针对退耕还林工程实施后农业资源存量较大及其未能有效地转化为生产力的现实，通过对陕北退耕区域典型流域碳汇量的测算、典型县域农业产业-资源系统互动关系的分析，探讨农用地碳汇产业特征及其作为退耕区域新的经济增长点的生态经济学基础；依据CDM之规定，将碳汇产业融入系统循环过程中，建立农业产业-资源系统的概念模型，选取可表征农业产业-资源耦合系统的变量或参数，使其概念模型数学化，形成农业产业-资源耦合过程模型。在此基础上，确定农业资源可开发利用的阈值及农业产业-资源系统可能发展的路径，研发适合于CDM需求的陕北退耕区域农业产业与农业资源系统耦合的可操作模式，构建系统耦合机制框图，提出耦合机制框图可实施的路径、保障措施及相应政策。为促进农业资源有效利用，实现CDM规制下的农业产业与农业资源相一致，加速农村产业升级和结构调整，稳固退耕还林工程成果方案的制定提供科学依据，为生态经济学和农业科学发展服务。

The research is mainly focused on the question that the agricultural resources cannot transform into productivity efficiently while it has potential storage after the implementation of Grain for Green Project. We measured the carbon sink of typical watershed in the returning farmland area, and analyzed the correlation between the agricultural industry and resources in typical county, they were very important for researching the ecological economics basis of agricultural land’s carbon sink industry characteristics and the new economic growth point of the returning farmland. Carbon sink industry had been integrated into the process of system cycle besed on CDM, the study established agricultural industry-resources conceptual model, selected variable or parameter which can characterize the agricultural industry-resources coupling mechanism to make its concept into mathematical model, and then formed the agricultural industry-resources coupling process model. On that basis, there was more to determine the thresholds of agricultural resources utilization and some possible future development paths of the agricultural industry-resources system, research and develop the operational mode of agricultural industry-resources coupled system to be suitable for the demans of the CDM in the returning farmland area of northern shaanxi, and built system coupling mechanism block diagram to propose the path, safeguard measures and corresponding policies which can be implemented. We do this to promote the effective use of agricultural resources, realize the consistence of industry-resources under CDM regulations, accelerate industrial upgrading and structural adjustment in rural areas, provide the scientific basis for stabilizing the grain for green project results, and serve the development of the ecological economics and the agricultural science.
