| Abstract: | The ecological efficiency of Hippophae rhamnoides L., such as conserving water,preventing soil and water loss and protecting field was investigated and valued. The result shows:there are correct relation between conserving water function and product quantity; there is also correct relation between ecological efficiency and the layer height of falling stems and leaves. The ecological efficiency of Hippophae rhamnoides L is 2.11 times as econornical efficiency. |
