摘要
合理分析农村居民点分布情况及驱动因素对城乡治理及乡村振兴具有重要意义.结合核密度分析、标准差椭圆和Pearson相关分析等方法对南京市2000~2020年农村居民点密度时空分布及驱动因素进行探究.结果表明:2000~2020年农村居民点主要向东南方向偏移,偏移强度2000~2010年大于2010~2020年;在500 m、1000 m和1500 m网格尺度下,归一化建筑物指数(NDBI)在2000年对农村居民点的影响最大,归一化植被指数(NDVI)在2010和2020年对农村居民点的影响最大.建议科学配置土地利用空间,合理布局农村居民点,以实现人类与自然和谐共生.
Reasonable analysis on the distribution of rural residential areas and driving factors is of great significance for urban and rural governance and rural revitalization.Combined with the kernel density analysis,standard deviation ellipse,Pearson correlation analysis and other methods,the spatio-temporal distribution of rural residential areas density and the driving factors in Nanjing were explored from 2000 to 2020.The results showed that the rural residential areas mainly migrated to the southeast from 2000 to 2020,and the migration intensity during 2000 to 2010 was greater than that during 2010 to 2020;at the grid scales of 500m,1000m and 1500m,the Normalized Building Index(NDBI)had the greatest impact on rural residential areas in 2000,and the Normalized Vegetation Index(NDVI)had the greatest impact on rural residential areas in 2010 and 2020.It is suggested that land use space should be allocated scientifically and rural residential areas should be distributed reasonably so as to realize the harmonious coexistence of human and nature.
