| 摘 要： | 坡地水土流失对三峡库区生态环境与可持续性发展构成双重压力.生物篱技术是一条有效防治水土流失、提高土地生产潜力的坡地改良利用途径.本研究以饲草玉米为纽带营建坡地生物篱模式,经4 a定位试验探讨了其生长状况和水土保持效益.结果表明,饲草玉米生物篱能有效改善陡坡地土壤性状、固持土壤、截持径流、减少养分流失,对减少库区水土流失与面源污染,保持和提高坡地生产力具有重要作用. |

| Abstract: | Slope-land plays an important role in the agricultural economy in th Three Gorges Reservoir Area, and its soil and water loss brings a double pressure on both eco-environment of the reservoir area and the sustainable development of agriculture.Preventing soil erosion and improving productivity of slope-land is the main target of the plant hedgerow technology.On the basis of contour tillage and agro-forestry, this paper choosed the forage maize(SAUMZ1)as the hedgerow plant and carried out a long-term observa... |
