摘要:

开展城市土地承载力研究既是对土地承载力研究体系的深化,也是对城市持续发展的有益探索.总结城市土地承载力研究的起源、发展、内容、方法以及在相关领域的应用,发现其多出自于城市规划、土地利用、资源环境、生态系统等领域的延伸,或为某一领域的一部分,而其自身的研究体系尚未形成.已有研究主要从承载主体、承载对象和影响因素3个视角探讨了与城市土地承载力相关的内容,重在分析和评价城市各类土地与人口规模、经济增长、社会发展以及生态环境之间的关系.在研究方法上,数理分析、模型方法、指标体系等被普遍采用,但各评价方法根据评价对象和城市特点有所不同,评估结果在很大的程度上依赖于选择的不同方法,从而使得到的结果之间缺乏可比性.在实践层面,城市土地承载力分析的实际应用还很薄弱,但其指导作用已经凸现.研究认为,城市土地承载力从基本概念到量化方法、再到实践应用的研究中还存在不足之处,今后的研究应当侧重于完善城市土地承载力自身的研究体系,并结合社会发展需求进行城市土地承载力的功能分区研究和预警研究,建立城市土地承载力状态与土地政策调控的互动机制,逐步加强研究方法的更新和研究成果的应用推广.

Abstract:

Research on urban land carrying capacity(ULCC) is not only a progress in traditional land carrying capacity(LCC), but also a useful tool to explore the sustainable development of cities. As it is concerned by an increasing number of experts, this paper reviews the origin, development, contents and methods of ULCC, as well as its application in city management. ULCC focuses on city areas, so its research changes the previous “land-food-population” direction in land carrying capacity, and emphasizes the all-together analysis of population size, economic growth and social development which the city can support. References show that ULCC was talked frequently in fields such as urban development, resources, environment and ecosystem. But, the system of ULCC itself has not been formed yet. Classification of the related literatures shows that the existed studies mainly discussed something related to ULCC independently from three perspectives, such as carriers, objects and influencing factors. They aim at relationship analysis between different kinds of urban land and population, economic growth, social development and eco-environment. Almost all of the existed papers made a lot of quantitative analysis to answer how many citizens, and what kind of economy and lives the urban land can support. Although methods used in these papers cover mainly mathematics, model, and indicator system, they are different for different objects and urban features. So, it destroys the possibility of comparing the evaluation results among different cities. Furthermore, the effects of ULCC used for urban land management were mostly unsatisfactory. In view of the current research shortcomings, it is pointed out in the end that something should be done in the future to improve the research system of ULCC itself, to identify main function zoning of urban land based on ULCC, to strengthen early warning study of ULCC, to set up interactive mechanism between ULCC evaluation and land use policy, and to renew methods and popularize the research results.
