摘要:

为探讨区域生态可持续发展的程度,运用物质流分析方法,对深圳市经济环境系统在1992-2007年期间的物质输入与物质输出的规模进行了动态分析,并将物质强度与物质效率与其他区域的相关研究进行了比较。结果表明:深圳是一个资源外部性依赖很强的地区,区域经济系统的物质输入在2004年出现拐点,物质输出与物质输入具有高相关性,区域物质消耗调控的关键应当从源头上控制物质投入规模;深圳市正处于城市发展的第3个阶段,物质输入强度逐步回落,物质输出强度缓慢上升,城市的发展逐步摆脱对物质的依赖性,但区域生态环境系统的压力依然很大;深圳市资源生产率和环境效率逐渐上升,技术的进步提高了物质的利用效率,区域社会经济系统发展的物质消耗成本和环境污染成本越来越小;深圳市经济系统与生态环境系统的相互作用分为两个阶段,口前区域生态系统正处于由相对可持续发展向绝对可持续发展的转型阶段。

Abstract:

To study the relationship between economic development and environmental pressures of the economic system, the material inputs and outputs of the economic system in Shenzhen City during the period from 1992 to 2007 were calculated and analyzed by the material flow analysis (MFA). The material intensity and material efficiency in Shenzhen were compared with other distrios using the same indicators. The results showed that Shenzhen relied greatly on outside resources and the material inputs of its economic system changed obviously in 2004. The key point for controlling material consumption was to control the amount of material inputs. Shenzhen is on the third stage of city development, and the material inputs go down slowly and the material outputs rise. Shenzhen is getting ride of the reliance on the outside materials step by step but the eeo-environmental system is still under a great pressure. Shenzhen’s resource production efficiency and environment efficiency are improving. The improvement of technology increases the efficiency of material use. So the costs of material consumption and environment pollution are becoming lower and lower. The interaction between economic system and eco-environmental system can be divided into two stages. Shenzhen is now experiencing the transformations from relative sustainable development to absolute sustainable development.
