杭州市自行车租还潮汐与街区用地模式关系研究

District-level Land Use Pattern Based on Pickup-return Tide of Bicycle Rental System in Hangzhou

文章利用杭州主城区的公共自行车租赁点数据,首先分析了单一租赁点的租还潮汐特征、空间聚类特征;其次,结合街区尺度的用地结构指标,考察了服务区单元的单点潮汐比与居住用地比例、用地复合度的关系,以及功能区块的多点潮汐指数与用地构成及其空间组织的关系。研究发现,自行车租还潮汐指数能够有效反映不同街区的用地结构模式及其差异,可作为精细化判别街区用地结构问题的探针工具,并指出以杭州老城区为典型案例的自平衡街区模式有利于自行车等交通潮汐的源头控制,对于街区复合开发策略的制定有借鉴价值。最后,文章探讨了自行车潮汐指数在运力调度优化、慢行交通"微"治理、用地功能靶向修复和规划方案评价等方面的若干应用场景。

Firstly,the pickup-return tide of bicycle rental stations and their spatial cluster characteristics is analyzed based on rental big data of Hangzhou Central city.Then,combined with certain land use structure indicators at district level,not only the relationship between the tidal ratio and residential land proportion as well as land use diversity for single-stationed service areas,but also the relationship between the tide and the land use composition with its spatial layout for the multi-stationed functional zone are investigated.It is found that the bicycle tide index can effectively re flect the land use structure patterns and their differences in different districts,and it can be used as a probe tool to identify the problems of land use structure in the districts.It is pointed out that the self-balanced district model such as Hangzhou Old Town is bene ficial to the source control of rental tide and has reference value for making strategies of mixed-use development at district scale.Finally,several applications of bicycle tide index such as capacity dispatching optimization,pedestrian and non-motorized mobility re finement,targeted land use amelioration and planning scheme evaluation are discussed.
