Abstract:

Using data from forestry and other sectors,the first-level zone based on physical geographical condition and the second-level zone in Yihe River Basin were determined.The second-level zoning mainly takes eco-service functions into account.74 forest landscape restoration areas were zoned with township boundary.Nine techniques of forest landscape restoration were designed,so as to evaluate the value of ecological services before and after the FLR action in Yihe River Basin.The evaluation showed that primary forest improvement,active management and agroforestry were key points of FLR in Yihe River Basin.After the restoration,total value of eco-services of the forest landscapes was 40.62 billion Yuan,which was 1.33 times of the value prior to the restoration intervention.In summary,experience from the Yihe case is the zoning of landscape restoration area based on natural geography and eco-service functions at watershed scale,together with township boundary,and the development and implementation of FLR technology.The experience provides some guidance on future FLR in Yihe River Basin and other landscapes as well.

Key words: Yihe River basin, forest landscape restoration, technology, application, evaluation
