值得重视的城市蔓延问题

揭示了目前中国城市化过程值得重视的现象城市蔓延。认为城市人口的急剧增加以及居民改善住房条件的需求、经济技术开发区的无序建设、大学建设由城市中心向郊区的扩张等乃是城市蔓延的主要原因。分析了城市蔓延带来的环境问题,指出城市蔓延将导致城市水资源、土地资源和湿地资源的浪费,是城市不可持续发展的主要原因之一。提出了解决城市蔓延问题的相应对策:城市管理者应该转变观念,关注发达国家城市发展过程中提出的“精明增长”和“紧凑型城市”的理论;注意城市发展规划的科学性,并加强城市的环境管理等。

An Important Problem:Urban Sprawl

Reveals a phenomenon that we cannot neglect in the course of urbanization in China: urban sprawl.The causes of urban sprawl are mainly the rapid increase in urban population,residents' demand to improve their lodging conditions,disorderly construction of eco-technological development zones and migration of college campuses from urban districts to suburbs.Analyzes the environmental problems thus caused,which will lead to the waste of the presently deficient urban water,land and marsh resources and become one of the predominant reasons of unsustainable urban development.Some countermeasures are put forward against the urban sprawl: the urban administrators should change their out-of-date ideas and pay more attention to the theories prevailing in developed countries in the process of urbanization,such as smart growth,compact urban development and eco-budget, make urban development planning more scientific,and strengthen urban environment administration.
