公路绿化中原生植物利用的筛选方法探讨——以山西省阳城市为例

The Discussion on the Screening Method of Native Plants Utilization in Highway Greening——Taking Yangcheng City in Shanxi Province As An Example

以山西省阳城市为研究对象,以公路绿化中原生植物的筛选为研究目的,对阳城绿道、省道229阳城段、蟒河国家自然保护区3处区域沿线的原生植物种类运用样线调查法进行调查,并根据公路乡土植被恢复及景观绿化配置中对乡土植被种类的需求从生境适应性、水土保持、固碳与污染物吸附、景观营造、繁殖培育、养护管理等方面确定原生植物的筛选原则,筛选适用于阳城市公路建设的原生植物种类,为阳城市公路生态绿化中乡土植被的生态恢复与景观营造提供重要的选择,为国内公路生态绿化建设中原生植物的筛选提供切实可行的参考依据。

The paper investigated the native plants species along the three areas of Yangcheng Green Road,Provincial Road 229 Yangcheng Section,Manghe National Nature Reserve.According to the highway native vegetation restoration and the demand for local vegetation species in landscape greening configuration,it also determined the screening principles for native plants from the aspects of habitat adaptability,water and soil conservation,carbon fixation and pollutant adsorption,landscape construction,breeding,conservation and management,etc,which was suitable for the native plants species of urban highway construction in Yangcheng city,provided an important choice for the ecological restoration and the landscape construction of the local vegetation in the ecological greening of the urban highway in the Yangcheng city,and also provided a feasible reference basis for the selection of native plants in the domestic highway ecological greening construction.
