摘  要:
通过对光梗蒺藜草在固定沙地、流动沙地、半固定沙地、半流动沙地4种沙地类型中作用的分析,表明光梗蒺藜草为半固定沙地上的优势种,其相对盖度和重要值均高于其他3种样地类型,占主导地位;通过Shannon多样性指数分析表明光梗蒺藜草有导致半固定沙地物种多样性减弱的趋势。进一步的研究应更注重光梗蒺藜草在半固定沙地的入侵趋势。

摘  要:
The invasive potential of Cenchrus calyculatus Cav. in the fixed sand,mobile sand,semi-fixed sand and semi-shifting sand was studied. C. calyculatus was the dominant species in the semi-fixed sand,with a relative coverage and importance value higher than the obtained in the other three types. Based on Shannon diversity indices C. calyculatus led to a reduced species diversity in semi-fixed sand. Further research should pay more attention to the invasiveness of C. calyculatus in the semi-fixed sand.
