| 英文摘要 | In recent years, high-molecular-weight anionic polyacrylamide (pam) have been widely tested on a variety of soils, primarily in water erosion control. however, little information is available regarding the effectiveness of pam on preventing soil loss from wind erosion. the research adopted room wind tunnel experiment, two kinds of soils were used which were from the agro-pastoral area of inner mongolia, the northwest of china, the clay content of soils were 22.0 and 13.7%, respectively. for these tests, all the treatments were performed under the condition of wind velocity of 14 m s(-1) and a blown angle of 8.75%, according to the actual situation of experimented area. the study results indicated that using pam on the soil surface could enhance the capability of avoiding the wind erosion, at the same time, the effect of controlling wind soil erosion with 4 g m(-2) pam was better than 2 g m(-2) pam's. economically, the 2 g m(-2) pam used in soil surface can control wind erosion effectively in this region. the prophase pam accumulated in soil could not improve the capability of avoiding the wind erosion, owing to the degradation of pam in the soil and the continual tillage year after year. the texture of soil is a main factor influencing the capability of soil avoiding wind erosion. soil with higher clay content has the higher capability of preventing soil from wind erosion than one with the opposite one under the together action of pam and water. |
