公路护坡生物土壤结皮防护研究进展

RESEARCH PROGRESS ON THE BIOLOGICAL SOIL CRUSTS OF HIGHWAY SLOPE

本文对生物土壤结皮的构建、对环境的影响及其对公路护坡的作用等方面进行分析,综述生物土壤结皮防护公路护坡目前存在的问题,并提出建议。主要结论如下:相比于工程护坡,生物土壤结皮具有更高的生态价值,能够促进护坡生态系统的构建与长效发展。与植被护坡不同,生物土壤结皮更能改善土壤养分并提高可利用率,可持续发展能力进一步提升,将生物土壤结皮耦合科学植被防护将强有力助力公路运行过程中的“碳达峰,碳中和”。

This paper analyzes the construction of biological soil crusts,its impact on the environment and its effect on highway slopes,summarizes the current problems of soil biocrust protection highway slopes,and puts forward suggestions.The main conclusions are as follows:Compared with engineering slope,soil biocrust has higher ecological value and can promote the construction and long-term development of slope ecosystem.Different from vegetation slope,soil biocrust can improve soil nutrient and availability,and further enhance the ability of sustainable development.Combining soil biocrust with scientific vegetation will strongly help the“carbon peak and carbon neutral,”in the process of highway operation.
