选择百花山公路边坡不同生态恢复措施(喷混植生、客土种植、营养土种植、三维网种植、六棱砖种植)的生态系统为研究对象,以稳定的自然植物群落作为对照,研究不同生态恢复措施对土壤理化特性的影响。结果表明:在土壤养分和土壤微生物含量方面,不同恢复措施样地之间差异显著,营养土种植样地含量最高,三维网种植和喷混植生样地次之,客土种植和六棱砖种植样地最低;对比土壤脲酶活性,营养土种植、三维网种植和喷混植生恢复样地与自然植物群落样地差异不显著,但显著高于客土种植和六棱砖种植样地;在土壤生物学和土壤养分相关性方面,土壤微生物量碳、氮含量和脲酶活性与土壤全氮、速效氮、有机质等呈显著正相关,与全钾含量呈显著负相关。
The ecological system of Baihuashan Highway Slope with different ecological restoration measures (spray mixed planting, guest planting, nutritious soil planting, three-dimensional net planting and hexagonal brick planting) was selected as the research object and the stable natural plant community was taken as the control to study the differences Effects of Ecological Restoration Measures on Physical and Chemical Properties of Soil. The results showed that in the aspects of soil nutrient and soil microbial content, there were significant differences among different restoration measures plots, with the highest content of nutrient soil planting plots, followed by three-dimensional net planting and spray planting, Compared with the soil samples, the soil urease activity, nutrition soil planting, three-dimensional net planting and spray mixed planting and restoring plots and the natural plant communities were not significantly different, but significantly higher than that of the soil planting and hexagonal brick planting plots; There was a significant positive correlation between soil microbial biomass carbon and nitrogen, urease activity and soil total nitrogen, available nitrogen, and organic matter, and a negative correlation with total potassium content.
