摘要 在全面总结南水北调东线济平干渠工程生态修复模式的基础上,结合水土保持监测成果,对济平干渠工程生态修复效益进行了分析研究。结果表明:济平干渠生态修复可以分为防护林模式、植物护坡模式、管理区及防护林苗木基地模式3种配置模式。工程扰动土地整治率达到99.7%,水土流失总治理度达到99.6%,工程拦渣率达到100%,土壤流失控制比为2.10,林草植被恢复系数为99.4%,林草植被覆盖率达到50.9%。工程水土流失影响指数(SWII)为0.0873,生态修复取得了良好的蓄水保土效益、生态效益和社会效益。 Based on the ecological restoration practice and the soil and water conservation monitoring of the Jiping Canal of the East Route of South-to-North Water Diversion Project, the ecological restoration pattern and benefit was examined in this study. The results indicated that the ecological restoration patterns of Jiping Canal could bedivided into three models: protection forest model, vegetable slope protection model and tree nursery base model. The treatment percentage of disturbed land was 99.7 % ; the controlled percentage of erosion area was 99, 6% ; the percentage of dammed slag or ashes was 100%;the controlled ratio of soil erosion modulus was 2. 10;the recovery percentage of the forestry and grass was 99. 4% and the percentage of the forestry and grass coverage was 50. 90%. The soil erosion and water loss influence index (SWII) of the project was 0. 0873. It suggests that the project have good soil and water conservation benefit,ecological benefit and social benefit.
