摘要: [目的] 研究不同材料和质量的植被毯在高速公路边坡绿化中的保水效果,为合理使用植被毯技术提供依据。[方法] 采用侵蚀槽填土布设不同质量(100~500 g/m2),不同材料(麦秸秆、椰丝纤维)的植被毯,模拟施加措施的公路边坡,并设置无覆盖对照组。使用侧喷式人工降雨仪器进行降雨试验,测定不同时段径流量和入渗量的变化。[结果] 麦秸秆组和椰丝纤维组较之对照组,其径流量明显减少,入渗量显著增大。麦秸秆植被毯比椰丝纤维植被毯入渗性能更好。麦秸秆组300 g/m2的植被毯和椰丝纤维组200 g/m2植被毯保水效果在同种材料植被毯中最为突出。[结论] 植被毯能够起到显著的保水作用,保水效益因材料和质量变化有所区别。建议施工中使用300 g/m2的麦秸秆植被毯。

Abstract: [Objective] The aim of the study was to compare the water retention capacity between vegetation carpets with different materials and quantities.This can provide a basis for effective use of side slope vegetation carpet technology. [Method] The artificial rainfall system of lateral spraying was used to simulate rainfall.The experimental had several vegetation carpet types with different quantities (100-500 g/m2) and materials (wheat straw and coconut fiber) and the control group was the slope without any measures.The runoff volume and infiltration were measured during different periods. [Results] There were significant differences in slope runoff between the experimental and control groups.The slope runoff of vegetation carpets were significantly lower than that of the control slope but the opposite was true for infiltration.The vegetation carpet of wheat straw had a better infiltration performance compared to the coconut fiber.The vegetation carpet of wheat straw within 300 g/m2 had the most prominent water retention effect among the same material but the water retention was the best for coconut fiber within 200 g/m2. [Conclusion] Vegetation carpets have significant effects on water retention;the water retention benefit varied from different materials and quantities;the vegetation carpet of wheat straw fiber (300 g/m2)is recommended in construction.
