乡土植物在广梧高速公路生态绿化中的应用

绿化关系到高速公路的长期效益,是生态高速公路建设的重要内容。广梧高速公路的生态绿化,以利用乡土植物为原则,模拟自然生态系统的组成和结构,实现公路景观与周边自然景观的和谐统一。对广梧高速公路双凤至平台段的自然条件、植被类型及植物种类进行了全面调查,结果显示该地域共有维管束植物342种,隶属于95科244属,然后结合植物本身的生物学、生态学及生理学特征,从中筛选出适于本段高速公路两侧绿化带、边坡绿化的乡土植物53种;并根据沿线具体的生境条件,按照群落学的原则对其组合应用进行了设计。

Application of native plants in the ecological virescence of Guang-Wu Expressway

Greening is an important part of highway constraction and closely related to the its long-term operation. In the ecological greening process of Guang-Wu expressway, native plants were used by imitating the components and structure of natural ecosystems, so to make the highway be in harmony with the natural landscape. First we investigated the natural conditions, vegetation types and plant species along Guang-Wu Expressway (Shuangfeng-Pingtai) by field survey. Statistical result showed that there were about 95 families, 244 genus, 342 species of vascular plants, 53 of which were considered most suitable for ecological restoration of the road side and side slope greening after carefully comparing their biological, ecological, physiological traits. Then, several planting models were designed by phytocoenology principles, to accelerate the process of vegetation restoration.
