Study On Plant Landscape Quality Evaluation And Optimization Of Qiandao Lake Scenic Road

The development of scenic byway rises in response to the proper time and conditions,and gradually becomes a new linear tourism carrier that pays equal attention to traffic and scenic experience.The construction of the scenic byway around Qiandao Lake is the key point of the strategy of Healthy and Beautiful Qiandao Lake,and the Qianfen Road is the most important section of the scenic byway around Qiandao Lake,which has demonstration significance.The background of plant landscape of Qianfen Road is mainly natural secondary forest and artificial planting community formed by closing mountains and cultivating forests,which is a kind of corridor from the perspective of landscape ecology.With the framework of landscape ecology degree and analytic hierarchy process,eleven evaluation factors are derived from the three aspects of ornamental characteristics,ecological characteristics and psychological characteristics,and the weight of evaluation index is obtained.From the perspective of corridor,the overall evaluation shows that the plant landscape of Qianfen Road has zonal characteristics,rich green and good green comfort,but there is a lack of diversity,spatial level,color and seasonal changes,leading to a significant lack of excitement.On the basis of this,the optimal idea of scenic byway is put forward by using the principle of natural succession and artificial promotion succession.Based on the field investigation and the consultation of local relevant departments,eight patches are selected for evaluation,and the optimization scheme of color,seasonal phase,spatial level,overall form and species diversity of plant landscape of Qianfen Road is proposed.This paper has certain reference value for the optimization of plant landscape of other scenic byways in Qiandao Lake and rural landscape road.
