公路建设对名木古树的影响及其保护措施—以南岳高速衡山县城连接线为例

Abstract

公路建设的生态环境影响是多方面的，项目永久占地会造成土地上原有植物的消失，常见的人工植被可在砍伐后采取异地恢复等措施来进行生态补偿，但名木古树等具有特殊的价值和意义，需进行特殊保护。本文分析了公路建设对古树的影响，对常见的保护措施进行了总结，以衡山县城连接线项目为例，选取了最为合适的方式对项目涉及的古树进行了有效保护，对同类项目具有参考价值。 Highway construction affects the ecological environment in various ways. Permanent occupation of land causes the disappearance of the original plant; some common artificial vegetation can be recovered in other places after they are felled, which compensates the ecological damage. However, the ancient and rare trees have specific value and significance, so they need special protection. This paper analyzes the influence of highway construction on ancient and rare trees, and summarizes some frequent protective measures. Moreover, it takes Hengshan-Nanyue highway connecting line project as an example, and selects the most suitable way to effectively protect the ancient and rare trees involved in the project. Conclusions have reference value to similar projects.
