乌兰布和沙漠地区白刺下沙土粒径分析

Analysis of Sand Particle Size of Ulan Buh Semi-fixed and Fixed Nitraria tangutorum Bobr

文章通过对乌兰布和沙漠地区白刺下(Nitraria tangutorum Bohr.)沙土进行采样,测定其各粒级的百分含量,并与乌兰布和沙漠中梭梭(Haloxylon ammodendron Kief.)、油蒿(Artemisia ordosica Krasch.)、柽柳(Tamarix taklamakanensis M.T.Liu)下沙样及流沙各粒级的百分含量进行对比分析,从而找出白刺下沙土各粒级分布的规律及其与乌兰布和沙漠其他植被下沙土粒级分布规律的差异。

Through determining the percentage of its various grades to carry on the sampling about the sandy soil of the brush piles in Wulanbuhe and fixed half fixed Nitraria （Nitraria tangutorum Bobr.）, And carrying on the contrastive analysis of various grades＂ percentage of the Sandy soil sample and wind-drift sand of ？Haloxylon （Haloxylon ammodendron Kisf.）, oil of Artemisia （Artemisia ordosiea Krasch. ）,and the Tamarix （Tamarix taklama kanensis M.T. Liu） in Wulanbuhe desert, Thus that the grades distributed rule of wind-drift sand of sandy soil sample of the brush piles of Nitraria and other vegetations sand material grade distributed difference under Wulanbuhe desert is obtained.
