物质代谢研究进展综述

传统的线性经济生活模式导致人类社会面临着巨大的环境压力,因此为提高资源的利用效率,实现社会经济的可持续发展,物质代谢研究逐渐成为近年来国际研究领域的热点问题。文章从三方面对国际上关于物质代谢研究进展做了阐述:①物质代谢的研究背景;②物质代谢的基础性研究,包括不同层次的物质代谢吞吐量的研究和物质代谢定量分析方法的探讨;③物质代谢相关的研究进展,包括土地利用/覆盖变化、自然环境效应和可持续发展与物质代谢作用关系的讨论。最后,对其未来的发展方向提出了一些建议,认为除了要进一步完善物质代谢研究方法和模型外,还应从土地利用/覆盖变化、研究尺度、政策和行为、生态环境效应等角度对物质代谢进行拓展分析。

Review on the Research of Metabolism

Enormous pressure on environment was given by the traditional linear living pattern.Recently,for improving the efficiency of using resources and achieving sustainable development,study on socio-economic metabolism has increasingly become the focus problem in science field.This paper discussed the international research about socio-economic metabolism in three parts.The research background of socio-economic metabolism was presented firstly.In this part,the differences among material flow,resources flow or metabolism were pointed out.Study on material flow focused on the character about material flowing process in specified region.However,it ignored the relationship among each part the process.Resources flow research emphasized efficiency of using resources by the analysis on internal alternative process.Whereas,metabolism put much attention on the material amount out and in socio-economic system,the environmental effect taken by the material.Then,the basic study on socio-economic metabolism was given.This part contained study on metabolism throughput in different levels and quantitative analysis about metabolism.The throughput was mainly divided into 3 levels,they were national,regional and familial.In the rough,there were four ways to analyse socio-economic metabolism.They were MFA(Material flow analysis),EFA(Energy flow analysis),HANPP(Human appropriation of net primary production)and ecological footprint.Thirdly,correlative researches of metabolism were pointed out,there were relations among metabolism and land use and land cover change(LUCC),environmental effect,and sustainable development.Lastly,some advices were put forward.Besides making the research ways perfectly,the main respect was to go deep into the analysis between metabolism and LUCC.Especially,study on socio-economic metabolism's driving function to LUCC should be intensified.And some researches on the feedback mechanism among policy,behavior and metabolism were urgently needed.Sensitive region in the ecosystem should be taken account of metabolism.Especially,environmental effect taken by metabolism should be intensified.Some factors related to socio-economic metabolism could be taken into account in the appraisal of sustainable development and recycling economy.
