| 摘 要： | 对岷江上游杂谷脑河流域干旱河谷区典型地段植被及其生物多样性进行了研究。结果表明：岷江上游杂谷脑河流域干旱河谷区植物种类较少，且具有荒漠化半荒漠化性质，阴坡植被明显比阳坡丰富；该区植被及其生物多样性指数在阴坡和阳坡均表现出随海拔升高而增大的趋势；该区域植被恢复宜从阴坡着手。 |

| Abstract: | The vegetation and its biodiversity of a typical arid area were studied in Zagulao river valley at the upper reaches of Minjiang River. Results showed that the plant species were less and had the characteristic of desertification and semi - desertification. The vegetation on shade slopes was obviously richer than that on south - facing slopes. The vegetation and the biodiversity index of shade slops and south - facing slopes all showed the tendency of increasing with elevation. Therefore, the recovery of vegetation in this area ought to begin with the shade slope. |
