| 摘 要： | 为了定量评价净风吹蚀下植被覆盖地表的抗风蚀性能,利用移动式风蚀风洞对试验区地表进行原位测试.结果表明:不同风速下土壤风蚀量随植被盖度的增加呈指数规律减少,土壤防风蚀的植被盖度在30%以上较为显著;当风速为10m/s以上时,试验区的有效防风蚀植被盖度须达到40%以上,当风速为14～18m/s时,其有效植被盖度须达到60%～80%的水平. |
| 关 键 词： | 植被盖度 测试 风蚀量 有效植被盖度 |

| Abstract: | The test was carried out on the nature surface by means of the movable wind tunnel in order to evaluate quantificationally the anti-erosion properties of vegetation coverage land surface blown by wind.The result shows that the amount of soil wind erosion decreases exponentially with vegetation coverage increasing in the case of different wind velocity.The amount of anti-wind erosion is conspicuous as its vegetation coverage is above 30%.The measured area's effective anti-erosion vegetation coverage is deter... |
| Keywords: | vegetation coverage measure the amount of soil wind erosion effective vegetation coverage |
