【目的】建立林业生态工程多目标效益评估框架,评估京冀合作造林工程的综合效益,以期推动区域生态、经济与社会的协同发展。【方法】基于利益相关者理论,采用Mitchell评分法界定京冀合作造林工程涉及的利益相关者。根据目前京冀合作造林工程建设的推动者、工程执行者及受益者等因素,重点研究京冀合作造林工程中的核心利益相关者,即作为政策设计者和推动者的北京市政府、作为政策执行者的河北省市县级地方政府以及作为政策最终作用对象的工程覆盖区农户3方利益主体。在此基础上,对3方利益群体在京冀合作造林工程的价值取向和目标进行分析,指出基于多目标的造林工程是各利益群体缔结的多元共生体,应追求经济、社会和生态效益的协同发展,并从评估主体、评估目标及评估阶段3个视角阐述京冀合作造林工程综合效益评估框架。【结果】在京冀合作造林工程效益评估框架的基础上,将造林工程效益评估的时间、空间及目标3个维度相结合,任意3个维度的组合构成京冀合作造林工程的一个效益评估模块,共计27个模块即效益立方体模型;并根据各效益评估模块的重要程度,将27个效益模块分成关键模块、重要模块及一般模块。【结论】将评估主体、评价目标和评估阶段3个方面有机结合起来构建的京冀合作造林工程效益立方体模型能够从不同角度综合反映特定的对象、内容及环节的效益水平,使林业生态工程综合效益评估更具科学性、系统性和决策相关性。京冀合作造林工程建设必须基于"三重底线",即经济财富、社会福祉与生态平衡的协同发展。针对京冀合作造林后续工程建设,从造林目标的制定、流域合作机制及参与式林业政策过程提出优化建议,最终实现京冀合作造林工程生态、社会与经济效益的三赢目标。
【Objective 】 The objective of establish the benefits evaluation framework of multiple targets of forestry ecological engineering to evaluate the comprehensive benefit of the cooperative afforestation engineering between Beijing and Hebei province is promoting the coordinated development of regional ecology,economy and society. 【Method 】The paper adopts Mitchell scoring to define stakeholders cooperative afforestation engineering between Beijing and Hebei province based on stakeholder theory,then focus on the core stakeholders: Beijing government,the local governments in Hebei Province and farmers of project coverage area. On the basis of above,this paper analyses the value orientation and goal of the above-mentioned three stakeholders. As a symbiosis body composed by stakeholders,afforestation engineering should pursue harmonious development of economy ecology and society. The paper builds a framework of multiple targets offorestry ecological engineering from three perspective: principal part,object and phase.【Result】Based on the above,the paper integrates a benefit cube from three dimensions: the time,space and object,any of three dimensions can form a benefit module,the number is add up to 27,and these modules are divided into three levels: the key modules,important modules and general modules.【Conclusion】The benefit cube integrated by principal part,object and phase can reflect the benefit levels of specific objects,contents and process. Making the benefit appraisal of forestry ecological engineering more scientific,systematic and decision-making relevance. The cooperative afforestation engineering between Beijing and Hebei province must be based on "triple bottom line",which are the harmonious development of economic wealth,social wellbeing and ecological balance. The paper optimizes for the subsequent construction of the cooperative afforestation engineering between Beijing and Hebei province from the target setting,cooperation mechanisms and participatory forest policy process,th
