基于地理空间适宜性指数自相关的农村居民点整理分区
农村居民点整理是提高建设用地节约集约利用水平的重要手段,为研究基于地理空间属性的区域农村居民点差异化整理方向和模式,提高整理效率,该文以甘肃省临夏县北塬地区为例,从农村居民点地理环境、空间区位、空间分布和空间形态4个方面构建居民点整理地理空间适宜性评价指标体系,通过对各指标标准化值加权求和并进行空间自相关分析,获取适宜性程度的空间聚集特征并结合各行政村超标可整理面积进行农村居民点整理分区,针对不同分区特征提出差异化的整理方向和模式。结果表明:1)地理空间适宜性值为32.093-85.226,空间分异明显,指标体系可较好地反映区域农村居民点地理空间属性差异;2)全局Moran指数为0.66,在0...

| Summary: | 农村居民点整理是提高建设用地节约集约利用水平的重要手段,为研究基于地理空间属性的区域农村居民点差异化整理方向和模式,提高整理效率,该文以甘肃省临夏县北塬地区为例,从农村居民点地理环境、空间区位、空间分布和空间形态4个方面构建居民点整理地理空间适宜性评价指标体系,通过对各指标标准化值加权求和并进行空间自相关分析,获取适宜性程度的空间聚集特征并结合各行政村超标可整理面积进行农村居民点整理分区,针对不同分区特征提出差异化的整理方向和模式。结果表明:1)地理空间适宜性值为32.093-85.226,空间分异明显,指标体系可较好地反映区域农村居民点地理空间属性差异;2)全局Moran指数为0.66,在0.01显著水平上极显著,呈显著正空间自相关性,LISA图显示只存在显著高高、低低聚集,与全局分析一致;3)分区划为优先整理区、次级整理区、并点整理区和选择性整理区,包含空间聚集特征,可较好地识别居民点整理适宜性和整理效益差异。研究可为农村居民点整理实践作参考,为农村居民点整理分区研究提供新的思路和方法。 |

| Bibliography: | As an important way, rural residential land consolidation is needed seriously to raise the level of construction land saving and intensive use, to increase the effective area of cultivated land and to achieve the requisition-compensation balance of cultivated land. Consolidation zoning is scientifically and orderly conducive to rural residential land consolidation. Based on geographical spatial properties, in order to study differentiated consolidation directions and modes for regional rural residential land and improve consolidation efficiency, this paper took Beiyuan region of Linxia County in central Gansu Province as an example, administrative village as the study unit and rural residential land as the study object. An evaluation index system based on geographical spatial suitability of rural residential land consolidation was constructed from 4 aspects including geographical environment, spatial location, spatial distribution and spatial pattern based on literature analysis. The comprehensive value of ge |
