摘 要:
【目的】探讨人工结皮在黄土山区公路边坡的应用效果。【方法】选用吕梁山区人为破坏过的公路边坡进行治理,设置5个试验组(T1自然边坡、T2结皮、T3结皮+肥料、T4结皮+种子、T5结皮+肥料+种子)。对每个试验组的土壤温湿度、土壤细沟侵蚀、植物生长状况(植物出苗株数、覆盖度、Shannon-weaver多样性指数、Shannon-wiener多样性指数和Pielou均匀度指数)和生物量进行观测。【结果】结果表明,人工结皮与自然边坡比较,春季结皮可以显著(P<0.05)提高土壤的温度和湿度,雨季结皮能够维持土壤的温度,正午结皮温度显著低于自然边坡的,全天结皮组的土壤湿度显著高于自然边坡,其中T5的土壤湿度最大;公路边坡受雨水的侵蚀程度存在:T5

摘 要:
【Objective】The aim of the study was to evaluate the application of artificial crust in the highway slope of loess mountainous area. 【Method】In the highway slope of the Lvliang mountains,5experimental groups(natural slope(T1),crust(T2),crust and fertilizer(T3),crust and seeds(T4),curst,fertilizer and seeds(T5))were set.Temperature and humidity of soil,rill erosion of soil and plant growth condition(plant emergence,coverage,Shannon weaver diversity index,Shannon wiener diversity index and the Pielou evenness index)were investigated.【Results】Compared with the natural slope,artificial crust increased soil temperature and humidity in Spring and maintained soil temperature in the rainy season.The temperature of crust was significantly lower than that of the natural slope at noon.Soil moistures of crust groups were significantly higher than that of natural slope throughout the day and T5 was the highest.The order of erosion degree was T5
