摘　　要：为了探究萍乡市路网形态对住宅用地价格的影响,以2011-2020年萍乡市中心城区出让住宅地价样点为例,基于空间设计网络分析(sDNA)模型和多尺度地理加权回归(MGWR)模型探究路网形态对住宅用地价格的多尺度关系。结果表明,2011年以来,萍乡市住宅空间分布呈现轴向发展、向内填充与向外扩散并进、多中心圈层结构相融合的演化趋势;路网形态总体呈现块状聚集,轴向延伸的空间格局;路网接近度对住宅用地价格呈现出正向的城区边缘高,中心区低的空间格局,密度、穿行度与之相反,同时出现跨尺度相似性。研究成果可为市政完善土地市场价格管理体系提供科学的决策依据,同时为城市交通规划以及房地产选址布局提供相关建议。Taking the selling of residential land at transfer prices in the central city of Pingxiang City from 2011 to 2020 as a sample,the sDNA and MGWR models were used to explore the multi-scale relationship between road network form and residential land price.The results show that the spatial distribution of residential areas in Pingxiang City has shown a trend of outward diffusion and inward filling since 2011.The integration of axial development and multi-center circle diffusion is obvious.The overall shape of the road network presents as a spatial pattern of“mass gathering and axial extension”.The effects of the road network proximity on residential land price show a spatial pattern of“high at the urban edge and low in the central area”,while the density and penetration are the opposite,exhibiting a cross-scale similarity.The study can benefit scientific decision-making for the government to improve the land market price management,and provide references for urban transportation planning and real estate site selection.
