- 摘要:
- 利用水分扩散装置对丹江库区典型坡面4个土地利用3个土层的硝态氮水平运移规律进行了研究。结果表明：硝态氮水平运移速率随距离增加而迅速减小，呈幂函数曲线降低。由于人为扰动及水土流失作用各土层性质不同，硝态氮运移曲线发生分异，河漫滩和柑橘园地在距离20 cm后趋于平稳，而消落区撂荒地和库滨带坡耕地在35 cm后才趋于平稳；消落区撂荒地和库滨带坡耕地土壤硝态氮运移速率随着土壤深度增加逐渐减小，而河漫滩和柑橘园地表现为相反趋势。硝态氮浓度最大值均出现在湿润锋（土壤干湿交界面）上；硝态氮水平运移浓度随土壤含水量的增加而减小，变化趋势符合幂函数关系。
- Abstract:
- The horizontal transport of nitrate in soils from different land use along an altitudinal transect in Danjiangkou Reservoir was studied. The results were as follows. The horizontal transport velocity of nitrate decreased with increase of transport distance as power function. Due to soil properties from different land use, the curves of horizontal transport of nitrate were different; the horizontal transport velocity of nitrate from floodplain and citrus orchard was stable beyond 20 cm, and was stable beyond 35 cm for abandoned land in hydro-fluctuation belt and slope land in riparian buffer strips; the horizontal transport velocity of nitrate for abandoned land in hydro-fluctuation belt and slope land in riparian buffer strips decreased gradually with soil depth, and the opposite trend was observed for floodplain and citrus orchard. Transport concentration of nitrate reached to maximum value at the surface of wetting front which occurred on the interface between wet and dry soil; nitrate transport concentration decreased with increase of the soil moisture content and their relation could be fitted by power curve.
