摘要
村庄空间格局与区域自然、经济、社会因素密切相关,研究村庄空间分布及影响规律对于城乡聚落布局优化和城乡融合发展具有重要的参考价值。以空间信息技术为支持,综合核密度、分离度指数及缓冲区分析等方法对徐州市近郊村庄空间分布及影响因素进行研究。结果表明:(1)研究区东北和北部村庄分布密度大分离度高,而东部和东南部村庄分布密度小但分离度低;(2)研究区内大部分村庄布局在距河流水系2km、海拔小于50m、坡度小于15°的区域内,且随着距道路交通和耕地的距离的增加,村庄分布逐渐减少;(3)道路交通、耕地、河流水系、坡度是村庄分布的关键影响因子。该研究结果揭示了研究区村庄空间分布格局及影响机理,可为乡村地区国土空间优化与重构提供参考,也可为其他地区开展类似研究提供借鉴。
The spatial pattern of villages is closely related to regional natural and economic and social factors.The study of spatial distribution and influencing law of villages has important reference value for the optimization of ur⁃ban-rural settlement layout and urban-rural integration development.Based on spatial information technology,the spatial distribution and influencing factors of suburban villages in Xuzhou were studied by using kernel density,sepa⁃ration index and buffer zone analysis.The results indicate that:(1)most of the villages in north-eastern and northern area show high feature in the density and separation,while eastern and south-eastern area low;(2)the majority of vil⁃lages are in the areas with the distance to river less than 2km,the elevation less than 50m and the slope less than 15°,and the number of villages decreases along with increase of the distances to road or arable land patches;(3)transpor⁃tation,arable land,river and slope are the key influencing factors of village distribution.Our study explores the spa⁃tial feature of village location and their influencing mechanism,it can provide reference for the reconstruction and op⁃timization of village layout.
