摘　　要：近自然陆域环境是公路建设的重要载体。高速公路建设中,需要在不损害交通安全性和时效性的前提下,实现生态安全、生物多样性与人类社会文化环境的互相融合。研究结合国家中长期规划、公路建设发展趋势及近自然陆域生态景观的产生,分析了公路建设对近自然陆域环境的生态影响,提出了公路生态设计准则。G40崇启高速崇明段所处的崇明国际生态岛,是一个高度人工化的景观系统,是典型的近自然陆域环境。结合崇明岛生态本底,介绍了近自然陆域环境下公路生态建设的7个准则和公路生态实现的4个路径。Approximate nature land environment is an important carrier of highway construction. During expressway construction, ecological security, biodiversity and human society cultural environment should be merged together on the premise of the security and timeliness of transportation. Based on the national medium and long-term planning, road construction trends and the generation of approximate nature ecolandscape, the ecological impact of highway construction on approximate nature land environment is analyzed, and the highway coo-design criteria are presented. Chongming international ecological island, where G40 Chongming- Qidong Expressway （the Chongming segment ） is located, is a highly artificial landscape and a typical approximate nature land environment as well. According to the Chongming Island＇s ecological background, 7 criteria for highwany ecological construction and 4 path to achieve highway ecology in approximate nature land environment are introduced.
