砾石

Glaciers and their immediate environs present many dangers for humans, such as crevasses and glacier mills into which one might fall, heavily crevassed ice falls, snow and ice avalanches from the side walls and, along the flanks, dumping of great boulders, ponding and floods from melt water.

冰川及其周边事物给人们带来众多威胁，比如冰隙（冰川插进来可能会造成崩塌）、冰瀑的严重裂缝、沿着边缘的侧墙发生的雪崩或冰崩、大块砾石的滚落、积水以及融水的泛滥。

The results showed that the soil water contents of sand, A. ordosica and C. korshinskii vegetation in lysimeters all increase due to bitumen felt cover, especially of the CK. The canopy, new branch length and leaf area index also grow in experimental period. But the CK consumes a little water because the neutron probecan t detect the water in gravel layer.

结果表明蒸渗池表面自油毡覆盖至试验结束，油蒿、柠条和流沙处理0～150cm土层土壤含水量都增加，尤其流沙处理土壤含水量上升最明显；油蒿与柠条的冠幅、新梢长和叶面积指数均增加；由于中子仪探测不到蒸渗池底部40cm厚的砾石层的水分，导致了对照流沙处理测定结果不合常规。
