| 摘要: |
| 青海湖流域土地沙漠化现象日趋严重，防治土地沙漠化的工作刻不容缓。本文通过野
外实验、室内分析，以粗糙度、风沙流结构、输沙率等为指标，评估了人工治沙措施在青海湖
流域沙区的防风固沙效益。采取人工治理措施设置麦草方格沙障，配合种植沙棘（Hippophae
rhamnoides）以或乌柳（Salix cheilophila）、沙棘间种，起到了明显的防风固沙效果。采取人工
治理措施的样地，近地表风速降低，粗糙度变大，输沙量减少，风沙流结构改变。 |

| Abstract: |
| It is imperative to prevent the detrimental phenomenon for increasingly desertification in
Qinghai Lake drainage area. In this paper, the benefi ts of vegetation measure on wind-breaking and sandfi
xation in Qinghai Lake drainage area are valued through fi eld testing and laboratory analysis. Planting
Hippophae rhamnoides only or planting both Salix cheilophila and Hippophae rhamnoides after setting
up the straw sand barrier could reduce wind speed and control sand move. The test sites with artifi cial
measures make the near-surface wind speed decreased, the roughness becomes larger, the sediment
discharge reduced and the wind-sand fl ow change. |
