摘要
为了减少太行山地区由于道路修建对生态的影响,响应生态恢复是保证绿水青山就是金山银山理念的实施,以道路景观、土木工程、植物学等理论为基础,分析适合太行山高速邯郸段道路两旁植物与吸收二氧化硫量、抗寒、根系长度的相互关系,得到:加拿大杨、臭椿、紫丁香、山楂等吸收SO2的能力较强;核桃、山楂、大叶黄杨抗寒性较强;加拿大杨、臭椿植物根系长度较长。应用多目标决策理论构建了植物的净化能力、抗寒能力以及固土能力的物种多目标决策函数,最终确定了加拿大杨为最优,其次为连翘、紫丁香,为生态恢复植物的选择提供了一种新的思路。
In order to reduce the impact of road construction on ecology in Taihang mountain area,the response to ecological restoration is to ensure the implementation of the concept that green water and green mountains are golden mountains and silver mountains.Based on the theory of road landscape,civil engineering,botany and other theories,this paper analyzes the relationship between the plants on both sides of the road suitable for Handan section of Taihang mountain expressway and the absorption of sulfur dioxide,cold resistance and root length,and obtains:Canadian poplar,toona,lilac and hawthorn have strong ability to absorb SO2;walnut,hawthorn and boxwood have strong cold resistance;Canadian poplar and toona have long roots.Based on the multi-objective decision-making theory,the multi-objective decision-making function of plant species for purification ability,cold resistance ability and soil fixation ability was constructed.Finally,Canadian poplar was determined as the best,followed by forsythia suspensa and lilac,which provided a new idea for the selection of ecological restoration plants.
