沙柳坡位对沙柳生长状况的影响研究

Study on the Influence of Salix Slope Position on the Growth of Salix

沙柳广泛分布于沙漠及沙地,是一种能够有效改善生态环境的生物资源。通过对库布齐沙漠流动沙丘迎风坡不同坡位处沙柳各生长指标进行调查分析,结果表明:迎风坡底部利于沙柳植株存活,保存率较高;不同坡位对沙柳各生长指标影响不同,迎风坡中部利于沙柳进行高生长,迎风坡底部沙柳粗生长较好,迎风坡上部枝条分枝及生长较好;综合看来,迎风坡底部环境条件更适于沙柳的生长。

Salix is widely distributed in desert and sandy land. It is a kind of biological resource that can effectively improve the ecological environment. The results show that the bottom of the windward slope is beneficial to the survival of Salix and the preservation rate is high, and the influence of different slope positions on the growth index of Salix is different, the middle of the windward slope is beneficial to the Salix, and the sandy willow at the bottom of the windward slope is coarse. The branches of the windward slope are better and the growth conditions are better. According to the comprehensive view, the environmental conditions at the bottom of the windward slope are more suitable for the growth of Salix.
