青藏高原植草固沙措施研究

Study on planting grass sand-fixing measures in inghai-Tibet plateau

针对青藏高原日益严重的风沙灾害,通过分析青藏高原沙漠化及风沙灾害的影响,对植草固沙措施进行研究,为提高植草固沙措植株成活率,结合当地自然条件设计合适的植生基质配比;选择种植冷地早熟禾、披碱草、老芒麦。对植草固沙措施效果及自然生长植被进行研究后认为:人工种植植物生长高度及密度均优于自然生长植被;植草固沙措施既能治理风沙又能改善生态环境。

In view of the increasingly serious sandstorm disaster in the Qinghai-Tibet Plateau, based on the analysis of the desertification and sandstorm disaster of the Qinghai-Tibet Plateau, the sand fixation measures of the grass planting were studied. In order to improve the survival rate of the plant and sand fixation, the suitable planting base ratio was set up according to the local natural conditions. Choose to plant poa crymophila, elymus dahuricus,elymus sibiricus Linn. The results showed that the growth height and density of the plant were better than that of the natural vegetation. The sand fixation measures could improve the ecological environment.
