Physical process of the effect of Locust artificial forest on the rainfall and the rules of water and soil losses under storm condition were analysed quantitatively and qualitatively. Raindrop kinetic energy per unit rainfall volume both of storm in the open field and canopy were calculated; distribution parameters of raindrop size were measured; models of rainfall amount in the form of stemflow and the interceptionby crown were established; EbI10-the complex index of rainfall erosi-vity were given.

本文定量及定性地分析了刺槐人工林影响降雨的物理过程以及暴雨条件下的水土流失规律。计算了空旷地及林冠下单位降水水体的雨滴动能;测定了林冠下降雨雨谱分布参数;确定了林冠截持雨量及干流量的数学模型以及刺槐林地降雨侵蚀力的复合指标-E_bI_(10)

Through studying the improving effect of seabuckthorn and black locust artificial forests in loess plateau to soil fertility with soil profile fertility analysis method. The results indicated that: ① The soil fertility can be enhanced greatly by the seabuckthorn and black locust artificial forests of the loess plateau. The soil organic matter, total nitrogen,available nitrogen, available potassium, CEC (cation exchange capacity) of 0~80cm soil horizon increased 41 1%,60 4%,109 7%,5 8%,12 4%...
