Abstract:

This paper examined vegetation characteristics and soil physical and chemical properties under the three vegetation restoration measures in drifting sand land of northwest Sichuan to find the better restoration measures during ecological restoration. The results showed that after laying eco-mat,soil physical and chemical properties were improved significantly, and that the water conservation of soil was increased significantly. The vegetation coverage and plant diversity showed an increasing tendency. Therefore, shifting sandy land can be effectively controlled with eco-mat promoting ecological restoration and preventing sand removal.

Key words: Eco-mat, Northwest Sichuan, Shifting sandy land

摘要：

本研究以铺设生态毯、栽植植物、铺遮阳网3种治理措施的流动沙地为对象，以未采取措施的为对照，分析了不同治理措施下植被特征与土壤理化性质。结果表明：与对照相比，铺设生态毯后土壤平均含水率上升幅度最大；土壤容重和砂砾含量降低幅度最大；土壤有机质、全N、全P、全K含量上升幅度最大；地表植被盖度和物种多样性呈显著上升趋势。因此，铺设生态毯可促进流动沙地生态修复，防止流沙蔓延。
