基于城市空间溢出的远郊型乡镇开发模式研究

在城市空间溢出理论的指导下,以我国在2007年设立的国家级统筹城乡综合配套改革试验区重庆市为例,选取重庆市的远郊型城镇江北区五宝镇为研究区域,探讨旨在促进大城市周边的远郊型城镇与城区功能协调、互惠多赢的开发模式。首先,以鲜菜类和休闲度假类消费需求为例,对重庆市主城区城市居民消费需求的空间溢出展开调研;然后,从区位交通、资源基础、生态环境和开发现状等方面分析和判断五宝镇是否具备承接主城区溢出消费需求的条件,并设计了基于城市空间溢出的开发模式;最后,从经济效益、社会效益和生态效益等方面,对远郊型乡镇的传统开发模式和基于城市空间溢出的开发模式进行了综合效益比较。主要结论为:①重庆市主城区对其外部空间的土地、生物、景观和环境等要素存在着显著的溢出消费需求;②以城市溢出消费需求为导向,以协调城乡功能为目标,发挥自身的资源优势,将绿色农业与休闲经济有机结合是此类远郊型乡镇开发的最佳模式。

Study on Development Patterns of Exurb Town Based on Urban Spatial Spillovers Theory

Based on urban spatial spillovers theory,this paper takes Chongqing City which is a national urban-rural integration synthetically reform testing district established in 2007 as an example,and selects Chongqing City’s exurb town of Wubao Town in Jiangbei District as the study area.The purpose of this paper is to discuss development patterns which can coordinate functions between city and exurb town.Firstly,this paper takes fresh vegetables and leisure demands as an example,to investigate the consumption demands spatial spillovers of urban residents.Secondly,the paper analyzes and judges whether the Wubao Town can undertake the spatial spillovers of the main districts of Chongqing City,from aspects such as location,traffic,resources,ecological environment and development status;then the paper designs the development pattern of exurb town based on the urban spatial spillovers.Finally,comparing the comprehensive benefits between traditional development pattern and the one based on urban spatial spillovers from the economic,social and ecological benefits.The conclusions are as follows: ①Chongqing City has significant spillover consumption demands for land,organism,landscape and environment outside;②currently,the best development pattern for exurb town should be oriented by urban consumption demands,and combine green agriculture with leisure economy based on its resources advantage.Exactly,this development pattern is a comprehensive development system that takes natural landscape and ecological environment protection as a precondition,green agriculture as the foundation,leisure economy as the main profit subject,and coordinating functions between urban and exurb town as the purpose.
