寻求城市可持续发展的生态支撑：城市生态支持系统理论初探

城市是一个复合的生态系统，它必须凭借一定的生态支持维持基本的结构与功能，寻求进一步的发展。城市生态支持系统能为城市提供资源、能源、空间等最基本的支持，并调控城市发展速度、规模与演替方向。在提出这一概念的基础上，初步探讨了城市生态支持系统所具有的人工与自然的双重特征及其研究的内容，包括有城市人口、资源、能源、环境、边缘系统、绿地、空间结构等诸多方面。

Seeking Ecological Supporting on Urban Sustainable Development Theories on Urban Ecological Supporting System

Urban is a combined ecosystem that needs to rely on ecological supports to maintain it'sstructure and function and seeks further development. Urban ecological supporting system (UESS) af-fords urban the basic supperts such as resources, energy, space, etc. and regulates the speed, scaleand evolving direction of urban development. On the basis of the definition of the UESS, this paperdiscusses the two-fold character and the studying contents of the UESS. The contents include population, resources, energy, environment, edge system, greenland, spatial structure.
