摘要:
在青海大通县北川河流域分浅山区和脑山区各选择了5种退耕还林配置模式，研究了不同配置模式对土壤抗冲性的影响，结果表明：在浅山区，土壤抗冲性指数与枯落物现存量呈显著正相关，以模式D（中国沙棘）的抗冲性指数最大，为1.136 s/g，以模式E（柠条）的最小，为0.385 s/g；在脑山区，土壤抗冲性指数与团聚度、总孔隙度呈显著正相关，模式F（青海云杉）的土壤抗性指数最大，为1.652 s/g，模式J（青杨+中国沙棘）的土壤抗冲性指数最小。
Abstract:
The study on the influence of different species arrangement models on anti-scourability of soil was carried out in Beichuanhe watershed, datong county, Qinghai, through five models of Converting Cropland to Forest selected in low mountain areas and high mountain areas respectively.The main conclusions are as following:in low mountain areas, the index of soil anti-scourability is in evidently direct proportion to the existent masses of litter layer.The index of soil anti-scourability of model D (Hippophae rhamnoides ssp.sinensis) ranks first, up to 1.136 s/g, model E (Caragana korshinskii)is less than others, up to 0.385s/g, in different species arrangement models.In high mountain areas, the index of soil anti-scourability is in evidently direct proportion to the degree of aggregation and the total pore space.The index of soil anti-scourability of model F (Picea crassifolia) ranks first, up to 1.652 s/g, model J (Populus cathayana+Hippophae rhamnoides ssp.sinensis)is less than others in different species arrangement models.
