公路建设对沿线的生态环境有明显的不利影响,尤其是在水土流失方面。如何运用水土保持工程,有效地防治公路工程的水土流失,探索出一条公路建设与社会经济、环境协调发展的途径是南方高速公路建设过程中亟待解决的问题。以清连一级公路升级改造(高速)工程为例,对南方高速公路建设项目产生水土流失的因素和土壤侵蚀的特点进行分析,并提出管理措施与工程措施、植物措施及临时措施相结合的水土流失防治体系,有效地控制公路建设的水土流失。
Highway construction has obvious adverse impacts on the ecological environment along the route, especially in terms of water and soil loss. How to use soil and water conservation project to effectively control soil and water loss in highway projects and to explore a way for coordinated development of highway construction, social economy and environment is an urgent problem to be solved in the construction of southern expressway. Taking Qinglian Class I Highway Reconstruction (High Speed) Project as an example, this paper analyzes the causes of soil erosion and the characteristics of soil erosion in the construction of the Southern Expressway and proposes the combination of management measures and engineering measures, plant measures and temporary measures Soil and water loss prevention and control system to effectively control soil and water loss in highway construction.
