We have observed the structure of these dune sands and analyzed the grain-size,surface textural features and several main chemical elements of them,the results showed that:(1) these dune sands have some eolian structure characteristics which are similar to the recent dune sands;(2) they are also similar to the recent dune sands in grain-size components,and parameters of Mz,?滓,Sk and Kg,as well as in several main chemical components;(3) the scatter plots of Mz-?滓,SiO2-Al2O3+TOFE and the probability curves of grain-size showed that these paleo dune sands are different from paleosols and fluvio-lacustrine facies but are consistency with recent dune sands;and(4) the quartz sands have well roundness and some surface textural features such as dish-shape pits,crescent-shape pits,pockmarked pits,upturned cleavage plates,siliceous precipitates and siliceous crevasses,indicating that they had been carried for a long time by the wind.

对这些沙丘砂的沉积构造观察以及粒度、扫描电镜和常量化学元素分析结果表明：(1)这些沙丘砂具有与现代沙丘砂相似的风成沉积构造特征；(2)粒度及其参数--Mz、σ、Sk和Kg，以及主要化学组分SiO2、Al2O3和TOFE也与现代沙丘砂相近；(3)Mz-σ、SiO2-Al2O3+TOFE散点图和概率累积曲线显示这些沙丘砂与萨拉乌苏组中的河湖相、古土壤差别明显，而与现代沙丘砂一致；(4)石英砂颗粒具有良好的磨圆以及碟形坑、新月形坑、麻坑、上翻解理薄片、硅质沉淀和硅质裂纹等表面结构特征，反映其曾受持久的风力搬运作用。

This study provided the analysis of changes of species diversity and productivity in relation to soil properties in six typical habitats （wet meadow, dry grassland, fixed dune, semi-fixed dune, semi-shifted dune, and shifted dune） in Horqin Sand Land.

研究了科尔沁沙地6个典型生境类型的沙质草地群落物种多样性与生产力的变化，分析了植物群落格局、物种多样性、生产力与土壤特性的关系。

The field experiments on the near surface airflow, sand transport rate, grain size of the dune sands and the morphology of the dunes show that though shear velocity decreased at the toe of the transverse dune, the threshold shear velocity decreased simultaneously. The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune.

对简单横向沙丘表面的气流、输沙率、物质结构，以及形态学特征的观测表明，在横向沙丘迎风坡坡脚尽管剪切速度有所下降，但起动剪切速度同时减小，起动剪切速度减小与不饱和风沙流是沙物质在迎风坡坡脚不能产生沉积的主要原因。
