- 摘要:
- 为了评估不同天然植被群落类型的防风效应，我们在库布齐沙漠与黄河河岸之间的生态过渡带选取了柠条（Caragana intermedia）、白刺（Nitraria tangutorum）、拂子茅（Calamagrostis ep igejos）、赖草（Leymus secalinus）和芨芨草（Achnatherum sp lendens）等5种常见的天然灌草植被群落以及裸露沙地，并对其防风效应作了比较。结果表明，这几种不同天然植被群落类型的在近地面（10 cm）防风效应从大到小的次序是：赖草群落>芨芨草群落>拂子茅群落>裸露沙地>白刺群落>柠条群落；同一天然植被群落类型不同高度的防风效应也有较大差异；随距离地面高度的变化，不同植被群落风速降低率亦有变化。为干旱、半干旱地区天然植被群落的保护提供了科学依据。
- Abstract:
- In order to evaluate the effect of reducing wind velocity of different natural vegetation,5 natural shrub and grass vegetations,Caragana intermedia,Nitraria tangutorum,Calamagrostis epigejos,Leymus secalinus and Achnatherum sp lendens in the ecotone between the Kubuqi desert and the riverbank of the Yellow River were chosen and the uncovered sand was selected as the comparison.The results showed that the order of the effect(near the ground,0～10 cm) of reducing wind velocity from strong to weak was Leymus secalinus>Achnatherum sp lendens>Calamagrostis ep igejos>uncovered sand>Nitraria tangutorum>Caragana intermedia.And there was a big difference of the ratio of reducing wind velocity among different height of the same natural vegetation.As the height changing,the ratio of reducing wind velocity of different natural vegetation changed.
