摘要
沙棘是我国西北地区的重要经济作物,同时也具有较好的水土流失防治效果。以新疆伊宁市巴彦岱镇干沟村沙棘坡地为例,通过室外试验的方法,研究沙棘丛下降雨和产流、产沙的关系。结果显示,产流、产沙和降雨因子之间属于典型的幂函数关系,且沙棘丛林的年龄对产流、产沙特征不存在显著影响,新栽植的沙棘灌丛也可以获得良好的水土保持效果。
Seabuckthorn is an important economic crop in Northwest China,and also has a good effect of soil erosion control.Taking the Hippophae rhamnoides slope in Gangou village of bayandai town in Yining city of Xinjiang as an example,the relationship between rainfall and runoff and sediment yield under Hippophae rhamnoides cluster was studied by outdoor test.The results showed that there was a typical power function relationship between runoff,sediment yield and rainfall factors,and the age of seabuckthorn Bush had no significant effect on runoff and sediment yield characteristics,and the newly planted Seabuckthorn shrub could also achieve good soil and water conservation effect.
