1) soil venting
土壤通风
1.
The influence of air extracting velocity on the efficiency of soil venting was studied with column test using the field sand.
结果表明,真空抽提通风速率越大,土壤中的汽油烃去除速率越快,但通风速率由400mL·min-1提高到800mL·min-1,土壤污染物修复效果差异不太明显,最佳的土壤通风速率为400mL·min-1。
2) In-situ soil venting
土壤原位通风
3) Soil wind erosion
土壤风蚀
1.
Study of the effect on different distribution modes of Artemisia sphaerocephala to soil wind erosion is of great significance to ecological construction and preven- tion against soil wind erosion in the fixed and semi fixed sands.

2.
Wind tunnel experiments were conducted to Research the change process of soil wind erosion with the change of PAM controlling the soil wind erosion under the condition of the constant wind velocity of 14 s/m and the constant blown angle of 5°.
研究表明,对土壤表层覆盖PAM可以增加土壤的抗风蚀能力,有效地减少土壤风蚀,增加PAM使用量可以进一步增加土壤的抗风蚀能力,即4 g/m2PAM用量的效果要好于2 g/m2PAM的用量;前期累积在土壤中的PAM不能明显增加土壤抗风蚀的能力;在水分和PAM的共同作用下,黏粒含量高的土壤的抗风蚀能力要强于黏粒含量低的土壤。

A soil wind erosion experimental plot was set up in the alluvial sandy land of old yellow river,which is in Xiajin County of Shandong Province,and the soil wind erosion quantity was tested with measuring scale method in the observation farmland shelter-forest network and the comparison place.
在山东省夏津县黄河故道冲积沙地建立土壤风蚀试验区,采用标尺法对3种网格的农田防护林和对照地的土壤风蚀量进行观测,测定结果表明:农田防护林网可明显减少风蚀损失,其中,130m×300m林网相对于对照减少土壤风蚀量81%,260m×300m林网相对于对照减少78%,300m×400m林网相对于对照减少75%,即随着网格面积的增加对风蚀量的影响越来越小。
