以北碚区2009年和2014年的土地利用变更数据为基础数据,利用GIS技术、景观格局分析、Voronoi图Cv值,对丘陵区农村居民点布局的影响因子及时空变化特征进行分析;并通过确定农村居民点的区位适宜性,将其划分为不同的整治类型.结果表明:6年来北碚区农村居民点斑块数量及占地面积呈下降趋势,斑块破碎化加剧,土地整治有较大需求;农村居民点的分布有向地势平坦,道路、水源便利,以及靠近中心城区的地区聚集的趋势,且环境因子在不同地形位地区对居民点布局的影响程度不同.地形位指数在3以下,距道路800 m以内,距水源1 000m以内,距中心城区2 500m以内对农村居民点分布影响较大;根据北碚区实际情况,提出包入式发展型、集聚式发展型、控制式发展型和迁弃式发展型4种整治模式.
Based on the data of land use change in Beibei area in 2009 and 2014, using GIS technology, landscape pattern analysis and Cv value of Voronoi diagram, the influencing factors and temporal and spatial variation characteristics of rural residential layout in hilly area were analyzed. The results showed that the number and area of rural residential land patches in Beibei district decreased in the past six years, the patch fragmentation was aggravated and there was a great demand for land remediation . The distribution of rural residential areas has the trend of flat topography, convenient roads and water sources, and the tendency to gather near the central urban area, and the impact of environmental factors on residential layout in different terrain areas is different.The terrain bit index is below 3, Within 800 m from the road, within 1 000 m from the water source, and within 2 500 m from the center city, the distribution of rural residential areas has a greater impact on the distribution of rural residential areas. According to the actual situation in Beibei District, this paper puts forward that the development mode of inclusive development, agglomeration development, controlled development, Abandoned development of four kinds of remediation mode.
