中文摘要	以古尔班通古特沙漠引水工程沿线草方格沙障设置区域为研究对象,分析了不同铺设年限草方格沙障对表层土壤有机质、速效氮、速效磷和速效钾的影响。结果表明,铺设草方格沙障可提高土壤有机质、速效氮、速效钾的含量,其中速效氮和速效钾含量增加趋势最显著(P<0.05),但对速效磷含量影响不显著(P>0.05)。土壤养分含量随草方格沙障铺设时间延长而逐渐增加,但达到一定阶段后趋于平缓。本研究结果说明,草方格沙障对土壤定向培育呈现为正向反馈,为采用草方格促进工程沿线生态恢复和重建提供了理论支撑。
英文摘要	The temporal variation of soil nutrients in the area of straw checkerboard barriers in water diversion project in the Gurbantunggut Desert were investigated using conventional statistics to provide information for land management and control of environmental issues. The soil samples (0 to 40 cm) within the area of straw checkerboard barriers setting with different years were collected in July of 2011, and analysis was made on organic matter, available nitrogen, available phosphorus and available potassium. The results showed that the contents of soil nutrients were affected by straw checkerboard barriers and increased with the years of the straw checkerboard barriers, specially the increase of available nitrogen, available potassium is obvious. The positive feedback mechanism of straw checkerboard barriers for improving the soil quality was observed in this study which provide important scientific basis for the ecological restoration in water diversion project in the Gurbantunggut Desert.
