Pattern and Benefit of Ecological Restoration in Jiping Canal of the East Route of South-to-North Water Diversion Project

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.
