基于变权理论的近零碳排放园区综合评价研究

近零碳排放是低碳排放的进一步深化和落地,是不断趋向于零碳排放的动态过程.以碳的形成生命周期为核心将低碳园区分成智慧型园区和生态型园区,从规划、近零碳技术、碳排放管理、环境健康四个要素出发,同时根据园区的碳排放溯源跟踪体系,形成以能源消耗、工业生产、建筑、交通、废弃物处理、碳汇、碳排放管理、健康生活为准则层的指标体系架构...

Comprehensive evaluation of nearly zero carbon emission parks based on variable weight theory

Near zero carbon emission is the further deepening and landing of low carbon emissions, and it is a dynamic process that tends to zero carbon emissions. This paper divides low-carbon parks into smart parks and ecological parks based on the life cycle of carbon formation. Starting from the four elements of planning, near-zero carbon technology, carbon emission management and environmental health, and according to the traceability tracking system of carbon emissions in the parks, the low-carbon parks are formed with energy consumption, industrial production, construction, transportation and abandonment. The index system structure of material disposal, carbon sink, carbon emission management and healthy life is the criterion level. When the park is in different stages of near zero carbon development, the internal differences of evaluation indicators are also different. Constant weight evaluation method can not reflect the impact of various indicators on near zero carbon development, which will affect the accuracy of the evaluation results. This paper will introduce the variable weight theory and construct a penalty variable weight model. By comparing the results of constant weight evaluation and variable weight evaluation, it can be seen that the evaluation results of variable weight evaluation model are easier to distinguish the development grade. It is verified that the variable weight evaluation method is more suitable for the dynamic characteristics of near zero carbon development.
