城市低碳发展的研究框架和理论体系

低碳城市作为一个整体系统，其研究框架可从空间、时间和功能三个维度来展开。涵盖经济和社会两个方面的城市系统，下含生产和生活两个子系统。自然资源、能源是城市系统的输入部分，环境、排放是城市系统的输出部分。城市低碳发展理论体系的研究具体包括：系统的结构和功能特征，系统的空间性、地方性和全球性，城市综合碳循环模型体系，自然与人为双重影响的碳代谢过程，不同空间尺度的城市碳排放和控制，城市过去、现在和未来的碳排放清单与减排路径分析，切实可行的碳管理措施，城市低碳发展的方法论和技术支撑体系。

Research Framework and Theoretical System of Low Carbon Urban Development

Urban low carbon development is a huge,complex but open theory and practical system,thus;a research framework and theoretical system from the perspective of system theory is established.Low carbon urban,as a whole system,can be studied from three dimensions of space,time and function.Economic and social natural resources and energy are the input of urban systems as well as environment and emissions is the output.The research of theoretical system of low-carbon urban development in the future should be rich in the following aspects: such as: the structural system and functional characteristics,space system,locality and globalize,city’s comprehensive model system of carbon cycle,carbon metabolism process of double impact between nature and man-made,urban carbon emissions and control at different spatial scales,the past,present and future carbon emission inventories and emission reduction path analysis,practical carbon management measures,as well as the methodology of low-carbon urban development and technical support system.
