退耕区域发展碳汇产业的生态经济学思考

碳汇产业,即利用植物吸收二氧化碳的潜力及规律,在人工适度干预下获得清洁空气、满足人们生产和生活对生态环境需求的产业,为原有相对均衡或稳定的农业产业-资源系统的优化升级提供突破口和新的增长点.退耕区域生态系统服务中,固碳释氧功能的经济显化、碳汇潜力的迅速提高,以及国内外碳汇交易与碳汇市场的兴起等,为碳汇产业的发展奠定了理论和现实基础.随着碳汇产业的发展,生产经营者必然以提高碳汇产出为核心,形成对碳源的控制及对碳贮量增加路径的开发,重新布局农业产业-资源结构,因而为退耕区域可持续发展带来新的活力;同时,也隐含了下一步需要研发的重点,即碳汇产业融入后的农业产业-资源的配置结构及良性耦合机制.

Eco-economic thinking for developing carbon sink industry in the de-farming regions

Based on the potential and the law that plants absorb carbon dioxide, carbon sink industry means certain appropriate artificial intervention to obtain clean air, and to meet people’s production and life demand for ecological environment industry. Carbon sink industry is considered as a breakthrough point and a new growth point for optimizing and upgrading of the original relatively balanced or stable agricultural industry-resources system. Among the ecosystem services in the de-farming regions, the rapid increase of the economic manifestation of carbon fixation and oxygen release function and the carbon sink potential, as well as the rise of carbon trading and carbon market both in domestic and international, have established a theoretical and practical basis for the deve-lopment of carbon industry. With the development of the carbon sink industry, improving the carbon sequestration output will become the core of the carbon sink industry. The producers or marketers will form the controlling of the carbon source, the development of the path for carbon storage increasing and re-layout of agricultural industry-resources structure, and thus bring new vitality to regional sustainable development in the de-farming regions. This indicates the emphasis for the future research and development, that is, allocating the agricultural industry-resources structure and their benign coupling mechanism after integrating the carbon sink industry.
