湖北省国土空间碳排放格局特征与优化对策

Characteristics of Carbon Emission Pattern in Hubei Territorial Space and Its Improvement Measures

土地利用变化作为影响全球气候变化和碳循环的重要因素,不仅会改变地表的自然碳过程,还会通过改变人类能源消耗强度来影响碳循环的速率。文章基于湖北省的土地利用测算碳源或碳汇总量,通过测算碳源经济贡献系数和碳汇生态承载系数,将省域空间划分为碳排放低碳发展区、碳强度控制区、碳汇功能区和高碳优化区。在分析区域存在的经济贡献度与生态承载度不匹配、经济贡献度与空间结构性不协调、生态产品价值实现的机制不完善、资源配置与区域功能关系不和谐等诸多问题的基础上,为进一步提高湖北省碳排放治理水平,文章提出了“依托分区特征,完善空间碳排放格局;联接功能结构,实现资源的有效配置;强化政府与市场的作用,完善生态价值机制;缓和结构矛盾,协调经济与生态贡献”的碳排放优化策略。

The change of land use may impact the natural carbon process of earth surface,and also influence carbon circulation based on energy consumption.With a calculation of general carbon source and carbon sink based on land use of Hubei province,and a calculation of carbon sourced economy contribution coefficient and carbon sink ecological carrying capacity coefficient,the author divides the provincial space into low carbon development area,carbon intensity control area,carbon sink area,and high carbon optimization area.Based on an analysis of the regional problems such as mismatch between economic contribution and ecological carrying capacity,structural incompatibility between economic contribution and space,incomplete mechanism in ecological product value realization,discordant relationship between resource configuration and regional function,carbon emission improvement strategies are proposed:integrating carbon emission space pattern based on zoning characters,realizing efficient configuration of resources for functional connection,improving ecological value mechanism by government and market measures,coordinating economic development and ecological contribution by mediation of structural contradiction.
