It is very common that state-owned land and collective land coexist in natural protected areas,and it is also true for national park.This is a great challenge to balance the relationship between interests of community residents and natural conservation with high quality for national park.The easement system for natural protected areas abroad has been implemented for many years.Based on the experience summary and refinement for conservation easement operation in Qianjiangyuan National Park construction area,this study first presents technical systems for management and assessment about conservation easement.The management system includes:management process,program preparation,investigation and verification,publicity,formation of servitude land authorization documents,contract signing,and management system construction.The assessment system includes:assessment object,contentand type,process,data acquisition,assessment of contract performance,collective forest land and rural contracted land resource assets and ecological benefit assesment.The two systems provide practical rules for the realization of unified protection and management of natural resource assets in national parks dominated by collective land,which is typical and exemplary for the high-quality construction of a system of natural protected areas with national parks as the main body and the promotion of innovation in the management system.
