介绍了森林景观恢复潜力评估方法(ROAM),以及运用其在河北省丰宁满族自治县(试点景观)开展评估的过程和评估结果。评估发现,丰宁满族自治县实施2021—2030年的森林景观恢复综合措施,有潜力以7.5亿的年投资撬动每年21.6亿的经济和生态效益,全项目期投入产出比为1∶1.23。ROAM能够综合分析不同景观要素,包括自然生态系统基础、景观退化的生态系统和社会经济根源、当地社区的经济发展需求和环境生态产品供给收益等,从而使编制的生态修复规划更具有科学性和可行性。研究显示,ROAM在山水林田湖草综合规划和国家重大生态系统修复项目中具有较大的应用潜力。

This article introduced the Restoration Opportunities Assessment Methodology(ROAM),and the process and results of applying it to assess a pilot landscape(Fengning Manchu Autonomous County,Hebei Province).The assessment showed that with the implementation of comprehensive forest landscape restoration measures by Fengning County,a FLR investment of 750 million Yuan could deliver an annual economic and ecological benefit of 2.16 billion Yuan,that would be an input-output ratio of 1∶1.23 over a ten-year period.The assessment covers such elements as biophysical conditions,socio-economic causes of landscape degradation,development needs of local communities and economic and environment benefits from restoration products,so as to develop a feasible and effective restoration interventions.This study showed that ROAM has great application potential in the planning of mountain-river-forest-farmland-lake-grassland integrated restoration,and other major national ecosystem restoration projects.
