中文摘要	在宁夏盐池风沙区选取油蒿(Artemisia ordosica)、花棒(Hedysarum scoparium)、沙拐枣(Calligonum mongolicum) 、柠条(Caragana korshinskii)4种草方格人工固沙灌丛林地为研究样地,以周围流动沙地为对照,研究了4种固沙模式下土壤理化性质变化特征,采用土壤质量综合指数探讨了不同人工灌丛固沙措施对土壤质量的影响。结果表明:(1)与流动沙地相比,土壤粗砂含量表现为油蒿林地显著提高,花棒、柠条和沙拐枣林地无显著变化。土壤细砂含量表现为沙拐枣林地显著提高,而油蒿、柠条和花棒林地无显著变化。土壤极细砂含量表现为沙拐枣林地显著降低,而油蒿、柠条和花棒林地无显著变化。土壤黏粉粒含量表现为油蒿林地显著增大,而花棒和沙拐枣林地显著减小,柠条林地则无显著变化。(2)从流动沙地到固沙林地,土壤容重表现为沙拐枣林地显著增大,而油蒿林地显著减小,花棒和柠条林地则无显著变化。土壤pH表现为沙拐枣林地显著增大,而油蒿、花棒和柠条林地无显著变化。土壤含水量、电导率、有机碳、全氮和碳氮比均表现为油蒿林地显著提高,而花棒、沙拐枣和柠条林地间以上5项指标均无显著变化。(3)土壤质量综合指数表现为油蒿林地(3.15)>流动沙地(-0.03)>柠条林地(-0.56)>花棒林地(-1.05)>沙拐枣林地(-1.54)。研究表明,流动沙地扎设草方格营造油蒿林能在短期内提高风沙土壤综合质量,而其他造林方式固沙效果有限。
英文摘要	In the desertified area of Yanchi,Ningxia,we selected four types of sand-binding shrub plantations within straw checkerboard of A.ordosica,H.scoparium,C.mongolicum and C.korshinskii as study sites, with the adjacent mobile sand land as control sites.An investigation on the changes of soil physical and chemical properties,and the soil comprehensive quality index was carried out in the revegetated sites under four types of sand-binding modes.The present study was to probe into the effect of sand-binding plantations within straw checkboard in terms of shrub species on soil quality during the revegetation process.The results showed that:(1)it was found that the soil coarse sand content increased significantly in the sites after revegetation by A.ordosica,whereas there were no significant differences between the soils in H.scoparium,C. korshinskii,C.mongolicum plantations and mobile sand land;the soil fine sand content increased significantly in the sites after revegetation by C.mongolicum,whereas there were no significant differences between the soils in A.ordosica,C.korshinskii,H.scoparium plantations and mobile sand land;the soil very fine sand content decreased significantly in the sites after revegetation by C.mongolicum,whereas there were no significant differences between the soils in A.ordosica,C.korshinskii and H.scoparium plantations and mobile sand land;compared with the mobile sand land,the soil clay and silt contents increased significantly in the sites revegetated by A.ordosica,and decreased significantly in the sites revegetated by H.scoparium and C. mongolicum,whereas there were no significant differences between the soils in C.korshinskii plantations and mobiles and land;(2)the soil bulk density increased significantly in the sites after revegetation by C.mongolicum, and decreased significantly in the sites after revegetation by A.ordosica,whereas there were no significant differences between the soils in H.scoparium,C.korshinskii plantations,and the mobile sand land;soil pH increased significantly in the sites after revegetation by C.mongolicum,whereas there were no significant differences between the soils in A.ordosica,H.scoparium,C.korshinskii plantations and the mobile sand land;the soil water content,electrical conductivity,organic carbon,total nitrogen and ratio of carbon to nitrogen increased significantly in the sites after revegetation by A.ordosica,whereas there were no significant differences between the soils in H.scoparium,C.mongolicum,C.korshinskii plantations and the mobile sand land;(3)the soil quality comprehensive index followed the order:A.ordosica (3.15)>mobile sand land (-0.03)>C.korshinskii (-0.56)>H.scoparium (-1.05)>C.mongolicum (-1.54),suggesting that soil quality was improved in the sites after revegetation by A.ordosica.It was concluded that the construction of A.ordosica plantations within straw checkerboard could improve desertified soil quality in a short time, whereas there were limited effects of other three types of sand-binding shrub plantations within straw checkerboard in the desertified area of Yanchi,Ningxia.
