摘要
城镇化是一个人类社会活动及生产要素从农村地区向城镇地区转移的过程。其结果,现代城镇成为了人类社会的生活、生产、消费和污染集聚之地。根据生态系统法则的演绎,城镇的资源环境消费或占用是通过直接、间接和诱发三种方式来实现的。重要的问题在于,现代城镇的资源环境消费或占用是按照直接<间接<诱发的形式排列,从而构成了与自然生态系统相左的倒"金字塔"型结构特征。在这种倒"金字塔"型消费和占用结构的作用下,现代城镇发育的资源环境基础不仅在于城镇所在区域,而且也在于整个国家、乃至全球。
Urbanization can be referred to as a process by which both human activities and productive factors concentrated from rural areas to urban areas.As a result,modern cities play a role as the central places for human-being,not only in settlements and material consumptions,but also in social productions and environmental pollutions.In terms of the law of ecological evolution,the behaviors of cities in consumption or occupations of natural resources and environment are also composed with the three types: namely,the direct,the indirect and the induced.More importantly,however,such behaviors are proved in a pattern formatted by the direct the indirect the induced according to city's material use and environmental input,which can be libeled as an inversed-pyramid structure compared with the pyramid structure for the natural eco-system.Under this circumstance,the resource-environment foundation for the development of modern cities is far beyond the boundaries of the cities themselves,and the regions or even the countries where the cities are located.
