- 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 was guaranteed that land use function zoning and spatial layout optimization is an important way to achieve the integration in the process of urban and rural development. The Poyang Lake ecological economic zone was taken as an example， and then the ecological niche suitability model of urban and rural land use, the land use niche suitability of Poyang Lake ecological economic zone was partitioned, and the optimal placement strategy was proposed. The results show that: (1) it was suggested that the layout optimization for the commercial development of the leading areas, industrial development and agricultural development of the leading areas, environmental protection and the development zone and other areas of the prohibition in Poyang Lake eco-economic zone; (2) it was divided into the core growth pole, the regional central city, the first-level diffusion circle, the two-stage diffusion circle and the two-stage diffusion zone in order to optimize the spatial layout of urban and rural land use ecological economic zone of Poyang Lake; (3) it also shows that urban and rural land use spatial layout optimization should be resulted from the development of high-tech industries, enhancement of the core competitiveness of metropolitan area, demand of urban and rural security, acceleration of the farmland water conservancy construction and optimization of the ecological development utilization model. It was concluded that the study of land use distribution in urban and rural areas can provide a new perspective to realize the balanced development between urban and rural areas based on the ecological suitability model.
