Innovations in Constructing the Framework of China's Environmental Code——Referencing the Framework of China's Civil Code

The success in compiling China's Civil Code benefits from factors such as China's complete system of civil law statutes,the methodology of the Pandekten System,and the private-law attributes of civil laws,etc.To construct the framework of China's environmental code,it is necessary to reference that success for theoretical and structural innovations.In addition,the fundamental features and inherent issues of China's existing environmental law system,such as its breadth,the extensiveness of origins of environmental law,the multiple implication of environmental legal relations,and the compound nature of the environmental legal liability system,should be taken into account.The layout structure of"General-Specifics"should be adopted for compiling China's environmental code,while moderate codification and extraction of the common factor(vor die Klammer zu ziehen)for connection with applicable rules of specific laws should serve as construction principles and methods for compiling the framework of China's environmental code.The environmental code should have five parts:"General";"Pollution Prevention and Control";"Nature Conservation";"Green and Low-Carbon Development";and"Ecological and Environmental Responsibility."

Carbon Emission Evaluation in Jinan Western New District based on Multi-source Data Fusion

Carbon emissions caused by human activities are closely related to the process of urbanization,and urban land utilization,function vitality and traffic systems are three important factors that may influence the emission levels.For clarifying the space structure of a low-carbon eco-city,and combining the concept of"Combining Assessment with Construction"to track and contrast the construction of the low-carbon eco-city,this research selects quantifiable low-carbon eco-city spatial characteristics as indicators,and evaluates and analyzes the potential carbon emissions.Taking the Jinan Western New District as an example,diversity of construction land,travel carbon emission potential,and density and accessibility of adjacent road networks in the overall urban planning were measured.After the completion of the new urban area,the evaluation mainly reflected certain factors,such as the mixed degree of urban functions,the density of urban functions,the walking distance to bus stops and the density and number of bus stops.Dividing the levels and adding equal weights after index normalization,the carbon emission potential is evaluated at the two levels of the overall and fragmented areas.The results show that:(1)The low-carbon emission potential areas in the planning scheme basically reached the planned goals.(2)There is inconsistency between districts and indicators in the planning scheme.The diversity of construction land and the accessibility of the adjacent road network are relatively small;however,there is a large difference between the travel carbon emission potential and the road network accessibility.(3)Carbon emission potential after completion did not reach the planned expectation,and the low-carbon emission potential plots were concentrated in the Changqing Old City Area and Central Area of Dangjia Town Area.(4)The carbon emission indicators varied greatly in different areas,and there were serious imbalances in the density of public transportation lines and the mixed degree of urban functions.
