摘　　要：为研究牛羊粪对高寒区沙化土壤和植被生长的影响,探索高寒区沙化土壤的治理新技术,本文在流动沙丘上设置2 cm牛羊粪覆盖+无沙障、1 cm牛羊粪覆盖+沙障、无牛羊粪覆盖+沙障、无牛羊粪覆盖+无沙障4种种草模式作为研究对象,分析不同处理对植被生长和土壤的影响。结果表明,(1)牛羊粪的使用增加了沙土粘粒和粉粒的比重,土壤结构变得更加稳定,抗侵蚀能力增强,为植被生长提供了一个稳定的土壤环境。(2)牛羊粪的使用增加了土壤养分,植被的生长与土壤养分呈极显著正相关关系,证明牛羊粪的使用对高寒区植被的生长起到助力作用。(3)纤维网有一定的防沙作用,但对土壤的养分和结构没有显著的影响。(4)当牛羊粪覆盖到一定厚度时,起到了沙障的作用,在高寒区沙化土壤修复中覆盖牛羊粪时,可以减少其他沙障的使用。In order to reserach the infiuence of the cattle manure and the sheep manure on vegetation growth in the desertified land and soil characteritics in alpine region,to explore new technique in order to govern the desertified land,this paper analyse the influence under 4 difference parttens which is 2 cm high manures covered+no sand barrier;1 cm high manures covered+sand barrier;no manure+sand barrier and no manure+no sand barrier in mobile sand dune.The results showed as below,(1)the manures using enhance the proportion of clay particle that makes the soil structure becoms more stable and anti-erosion,its provides a stable soil environment for vegetation growth.(2)The manures improving the soil nutrients,there was a significant positive correlation between vegetation growth and soil nutrients,that means the manures using having the dynamic effects on vegetation growth in alpine region.(3)Even though the sand prevention net has effects on sand prevention,its has no significant influence on soil nutrients and soil structure.(4)When the manure is covered to a certain thickness,the mamure acts as a sand-protecting barrier. Using manure to resotre the desertified land in alpine region could reduce other sand barries’s using.
