| 摘要: |
| 为综合分析影响农村居民点布局的各项因素，以余江县农村居民点为研究对象，对农村居民点综合影响力进行评价，结合核密度分析得出农村居民点的集聚性，并提出了农村居民点的4种优化方案，最后引入加权Voronoi图，以确定农村居民点的搬迁方向。研究表明：余江县综合影响力一级、二级和三级农村居民点面积分别为2 472.54、3 173.01和977.26 hm2，面积占比依次为37.33%、47.91%和14.76%，高级别农村居民点主要分布在余江县综合条件优越的中部区域，低级别的农村居民点主要分布在北部丘陵区域；核密度分析结果直观显示了高集聚区的农村居民点主要分布在中部平原区域，可优先发展；农村居民点布局优化方案中，就近城镇化型农村居民点共1 116.99 hm2，重点发展型农村居民点共2 839.37 hm2，内部挖潜型农村居民点共2 126.93 hm2，迁移归并型农村居民点共539.52 hm2，综合条件较差的南北丘陵地带设置的迁移安置点较少。研究结果可为对低丘岗地区农村居民点的科学规划与布局优化提供参考，并可运用到土地整治规划、村镇规划和土地利用总体规划中。 |

| Abstract: |
| Taking rural residential settlements in Yujiang County as study object,factors affecting rural residential layout are comprehensively analyzed and evaluated.The clustering pattern of rural settlements is investigated by kernel density estimation.Four optimization schemes were proposed based on the above research.Weighted Voronoi diagram was introduced to determine the rural residential moving direction.The results show that:the comprehensive influential factors of rural residential are divided into three levels (level 1,2 and 3);The rural residential area of three levels are 2 472.54,3 173.01 and 977.26 hectares,accounting for 37.33%,47.91% and 14.76%,respectively;Rural residential of high-level is mainly distributed in central area of Yujiang County,whose condition is superior,and rural residential of low-level are mainly distributed in the northern hilly region;Kernel density analysis results intuitively display that high concentration of rural residential are mainly distributed in central plains area,giving priority to development.Considering rural residential layout optimization scheme,there are 1 116.99 hectares rural residential of urbanization;2 839.37 hectares rural residential which given priority to development;2 126.93 hectares of rural residential has internal developing potential;539.52 hectares of migration and merge rural residential,and in the north and south hilly terrain with poor general condition,a few migration sites were set up.The results of our research provides significant reference for the scientific planning and layout of rural residential in the low-hilly region,and can be applied to land renovation,village and general land use planning. |
