Ecological Corridor Renovation of Longliwen Expressway Based on the Utilization of Native Trees
In order to improve the forest landscape effect of the ecological corridor on the expressway,a beautiful ecological corridor forest community evaluation index was established.After investigating the vegetation status of the Longliwen Expressway corridor,it was found that years of artificial management have changed the natural vegetation characteristics of the forest.Based on the law of forest succession,it is proposed to fully utilize native trees species and adopt measures such as thinning,replanting,and targeted nurturing for different communities to increase the number of local broad-leaved tree species with obvious levels,leaf colors,flower colors,and fruit col-ors within the forest community;Planting fire-resistant broad-leaved tree species in areas prone to forest fires;The construction goal is to eliminate foreign harmful organisms and protect biodiversity.By transforming and con-structing different landscape patches,a heterogeneous landscape with spatial and temporal changes is formed.Va-rious landscapes are embedded with each other,with obvious seasonal changes,forming a rich and colorful,aes-thetically valuable,and ecologically functional beautiful ecological corridor landscape.
