摘要
选取四川省广汉市为研究区域,运用GIS空间分析方法,定量识别广汉市宜居性空间特征和规律,并以此为依据对其乡村聚落进行空间重构。结果表明:①广汉市县域宜居性呈现以中心城区为高值中心,各乡镇场镇为副高值中心的圈层状分布态势。其中,生活保障功能呈现由中部向四周成圈层状递减态势,生活改善功能呈现分别以中心城区和各乡镇场镇为高值中心向外递减的两类特征,乡风净化功能呈现以中心城区为高值中心向西北和东南方向扩散递减态势。②广汉市乡村聚落空间格局可优化为城郊融合型、聚集提升型、特色发展型、撤并重组型。③川西平原乡村聚落的整治建设和保护规划仍存在总体规划布局单一化、同质化等缺陷,阻碍了川西平原传统文化延续和新农村人居环境改善。
Taking Guanghan City in Sichuan Province as an example,this paper employed spatial analysis in GIS to identify quantitatively the spatial characteristics and rule of livability for reconstructing its rural settlements.The results showed that:(1)The livability of counties pre sented a ring-shaped distribution situation with the central urban areas as the high value center and the towns as the sub-high value centers in Guanghan City.The function of life security presented a gradual downward trend from the center to the surroundings.The function of life im provement presented a gradual downward from the central urban areas and towns as high-value centers to the outside.The function of air puri fication shows a trend of declining diffusion towards the northwest and southeast with the central urban areas as the high value center.(2)The spatial pattern of rural settlements in Guanghan City could be optimized as four types:suburban integration,aggregation and enhancement,char acteristic development,merger and reorganization.(3)There were still some defects in the planning of renovation,construction and protection of rural settlements in the Western Sichuan Plain,such as the simplification and homogeneity of the overall planning layout,which hindered the continuation of traditional culture and the improvement of new rural living environment.
