物质代谢及其资源环境效应研究进展

从物质代谢的视角研究物质在社会经济系统中的流通过程,不仅能深入理解人类活动与自然环境之间的关系,更有助于实现资源的合理利用和可持续发展.本文在对国内外有关物质代谢的研究方法、在不同空间尺度的应用、资源和环境效应的研究进展进行综述的基础上,较全面的对上述研究中已取得的成果以及尚待完善之处进行总结.物质代谢研究应从过去的单一理论和方法向多学科和方法交叉融合的方向发展,以解决复杂的代谢问题.随着城市在全球生态环境中的重要性日益凸显,应加强传统的代谢研究与地理空间分析的结合,并将人类福祉等评价指标纳入物质代谢的研究范畴,进而从物质代谢的视角提出节约资源、降低环境负荷、提高环境-经济-社会协调发展的可持续管理对策.

Research progress in material metabolism and its effects on resource and environment

Studies on the material throughput in the socioeconomic system from the viewpoint of metabolism is not only important for understanding the relationship between human activities and natural environment, but also helpful for utilizing resources in a reasonable and sustainable manner. Based on the review of the research progress in material metabolism worldwide, which included the methodology, application on different scales, and effects on resource and environment, the state of the art of existing literature and the challenges remained for future studies were summarized systema-tically. The material metabolism research should shift its focus on the single theory and method to the integration of multi-theories and methods so as to address the complex metabolism problems. With the increasingly important role that cities play in global ecological environment, more emphasis should be laid on the combination of traditional metabolism research with spatial analysis, and the incorporation of indicators like human wellbeing into the research scope in city-scale research. By doing so, more actionable and sustainable policies could be designed to conserve resources, mitigate the environmental load, and enhance the coordination among the development in economy, environment and society.
