摘要
研究农村居民点的分布及影响因素可以实现土地节约集约利用,为城镇化建设提供依据,并促进乡村振兴战略的顺利实施。运用平均最近邻指数、核密度分析结合景观指数法分析阆中市农村居民点的空间分布特征及演变规律,并研究高程和坡度因素对农村居民点分布的影响。结果表明:(1)在快速城镇化背景下,阆中市农村居民点规模扩张明显,集约用地程度较低,斑块空间分布聚集特征进一步加强,居民点斑块形态趋于复杂,斑块间差异显著,破碎度高,存在较大的整治优化空间;(2)阆中市农村居民点近十年整体空间格局变化不大,只是局部集中趋势进一步增强,农村居民点分布格局受高程和坡度影响。
The study of distribution and influencing factors of rural settlements provides a basis for intensive and economical utilization of land,urbanization,and smooth implement of rural revitalization strategy.The spatial distribution characteristics and evolution rule of rural settlements in Langzhong city are analyzed by average nearest neighbor index,kernel density analysis and landscape index method,and the effects of elevation and slope factors on the distribution of rural settlements are studied as well.The results show as follows:(1)Against the background of rapid urbanization,the rural residential area with less intensive land use in Langzhong city has expanded significantly;the spatial distribution and aggregation characteristics of plaques have been further enhanced;the pattern of plaques in rural settlement is becoming more complicated and differs significantly from each other;the degree of crushing is high,leaving a large room for improvement and optimization.(2)The overall spatial pattern of rural settlements in Langzhong city has not changed much in the past 10 years,but the local concentration trend has been further strengthened;the distribution pattern of rural settlements is affected by elevation and slope.
