摘要: 区域碳收支核算是当前全球气候变化与碳排放研究的核心内容之一.开展县域空间碳收支与碳平衡研究不仅有助于从理论上构建县级尺度碳效率和碳生态压力评估的方法,而且对于县域空间碳补偿及低碳发展策略的制定也具有重要的现实意义.本文采用2009 年中原经济区县域单元的各种统计数据及土地利用数据,对县域空间的碳收支状况进行了核算分析,并在碳平衡分区的基础上提出了中原经济区主体功能区优化的思路和政策建议.主要结论:① 中原经济区2009 年碳吸收和碳排放总量分别为1.3 亿t 和2.1 亿t.碳排放量基本呈现“从市辖区到周边县(市) 逐渐降低”的规律;碳吸收量的分布具有“西北低、东南高”的特点;②县域空间碳补偿率的分布具有显著的区域差异,人均GDP 越高的地区,其碳补偿率往往越低;反之,碳补偿率越高;③ 由于县域单元碳源/汇具有较大的空间差异,中原经济区县域空间的碳排放经济贡献率和碳生态容量存在明显不匹配现象;④ 基于碳平衡分析,本文将中原经济区县域空间划分为碳强度控制区、碳收支平衡区、碳汇功能区、碳总量控制区及低碳优化区等5 类区域,并在此基础上提出了中原经济区主体功能区优化的思路及低碳发展策略.

Abstract: Regional carbon budget and carbon balance is one of the core fields of the studies on global climate change and carbon emission. Study on carbon budget and carbon balance based on county scale will not only help to establish theoretical framework for the evaluation of carbon efficiency and carbon ecological pressure on county- level, but also has great significance for county- level carbon compensation and the formation of low- carbon development strategies. Using statistical data and land use data of 2009 of each county in Central Plains Economic Region, the carbon budget and its spatial distribution of Central Plains Economic Region was estimated and analyzed, and furthermore the optimization scheme of main functional areas of Central Plains Economic Region based on carbon budget zoning was put forward. The main conclusions are as follows: (1) Total carbon absorption and carbon emission of Central Plains Economic Region in 2009 was 0.13 Gt and 0.21 Gt respectively. There appeared obvious spatial difference among each county. From the spatial level, carbon emission of each county gradually decreased from municipal district to circumjacent counties, while carbon absorption has a characteristic of lower carbon absorption in Northwest and higher carbon absorption in Southeast of Central Plains Economic Region. (2) There was remarkable spatial difference on carbon compensation rate. The higher the per capita GDP, the lower the compensation rate, and vice versa. (3) Economy contribution coefficient of carbon emission was obviously mismatched with carbon ecological capacity because of the different patterns in spatial distribution of carbon sources and sinks. (4) According to the result of carbon balance, the Central Plains Economic Region was divided into five kinds of areas based on the aim of regional low- carbon and harmonious development as follows: carbon emission intensity control area, total carbon emission control area, carbon sink area, carbon budget balance area and low-carbon optimization area. Finally, the optimization scheme for main functional areas of Central Plains Economic Region and the corresponding low- carbon development strategies was put forward based on the carbon balance zoning.
