北京市食物发展战略的系统分析

运用大规模系统理论、耗散结构学说和经济地理学等理论剖析北京食物大系统。北京市是一个具有耗散结构的开放系统,所以,它能通过与外界环境的物质和能量(包括各种食物)的交换维持其动态平衡。食物是限制城市发展的制约因素之一。对北京市郊区生态系统分析的结果表明,北京郊区土地最大承载力为12559050人。

Systematic Analysis on Food Development Strategy in Beijing

With applications of several theories(large-scale systems analysis, dissipative structure and economic geography), this paper analyses the large- scale system of food problem in Beijing. Beijing city is an open system with dissipative structure, so it can keep dynamic equilibrium by exchanging materials and energies (including foods) with its surroundings. Food is considered as one of the limiting factors to urban extension. The ecosystem analysis shows that the largest holding capacity of the suburbs in Beijing is 12 559 050 people.
