Comparative Analysis of Soil Matrix Characteristics in Different Ecological Restoration Techniques of Expressway Slope
This paper takes the experimental slope of Qiwu high-speed vegetated concrete and guest soil for ecological restoration as the research object,and analyzes the soil matrix nutrients and physical characteristics of the ecological restoration slope after one year of construction,revealing the differences in the contents of hydrolyzed nitrogen,organic carbon,available phosphorus and available potassium in the soil matrix of different ecological restoration methods after the vegetation growth season.The particle size of different soil samples was analyzed to compare their physical structure characteristics.The results show that the soil matrix nutrients of the vegetated concrete slope are higher than those of the guest soil sprayed slope.The soil nutrient content showed obvious spatial differences on the slopes.The higher nutrient content was hydrolyzed nitrogen,organic carbon and available phosphorus at the slope bottom,and the higher nutrient content was available potassium at the slope top.The particle size composition level of vegetated concrete soil is larger than that of the average soil particle diameter sprayed by the guest soil.
