Pattern and Benefit of Ecological Restoration in Jiping Canal of the East Route of South-to-North Water Diversion Project
摘要
Abstract
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 be divided 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 50.9%.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.关键词
