盐碱土地区的特点是:植被稀少,土壤蒸发强烈,地下水位高,地力贫瘠。公路绿化,不仅能巩固路基,美化路容,舒适行人,同时对盐碱土地区的低质量的生态环境和条件,可起到综合改良的作用。盐碱地公路植树具有不少明显的优点: 1.公路本身需要绿色植物的陪衬和调节,尤其是公路的标准化、美化建设,更离不开绿色植物的衬托; 2.公路绿化能起到巩固路基,降低地下水位的作用; 3.公路绿化可净化空气,减少污染,增进身心健康;
Saline-alkaline soil area is characterized by: rare vegetation, strong soil evaporation, groundwater level is high, poor soil fertility. Highway greening can not only consolidate the roadbed, beautify the road capacity, comfort pedestrians, at the same time on the saline-alkaline soil area of low-quality ecological environment and conditions, can play a comprehensive improvement role. Saline-alkali highway tree planting has many obvious advantages: 1. The highway itself needs the foil and adjustment of green plants, especially the standardization and beautification of the highway construction, which can not be separated from the green plants. 2. Highway greening can consolidate the roadbed, Reduce the role of groundwater level; 3. Highway green can purify the air, reduce pollution, improve physical and mental health;
