摘要: 【目的】基于遥感数据和3S技术进行乡村聚落时空分布特征及演变规律研究,为推进美丽乡村建设和实现地区可持续发展提供参考。【方法】以安徽省黟县为对象,基于核密度分析、GIS空间分析、景观格局指数以及空间自相关等分析方法,探究研究区2010年、2012年、2014年、2016年4年乡村聚落的时空分布特征与景观格局变化的驱动因素。【结果】2010年与2012年黟县各村镇之间的乡村聚落核密度估值呈较弱的聚集分布,2014年与2016年黟县各村镇之间的乡村聚落核密度估值呈显著的聚集分布状态; 2010年、2012年、2014年、2016年的Moran's I指数均大于0,黟县乡村聚落存在正的空间相关性,2016年Moran's I指数较2014年的低; 黟县乡村聚落核密度估计值相似的地区在空间上聚集分布的趋势有所减弱,空间分布的差异性在增强; 地势、河流等自然因素以及道路、城镇经济、人口变化等社会因素影响黟县乡村聚落分布格局的演变。【结论】黟县乡村聚落的时空分布格局特征与演变研究能够为美丽乡村建设中的合理规划、聚落优化、土地资源利用以及可持续发展规划建设提供理论依据。

Abstract: 【Objective】Based on remote sensing data and 3S technology, studing on the spatial and temporal distribution characteristics and evolution of rural settlements provide guidance for promoting the development of beautiful countryside and realizing regional sustainable development.【Method】The spatial and temporal distribution of rural settlements in Yixian County and the driving factors of landscape pattern change across four years were analyzed based on the principle of the kernel density estimation, GIS spatial analysis, landscape pattern index and spatial autocorrelation analysis.【Result】The rural settlements' kernel density estimation of villages and towns in Yixian was weakly aggregated in 2010 and 2012. Meanwhile, the kernel density estimation showed a significant aggregation distribution in 2014 and 2016. In 2010, 2012, 2014 and 2016, the Moran's I index was greater than 0. There was positive spatial correlation in the rural settlements of Yixian. In 2016, Moran's I index was lower than that in 2014, which showed that the trend of agglomeration and distribution in space was diminished and that the difference in spatial distribution increased in the regions with similar kernel density estimates. Lastly, natural factors such as topography, rivers and other social factors as well as roads, town-economies and population change are the driving factors of the changes in the distribution characteristics of rural settlements in Yixian County.【Conclusion】The study on the characteristics and evolution of the temporal and spatial distribution patterns of rural settlements in Yixian can provide an effective basis for rational planning, settlement optimization, land resource utilization and sustainable development in planning the construction of beautiful villages.
