Abstract:
 In order to explore the ecological service value of forest resources in the loess hilly and gully areas of Longdong (Eastern Gansu),to provide a popular and replicable paradigm for ecological restoration,protection and forest ecological service evaluation in this region.Based on the second-class forest resource survey data of Jingchuan County in 2018 and related literature data,and in accordance with the "Forest Ecosystem Service Function Evaluation Specification" of China,10 indicators from 4 aspects were selected to construct an evaluation system.Methods such as market value method and price substitution method were adopted to conduct the evaluation.The results showed that the total service value of the forest ecosystem in Jingchuan County in 2019 was 283.600 0 million yuan.The service value of water conservation was the largest,accounting for 50.76% of the total; the cultural tourism service value was the smallest,accounting for 0.002 5% of the total; ecological forests were mainly based on the value of water conservation services,non-timber forest was dominated by the value of supply services,and the annual service function of ecological forests.The ecological value was 3.8 times of the non-timber forest.The three values of water conservation,carbon fixation and oxygen release,and product supply accounted for 80.21% of the total service value,which were the main values for ecological service functions.The key tasks of forest resource management in the region were suggested:to build and cultivate mixed forests according to local conditions,strengthen the restoration and reconstruction of existing forest stands,improve the quality of forest resources,and innovate the management strategies.
