基于地面/遥感监测的严重沙化温性草原人工种草生态修复工程效益评价OA

On the basis of careful analysis of the status quo, problems and experience of grassland ecological protection and restoration in In-ner Mongolia, this study selected representative pilot areas to carry out pilot ecological restoration projects in the warm steppe of Inner Mongo-lia.Through the ecological benefit assessment of the ecological restoration project, it objectively reflected the achievements of the implementa-tion of the ecological restoration project in the warm steppe of Inner Mongolia Autonomous Region and the contribution to the local economic development.The results showed that after the implementation of ecological restoration measures for 3 years, the two restoration measures (fence+replanting+management, land leveling+replanting+fertilization+sand barrier) had obvious ecological benefits.The ecological restora-tion projects combining fencing, reseeding and management and protection had more obvious ecological benefits.The accuracy of remote sens-ing monitoring model fluctuated greatly, so it was still necessary to explore the technical means to improve the monitoring accuracy.
