摘　　要：随着中国城镇化进程的不断加快,城乡交错带成为城市发展的前沿地带,同时也是城镇快速扩张的重要区域。城镇开发边界划定是“三区三线”划定的重要环节,而城乡交错带的分布研究又是城镇开发边界划定的基础性工作。采用核密度分析的方法,对教育医疗、休闲娱乐、生活设施等方面的POI数据进行处理分析,界定出咸丰县7个镇和1个区工委的城乡交错带范围,从咸丰县城乡交错带的空间分布可辨别出山区城市化扩张的3类典型模式,即带状延伸模式、独立扩展模式和孤立发展模式。研究方法不再局限于行政边界区划的束缚,符合城市发展实际情况,可为城乡交错带景观格局、村庄类型识别与分布等相关研究提供借鉴,对咸丰县城镇开发边界划定及国土空间格局优化具有一定的指导和借鉴意义。With the accelerating process of urbanization in China,the urban-rural ecotone has become the frontier of urban development,and it is also an important area for the rapid expansion of cities and towns.The demarcation of the boundary of urban development is an important link of the three-line(urban development boundaries,permanent basic farmland protection red line,ecological protection red line)and three-area(urban space,agricultural space,ecological space).And the study of urban-rural ecotone is the basic work of the demarcation of the boundary of urban development.By using the method of kernel density analysis,the paper takes the 7 towns and 1 working committee of Xianfeng as the objects of study.From the spatial distribution of urban-rural ecotone in Xianfeng County,three typical modes of urbanization expansion in mountainous areas can be identified:band extension mode,independent expansion mode and isolated development mode.This paper is no longer limited to the constraints of administrative boundary zoning,in line with the actual situation of urban development,can provide reference for urban and rural interlaced landscape pattern,village type identification and distribution and other related research,the development of urban boundary demarcation and national territory space pattern optimization in Xianfeng has a certain guiding and reference significance.
