基于引力模型的城乡交错带空间边界界定研究
|
摘要
以海口市为研究区域,利用海口市2012年landsat数据以及海口市2012年统计年鉴,应用引力模型,选择人口密度、农业用地比重、建设用地比重、景观多样性4个指标构建城乡交错带边界界定的指标体系,基于公里网格展开分析,界定城乡交错带的边界。研究结果表明:(1)由城市核心区到外围腹地,引力值逐渐减少,引力值二次变化率存在断点。(2)海口市城乡交错带的内边界出现在距离城市中心10 km左右处,外边界的形状呈长心形,离中心点最远处出现在距离城市中心35 km的地方;城乡交错带外边界最北与海口市行政界线一致,最东到达了三江镇,南部更是涵盖了旧州镇大部分区域,西部到达了石山镇。城乡交错带空间范围的确定对促进海口市的城乡协调发展、制定合理的城市发展规划、实现土地资源的科学、高效利用具有重要的意义。
Urban-rural fringe is the most violent area of urban land use change,As urban space to expand the scope of urban-rural fringe is also constantly changing.Using the Landsat data of Haikou city in 2012 combined with the Haikou city 2012 statistical yearbook,the gravity model as the foundation,Choose population density,the proportion of agricultural land, the proportion of construction land,landscape diversity to construct the index system to defining the boundary of urban and rural fringe. To determine the scope of Urban-rural fringe space has a great significance to reasonable development planning, promote urban and rural areas, to achieve land of scientific, rational and efficient use, building a socialist harmonious society.The results show:(1) From urban core to rural area,the gravity value decreases, the secondary value of the rate of change of gravity has a break.(2) The inner boundaries of Haikou city's urbanrural fringe is at a distance of 10 kilometers from the city center,the shape of the outer boundary is like a long heart-shaped.The most distant from the center of the outer boundary occurred in the 35 kilometers.The most northern of Urban-rural fringe's outer boundary line with administrative boundary of Haikou city, the most easterly reach the Sanjiang Township, the southern part is covering much of Jiuzhou Township and Sanmenpo Township and the western reached Shishan Township.
