5) runoff
[英]['rʌn,ɔ:f] [美]['rʌn,ɔf]
径流损失
1.
Through the study of plot runoff resource,3 herb vegetation types,3 shrub vegetation types and 3 arbor vegetation types in loess hilly region,.
通过对3种草本、3种灌木、3种乔木植被类型的小区径流资料分析研究,结果表明就减少径流损失作用而言,灌木作用最为明显,草本次之,乔木最差;就减少土壤侵蚀作用而言,灌木作用最为明显,乔木次之,草本最差;草本、灌木、乔木植被类型的年土壤侵蚀量和3种植被类型中的草本盖度表现出相反的趋势,即草本盖度越高的草本、灌木或乔木植被类型,年土壤侵蚀量越低。
