摘要
针对在陕北黄土丘陵沟壑区实施的植被恢复及不同土地利用类型调整的政策,在小区和流域尺度上,就植被恢复对流域水土流失、养分流失、养分循环平衡影响方面的国内外研究概况进行了综述。指出植被恢复可减少流域水土流失和养分流失,使流域养分循环平衡能力加强、向良性循环方向发展,同时指出了在这方面需进一步研究的问题。
According to the policy of vegetation restoration and different land use type adjustment in loess hilly region, vegetation restoration affecting the soil erosion, nutrient discharge and nutrient cycling and balance of watershed are reviewed on field plot and watershed. It is pointed out that vegetation restoration can reduce soil erosion and nutrient discharge, strengthen the ability of watershed nutrient cycling and balance, make the watershed nutrient cycling and balance develop to a health way on the watershed. Several issues should be deeply researched in the this area.
