【摘要】：对公路建设及运营中所引发的土地退化问题的相关研究成果主要集中于公路占地、土壤侵蚀、土壤污染、土壤性质恶化等单方面的分析:土壤侵蚀是重点研究内容,具体包括土壤侵蚀规模、土壤侵蚀机理、土壤侵蚀规律及侵蚀预测方法;土壤污染以重金属污染为主要研究内容,土壤性质恶化则重点关注于土壤理化性质,土壤生物学性质变化研究相对薄弱。我国公路建设及运营所致土地退化问题的研究严重滞后于公路工程建设,今后应强化公路建设及运营过程中的土地退化、演变及恢复研究,公路沿线土壤侵蚀发生发展规律的系统性研究,土壤资源保护与利用研究,公路建设用地节约集约利用技术和标准研究等。
[Abstract]:The related research results of land degradation caused by highway construction and operation are mainly focused on the unilateral analysis of road occupation, soil erosion, soil pollution, soil property deterioration and so on: soil erosion is the key research content. Soil erosion scale, soil erosion mechanism, soil erosion law and erosion prediction method, soil pollution is the main research content of heavy metal pollution, and soil property deterioration focuses on soil physical and chemical properties. The study on the change of soil biological properties is relatively weak. The study of land degradation caused by highway construction and operation in China lags behind that of highway construction. In the future, the study on land degradation, evolution and restoration in the course of highway construction and operation should be strengthened. The systematic study on the occurrence and development of soil erosion along the highway, the research on the protection and utilization of soil resources, the research on the techniques and standards of saving and intensive utilization of highway construction land, etc.
