一、概况目前,全世界已有80多个国家和地区拥有高速公路,通车总里程超过了23万千米。当高速公路为人类带来巨大效益的同时,也对自然景观和生态系统带来了负面影响。建设过程中大规模的开山采石、取土以及大量弃土弃渣,使原生植被遭到破坏,进而加剧了水土流失,引发了一系列环境问题,使路域范围内的生态环境遭受较大的干扰和破坏,严重的可导致生态环境的恶化。因此公路建设植物防护对于边坡稳定和改善区域生态环境起到很重要的作用。二、公路边坡植物防护的作用植物边坡的主要作用在于植物根系对土壤的
I. Overview At present, there are more than 80 countries and regions in the world owning expressways with a total mileage of more than 230,000 km. When highways bring great benefits to human beings, they also have a negative impact on the natural landscape and ecosystem. In the process of construction, large-scale mountain quarrying, earth borrowing and a large amount of abandoned spoil have damaged the native vegetation and further aggravated water and soil loss, triggering a series of environmental problems that have caused the ecological environment in the road area to suffer greater The interference and destruction, serious can lead to the deterioration of the ecological environment. Therefore, the plant protection of highway construction plays an important role in slope stability and improving the regional ecological environment. Second, the role of roadside plant protection The main role of plant slope is the root system of plants on the soil
