- Aiming at the ecological environmental deterioration of bashang , from 2002years to3 ~ 5months of 2003 years . sand - transporting quantity of land cover types were on - the - spot moinitoring in gale seaon , comparing the productivity of the main crops . improving environment and developing economy are compositively considered for applying returning cultivated to woodland and grassland to supply the base of theory and technology . the main results as following : 1 observing the sand transporting quantity of artificial grassland , stubble land and cultivate land . indicates that when wind speed is higher ( 8 . 0m / s ) , the sand transporting quantity of artificial grassland of 200cm reduces 35 . 5 % in average more than that of cultivate land , 34 . 5 % sand - transporting quantity than that of stubble land . no distinct difference between stubble land and cultivate land . and when wind speed is lower ( = 5 . 0m / s ) , the sand - transporting quantity of coverage is no distinct difference according to the analysis of variance
从改善环境和发展经济两方面综合考虑，为实施坝上地区“一退双还”提供了理论与技术依据。主要研究结果如下： 1对人工草地、作物留茬地及耕翻地的输沙量观测表明：劲风( 8 . 0m s )下，人工草地比对照耕翻地输沙量在200cm高度内平均降低了35 . 5 ，比作物留茬地平均降低了34 . 5 ；作物留茬地输沙量与耕翻地差异不显著；微风( 5 . 0m s )下，不同地表覆被类型对输沙量的影响差异不显著。
