摘要:

以农村居民点斑块为研究单元,在分析海棠镇农村居民点斑块综合影响力的基础上,基于不同地貌,制定差异化的空间布局优化策略,并应用加权Voronoi图指导居民点斑块的迁移方向。结果表明:① 海棠镇村级影响力居民点斑块面积183.57 hm2(183个);社级影响力居民点斑块面积206.86 hm2(391个);零星居民点斑块面积31.49 hm2(118个),影响力较大的居民点斑块主要分布在海棠镇中东部地势较平缓的区域;② 通过布局优化,全镇农村居民点斑块总面积从优化前的421.92 hm2减少到优化后的353.73 hm2,减少了16.16%;居民点斑块密度由优化前的14.74个/km2降低到8.94个/km2,降低幅度达39.35%;居民点斑块平均面积从优化前的0.61 hm2增大到0.84 hm2,增加了37.70%。海棠镇农村居民点“小散乱”的空间分布现状得到较大改善。

Abstract:

This paper regards rural residential land patch as a research unit. According to the analysis of comprehensive influence on rural residential land patch in the Haitang country, we design different optimal spatial distribution strategies based on different landforms, and provide migration direction for guiding rural residential land parch by employing the method of Voronoi. The results of this study show the following aspects: (1) the area of 183 rural residential land patches with village-level influence is 183.57 hm2, and the area of 391 rural residential land patches with group-level influence is 183.57 hm2, and the area of 118 scattered settlements is 31.49 hm2; rural residential land patch with greater influence is mainly distributed in the central-eastern part of Haitang county where the terrain is comparably flat. (2) Through layout optimization, the total area of rural residential land patch in the whole county has decreased from 421.92 hm2 to 353.73 hm2 after optimization, or a reduction of 16.16%; and the density of rural residential land patch has decreased by 39.35%, from 14.74 per km2 to 8.84 per km2, and the average area of rural residential land has decreased from 0.61 hm2 to 0.84 hm2, or a reduction of 37.70%. From the above analysis, the scattered spatial distribution of rural residential land in Haitang county has been improved to a certain extent.
