摘　　要：采用生态调查方法,对京承高速公路中央隔离带、边坡、服务区等不同功能区的植物组成和配置模式进行特点与效果分析。分析显示:目前高速公路选用绿化植物种类达38种,隶属于18个科;各个功能区植物配置各有特点,边坡选用植物以豆科为主,耐旱并且具有良好水土保持功能;中央隔离带植物则以防眩和引导行车视线为主;护坡道和碎落台选用的植物根系发达,能够有效提高边坡稳定性;收费站和服务区选用植物主要起隔音防尘,美化环境的作用;互通桥区配置的植物主要引导行车视线,提高行车安全性。胡枝子、紫穗槐、臭椿以及火炬树是该区域的优势物种,豆科、菊科、漆树科植物在该区域具有较强的适应能力。继续加强植物选择与应用的研究将会对公路绿化产业的发展产生巨大推动作用。Take advantage of ecological survey method to analyze the effect of application through the plant species composition and configuration mode in different functional areas of the Beijing-Chengde expressway(Part III),such as the slope,center median divider,service area and so on.The results show that the Beijing-Chengde expressway(Part III)has selected 38 species of green plant belonging to 18 families currently.Plant configuration of the various functional areas have their own characteristics,slope plants mainly chosen in leguminous,drought-proof,with good performance of soil and water conservation;median strip use plant which has the function of anti-dazzle and direct the eye;rubble slope and gravel pavement chosen the plants'root which can improve slope's stability effectively;toll stations and service areas selected plants with function of sound-proof or dust-proof,meanwhile taking the landscaping role;the interoperability bridge area's plant configuration mainly induced traffic,improve traffic safety.Lespedeza,Amorpha,Ailanthus and Rhus typhina are the dominant species in this district.Leguminosae,Asteraceae and the Anacardiaceae plants in this region have better adaptability.Furthermore,strengthen plant selection and application of research will produce a huge role in promoting the development of highway greening industry.
