贵阳市碳平衡分区特征研究

The Study of Carbon Balance Zoning Characteristic in Guiyang City

摘要: 在“双碳”战略目标下，碳平衡分区特征是城市生态文明建设的重要依据。目前区域碳平衡计算方法以及碳平衡分区研究已日趋完善，贵州省作为生态文明建设示范区，其碳平衡分区研究鲜有报道。因此，本文以贵阳市为研究对象，计算贵阳市2015年和2020年碳平衡空间特征，并研究了贵阳市碳平衡分区特征。研究结果表明，贵阳市各区县碳排放和碳汇特征区域差异有明显区别，市辖区属碳强度控制区，其碳排放经济贡献率高，但碳吸收生态贡献率过低；清镇市和息烽县属碳收支平衡区，两地碳排放经济贡献率和碳吸收生态贡献率都相对较高；修文县属碳汇功能区，其碳排放经济贡献率较低，而碳吸收生态贡献率较高；开阳县属低碳优化区，碳排放经济贡献率和碳吸收生态贡献率都相对较低，贵阳市碳平衡分区可为贵阳市未来经济和生态发展规划提供科学依据。

Abstract: On the carbon peaking and carbon neutrality goals, carbon balance zoning is an important basis for urban ecological civilization construction. At present, the calculation method of regional carbon balance and the research on carbon balance zoning have become increasingly perfect. As a demonstration area of ecological civilization construction, there are few reports on the research of carbon balance zoning in Guizhou Province. Therefore, we take Guiyang City as the research object, calculate the spatial characteristics of carbon balance in 2015 and 2020, and study the carbon balance zoning characteristics. The results show that the regional differences of carbon emission and carbon sink characteristics are significantly different among all the districts and counties of Guiyang. The municipal district is a carbon intensity control area, which has a high economic con-tribution coefficient of carbon emission, but a low ecological contribution coefficient of carbon sink. Qingzhen County and Xifeng County belong to the carbon budget balance area, because the economic contribution coefficient of carbon emission and the ecological contribution coefficient of carbon sink are relatively high. Xiuwen County belongs to carbon sink functional area, which has a low carbon emission economic contribution coefficient, but a high carbon sink ecological contribution coefficient. Kaiyang County is a low-carbon optimization area, and the carbon emission economic contribution coefficient and the carbon sink ecological contribution coefficient are relatively low. Guiyang carbon balance zoning can provide scientific basis for Guiyang’s future economic and ecological development planning.
