        Research and Demonstration on Increasing Carbon Sequestration Technology for North Fast-growing High-yield Forest and Orchard System
Abstract:
        Associated with other institutions, we have undertaken the national science and technology support program subject of research and demonstration on increasing carbon sequestration technology for north fast-growing high-yield forest and orchard system from the Ministry of Science and Technology, in order to promote sustainable management and development of carbon sequestration for the north poplar fast-growing high-yield forest and orchard complex ecosystem. The implementation period of the subject is from Jan.2009 to Dec.2011, and the total funding is 1.8 million RMB. The main contents of the subject are as follows: analysis and assessment on the distribution character of carbon pool and the capacity of carbon sequestration for the poplar fast-growing high-yield forest and orchard complex ecosystem on the north typical site conditions, and research on the technology of increasing carbon stock, and selection excellent poplar varieties, fruit species and composite plants which are suitable for large-scale development with high capacity of storing carbon, and integration corresponding management systems and population modes, and establishment of pilot and demonstration areas to promotion on large-scale. In 2010,we have mainly worked on the formation of the subject implementation team, and part of researches on the technologies of increasing carbon sink and the corresponding technology integration and demonstration establishment for the north poplar fast-growing high-yield forest and orchard complex ecosystem, which achieved initial results as to the expected year tasks.
        一、课题概述
        “北方速生丰产林与果园系统固碳增汇技术研究与示范”课题为我办联合北京林业大学和北京农学院共同申请的国家科学技术部国家科技支撑计划项目课题,实施期为2009.1-2011.12月,总经费为180万元。主要内容为:分析和评价北方典型立地条件下杨树速生丰产林与果园生态系统的碳贮库分布特征及其碳汇能力,研究杨树速生丰产林和果园复合系统固碳增汇技术,筛选适合大面积发展的高碳汇能力杨树品种、果树种类及其复合种植植物,集成相应的增汇管理技术体系和模式,并建立示范区进行大面积示范推广。
        二、2010年度工作简介
        1.北方速生丰产林固碳技术开发研究与示范
        开展了我国北方杨树速生丰产林碳储量研究,估算出6省市杨树速生丰产林的碳储量为73.83Tg(Tg=百万吨);进行了杨树速生丰产林固碳增汇优化水肥管理技术体系研究,初步形成增汇技术模式3套,即地下滴灌+随水施肥固碳增汇优化水肥管理技术模式;宽窄行配置+地下滴灌及随水施肥+林农(草)间作固碳增汇优化栽培技术模式;宽窄行配置+常规灌溉和施肥+林农(草)间作固碳增汇优化栽培技术模式。

        2.北方果园复合系统增汇模式研究与示范
        开展了北方果园复合系统果树及套种植物储碳能力比较研究,以及果园增汇技术措施与应用模式研究,筛选出较好的果园套种植物类型和增汇技术模式,即生态果园固碳增肥模式(三叶草-果树),生态果园固碳趋避模式(迷迭香—果树)和生态果园固碳增汇模式(花生或红薯—果树);采用涡度相关系统碳通量观测仪器对果园复合系统的增汇减排效应进行了评价,为北方果园系统增汇技术评价与示范提供了技术支撑。

        3.北方速生丰产林与果园系统固碳增汇技术集成与示范
        开展了杨树速生丰产林与果园复合系统增汇技术集成与示范区建设工作,分别在北京市通州区、顺义区和山东高唐县等地建立起杨树速生丰产林增汇技术示范区2千多亩,每公顷年固碳达9吨以上,土壤有机碳储量提高10%;在平谷区和昌平区等地建立起桃、枣、苹果等果园复合增汇技术示范区2千多亩,促进课题研究成果的示范推广及应用。
