| 摘 要： | 飞播治沙是一项快速而有效的治沙措施,是沙质荒漠化土地植被重建与恢复的重要途径。我国的飞播治沙无论是研究水平还是生产规模,都已走到世界的前列[1,2]。毛乌素沙地是我国飞播治沙试验开始最早、成效最为显著的沙区之一[1],然而,沙区飞播用种主要是能够适应流沙环境的物种[3],飞播后随着沙丘的固定及表层土壤的形成,沙层水分状况也随之变化。为此,探讨飞播后植被变化情况,研究飞播植被维持年限在生产实践中有其重要的意义。项目基金:国家林业局天保工程科技支撑项目“盐池县飞机播种造林绿化荒沙技术示范”;国家重点科技攻关西部专项课题…

| Abstract: | Based on 3-year's investigatin data of aerial seeding on Maerzhuang plot of Yanchi County,the changes of vegetation and dominant species population after aerial seeding were analyzed.The authors explored the relationship between vegetation change and habitat,and put forward some measures to prolong the growth phase of aerial-seeded plants.The results of the short-term investigation showed after aerial seeding,the species did not change a lot,but the vegetation coverage and biomass increased significantly. |

| Keywords: | aerial seeding vegetation change vegetation coverage biomass |
