用法例句

These complex geology stratum areas cause serious problems of soil erosion, landslide, traffic safety and landscape destroyed.

台湾第二高速公路南部路段之地理位置为横跨台南、高雄、屏东三县,沿线通过地质复杂的泥岩、砂岩及砾石层等地质区,经常导致土壤冲蚀、边坡崩塌且有危及行车安全与公路景观。

In order to accelerate national land reconstruction,vegetation engineering of soil and water conservation often put adhesive into the project of sprayed work to make plant seed effective staying and growing,and there is the purpose of protecting slope land surface for soil erosion.

为了加速国土的复育,水土保持植生工程中常加入黏着剂除使植物种子有效的停留于坡面生长外,也有保护坡面防止土壤冲蚀的目的。

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。
