资源型城市城镇低效用地空间格局及其盘活路径研究——以鹤壁市为例

Study on Spatial Pattern and Its Revitalizing Path of Inefficient Urban Land in Resource-Based Cities:a Case study of Hebi City

基于高质量国土空间布局和严格管控“三区三线”背景,挖掘存量建设用地,提高土地节约集约利用度已成为城市土地利用亟待解决的重要问题。本文利用鹤壁市旧城镇、旧厂矿、旧村庄三类城镇低效用地的调查数据,运用核密度和标准差椭圆法定量分析了鹤壁市城镇低效用地的空间格局特征,主要结论如下,(1)城镇低效用地表现出面状集聚、多核心的空间分布特点,其中老城区各低效用地点呈“西北-东南”向,集中分布于A1~A5共5个集聚区,数量相对均匀;新城区则呈“东北-西南”向集中分布于B1~B3共3个集聚区,分布呈“东北多西南少”。(2)鹤壁市低效用地空间格局影响因素主要包括资源型城市产业结构调整、工业企业发展不完善、土地征收相关政策调整三个方面。(3)在盘活路径方面,老城区加强停产煤矿厂房的重新利用,部分废弃的采矿用地复垦为公园绿地,新城区重点发展第三产业为主,以引进土地利用强度高的工业企业为主。

Based on the background of high-quality territorial space distribution and strict control of“Three-zones and Three-lines”,excavating stock construction land and improving the economical and intensive use of land have become important issues to be solved urgently in urban land use.Based on the survey data of inefficient land in old towns,old factories and mines and old villages in Hebi city,using the standard deviation ellipse method and kernel density method,the spatial pattern characteristics of urban inefficient land were analyzed.The results indicated that,(1)the urban inefficient land showed the spatial distribution characteristics with planar agglomeration and multi-core,of which the inefficient land sites in the Old Urban were relatively uniformly distributed with a preferential northwest-southeast orientation,concentrated in five agglomeration areas from A1 to A5;and the inefficient land sites in the New Urban located mainly in northeast areas with a northeast-southwest orientation,concentrated in three agglomeration areas from B1 to B3.(2)The factors affecting the spatial pattern of inefficient landin Hebi mainly include the adjustment of industrial structure in resource-based cities,the imperfect development of industrial enterprises,and the adjustment of land expropriation policies.(3)As to the revitalizing path,it should be strengthened about the reutilization of the closed coal mine workshop and reclaimed some of the abandoned mining areas as green lands of parks in Old Urban.And in the New Urban,it should mainly develop tertiary industries,and the industrial enterprises with high land use intensity should be introduced preferentially.
