimize the spatial distribution of urban and rural land use. Based on the ecological suitability model, this paper discusses the urban and rural land use layout, which provides a new perspective for the balanced development of regional urban and rural areas.
