在认真分析内蒙古草原生态保护修复现状、问题及经验的基础上,在内蒙古温性草原选择了有代表性的试点区域开展生态修复工程试点工作,并通过对不同生态修复措施进行生态效益评估,客观反映内蒙古自治区温性草原实施生态修复项目后取得的成果和对当地经济发展作出的贡献.结果表明:温性草原严重沙化草地在生态修复措施实施3年后,2种修复措施(围栏+补播+管护、土地平整+补播+施肥+沙障)均具有明显的生态效益;采取围栏、补播、管护相结合的生态修复工程,其生态效益更为明显;遥感监测模型精度波动较大,仍需探索提高监测精度的技术手段.
Evaluation on the Benefit of Ecological Restoration Project of Artificial Grass Planting in Severe Desertified Warm Steppe Based on Ground Monitoring/Remote Sensing Monitoring
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.
