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。
The studies on land degradation problems in the process of highway construction and operation are mainly focused on the unilateral analysis of land occupation, soil erosion, soil pollution and land quality deterioration. The study of soil erosion is the important part, including scale, mechanism, regularity and forecasting methods. Heavy metal pollution of soils is the main focus in soil pollution research, and the physicochemical property is the main focus in soil quality deterioration, while the research on soil biological property is relatively scarce. The studies on land degradation problems due to highway construction and operation severely lag the speed of highway construction in China, and further research should focus on the study of land degradation, evolution and restoration in the process of highway construction and operation, the systematic analysis of regularity of soil erosion and development along highway, the study of soil resource conservation and utilization and techniques and standard of economical and intensive use of land for road construction.
