碳收支和碳补偿分区的研究,对于制定适应各区域低碳发展策略,推动区域生态环境协同治理,实现可持续发展具有重要意义。本文以松花江流域28个城市及自治州为研究区,通过测算该流域内城市的碳收支及碳补偿金额并结合生态承载力系数和经济贡献系数,研究松花江流域城市碳收支的时空分异规律以及碳补偿分区,研究显示:(1) 松花江流域城市碳吸收情况以21 × 107 t位为平衡点上下浮动,在20年间呈现总量减少,减量较小,整体稳定的特点;碳排放呈现阶段式增长的趋势,分为2000~2010年快速增长阶段,和2010~2020年平稳增长阶段。(2) 2000年~2020年松花江流域各城市碳收支地域分异明显。碳排放主要集中于东北部地区,碳吸收主要集中于西北部和哈尔滨市。(3) 根据碳补偿量化分析,本文将研究区划分为5类碳补偿空间优化区,并为不同类型区的绿色低碳发展规划提出建议。The study of carbon budget and carbon compensation zoning is of great significance for specifying low-carbon development strategies to adapt to various regions, promoting regional ecological and environmental collaborative governance, and realizing sustainable development. This paper takes 28 cities and autonomous prefectures in the Songhua River Basin as the research area. By calculating the carbon budget and carbon compensation amount of cities in the basin and combining the ecological carrying capacity coefficient and economic contribution coefficient, the paper studies the spatial-temporal differentiation of the carbon budget of cities in the Songhua River basin and the carbon compensation zoning. The research shows: (1) The carbon uptake of cities in the Songhua River basin fluctuated up and down at the equilibrium point of 21 × 107 t, showing the characteristics of total decrease, small reduction and overall stability in the past 20 years;Carbon emissions showed a stage-like growth trend, which was divided into a rapid growt
