以镇江市丘陵区的乡村聚落为研究对象,利用景观格局分析方法和GIS空间分析方法,探讨镇江市丘陵区乡村聚落空间格局特征及其影响因素。结果表明:镇江市乡村聚落空间格局呈现出十分显著的东西分异特征,整体上镇江市东部地区的乡村聚落规模小、空间分布密集、聚落形态较为规则;而中西部地区乡村聚落规模大,空间分布稀疏,且聚落形态较破碎;镇江市乡村聚落空间格局受地形、经济、交通、水系、耕地分布等因素的影响较大,聚落分布具有低海拔区位取向;经济发达区的乡村聚落景观斑块面积小,但斑块密度大,而经济欠发达区的乡村聚落景观斑块面积大,但斑块密度小;乡村聚落距离道路500m及水系1 000m的区域内空间分布最为密集;同时乡村聚落与耕地空间分布具有显著的趋同性规律。
Rural settlements are the places of habitation,production and the living for people.In this paper,through landscape pattern analysis and GIS spatial analysis methods,the spatial pattern characteristics and influencing factors of rural settlements in Zhenjiang of Jiangsu Province were analyzed.Some conclusions are drawn as follows.Spatial pattern of rural settlements in Zhenjiang showed an east-west differentiation.In the east region of Zhenjiang,rural settlements pattern presented the characteristic of small scale,dense distribution and regular morphology.Meanwhile,in the west region of Zhenjiang,rural settlements pattern presented the characteristic of large scale,sparse distribution and broken morphology.Influencing factors of rural settlements spatial pattern included terrain,economic,traffic,water system,and the distance of cultivated land.Through the analysis,settlement distribution had low altitude location orientation.Rural settlements plaques area of economic developed region was small,plaques density was large,but in the undeveloped region,rural settlements plaques area was great,plaques density was small.Rural settlements spatial distribution was most densely populated in the area away road at a distance of 500 meters and away water system at a distance of 1 000 meters.Rural settlements and cultivated lands spatial distribution had significant convergence.Currently,rural geography was a weak branch of human geography,especially with regard to theoretical development and the empirical research.This paper took Zhenjiang for example,analyzed spatial pattern and influencing factors of rural settlements,which not only could enrich rural settlement geography theory research,but also could provide the reference of rural settlements planning in Zhenjiang hilly area.
