中文摘要	在黄河首曲沙化草地流动沙丘迎风坡建立流沙治理恢复试验区,共设3个区组6个处理(羊粪、羊粪+保护种、羊粪+纤维网方格沙障+保护种、羊粪+泥炭土、羊粪+泥炭土+保护种和对照,以下简称粪、粪+保、粪+网+保、粪+土、粪+土+保和对照)同一混播草种的随机区组试验。观测混播草种的出苗密度、生长高度、投影盖度和不同处理的风沙侵蚀堆积程度。结果表明:1) 6个处理中,粪+网+保和粪+土+保的处理沙面相对稳定,混播草种能够成功定居萌芽和出苗生长,而其他4个处理沙面风蚀严重,仅在粪+土和粪+保两个处理沙面有稀疏出苗;除投影盖度外,粪+网+保和粪+土+保的平均高度、密度间均无显著差异(P > 0.05),但均显著大于其他4个处理(P < 0.05);2) 粪+网+保和粪+土+保的风蚀深度间差异不显著(P > 0.05),除粪+土外,均显著小于其他各处理(P < 0.05)。另外,各处理风积厚度间无显著差异(P > 0.05)。研究表明, 粪+网+保和粪+土+保处理均具固沙和促进草地恢复的双重效果,可以作为解决当地沙丘治理并恢复草地的创新综合配套技术模式。
英文摘要	We established an experimental area on the windward slope of mobile dunes in the first bending of the Yellow River, as part of a pilot project to test sand controlling and grassland restoration techniques. The experiment was designed as 3 randomized block groups, exposed to 6 different treatments as follows: Dung (sheep dung), Dung+ protect (sheep dung+ protective species), Dung+ mat+ protect (sheep dung+ fiber grid sand barrier+ protective species), Dung+ soil (sheep dung+ peat soil), Dung+ soil+ protect (sheep dung+ peat soil+ protective species), and CK (control). The same formula of grass seeds was used in all treatments, and the germination and seedling density, growth height, projection coverage of grass, and the degree of wind-sand erosion accumulation were observed. The results showed the following: 1) In the six treatments, the treated sand surfaces were relatively stable, and grass seeds successfully settled, germinated. Seedlings grew in both Dung+ mat+ protect and Dung+ soil+ protect treatments. Wind severely eroded the sand surfaces and the seeds were consequently not planted for the other four treatments. There were no significant differences in average heights and the densities of grass except for projection coverage (P > 0.05). The averages of all other indicators in Dung+ mat+ protect and Dung+ soil+ protect were significantly higher than those of the other four treatments (P < 0.05). 2) The mean values of wind erosion were small for Dung+ mat+ protect and Dung+ soil+ protect, and there were no significant differences between them (P > 0.05). These values was significantly lower than those for the other treatments, except for Dung+ soil (P < 0.05). In addition, there were no significant differences in the mean values of aeolian production for all treatments (P > 0.05). These findings suggested that Dung+ mat+ protect and Dung+ soil+ protect performed well in sand-fixing and promoting grassland restoration. These findings can be implemented as novel complex technologies to successfully address the sand-fixing concerns and improve grassland restoration in this area.
