【摘要】：新型生态植被毯边坡防护效果良好,目前常用的植被毯种类有椰丝型、麦秸型以及椰丝麦秸混合型。为优选出性价比最高的植被毯材料,对这3种植被毯上建植植被的植被覆盖度、有效根密度、地表径流量、土壤侵蚀量和土壤抗蚀性能进行了对比分析。结果表明,与在自然坡面上建植植被相比,植被毯护坡均可以增加土壤的覆盖度,减少降水的径流量与土壤侵蚀量。结合植被毯的产品质量指标,椰丝麦秸混合型植被毯性价比较高,可以作为普遍推广的植被毯品种。研究成果可为植被毯的施工及推广应用提供一定科学依据。
[Abstract]:The new ecological vegetation blanket slope protection effect is good. At present, the commonly used vegetation blanket types are coconut silk, wheat straw and coconut wheat straw mixed type. In order to optimize the vegetation blanket material with the highest cost performance, the vegetation coverage, effective root density, ground surface runoff, soil erosion and soil corrosion resistance of the 3 planted blankets are built. The results show that, compared with the vegetation vegetation on the natural slope, the vegetation blanket protection can increase the soil coverage, reduce the runoff and soil erosion. Combined with the product quality index of the vegetation blanket, the coconut silk straw mixed vegetation blanket has a high performance price ratio, and can be used as a widely popularized vegetation blanket variety. It can provide a scientific basis for the construction and popularization and application of vegetation blanket.
