| 摘 要： | 植物形态对其阻沙能力大小具有重要意义.通过对盐池县3种常见沙生植物猫头刺(Oxytropis aciphylla Ledeb)、米蒿(Artemisia dalai-lamae Krasch)和针茅(Stipa capillata Linn)的野外调查,分析了3种3沙生植物群落的主要形态参数与沙舌长度和拦沙面积的相关关系及与其阻沙能力的拟合关系.结果表明:3种沙生植物群落主要形态参数分别与沙舌长度和拦沙面积呈显著相关,猫头刺、米蒿和针茅的高度与拦沙面积相关系数分别为0.759、0.793、0.988,而冠幅宽度和长度与拦沙面积相关系数均达到0.9以上;猫头刺和针茅的拦沙面积和沙舌长度都随着冠幅面积和植株高度的增加呈线性增加,而米蒿则呈幂指数增加,且猫头刺的阻沙能力大于针茅和米蒿.

| Abstract: | The correlations between main morphological parameters of psammophyte communities and sand tongue length,sediment retention area were analyzed through a field investigation of three common shrubs in Yanchi County,Ningxia.And then the fitting relationship between the main morphological parameters and the sand trapping capability was discussed.Result showed that the main morphological parameters of psammophyte communities were significantly correlated with sand tongue length and sediment retention area.The co... |
