摘　　要：恢复和重建荒漠化地区生态环境的重点工作是改善沙漠边缘的生态环境。对沙生植物沙米和黄篙进行喷灌、滴灌等田间试验,研究其生长指标。结果表明,在资源紧缺情况下,较大灌水定额不利于对沙米的生长,在黄篙出苗期、幼苗期灌水各50 mm,就能保证良好的生长状态。The key to restored and reconstruct the ecological environment in the desertification area lies in improving the ecological environment of the desert edge.A spray and drip irrigation experiment was conducted on Agriophyllum squarrosum（Linn.） Moq.and Artemisia scoparia to study their growth indices.The results showed that,in the context of resources shortage,large irrigation volume was not good for the growth of Agriophyllum squarrosum（Linn.） Moq.,while the guarantee of 50 mm irrigation respectively at the seedling stage and emergence stage of Artemisia scoparia would guarantee its well growth.
