Study On Plant Disposition Of Urban Wetland Park

Wetlands are a transitional zone between the water and the land.In wetlands,the animals,plants,and microbial species are rich,and it's one of the important ecological environment on the earth.Wetland park is a special form of wetland,and plants are the foundation and core of wetland park.Scientific and rational allocation of wetland plants is conducive to the formation of beautiful plant landscape and wetland park sustainable development.This paper took Longhu National Wetland Park in Huaiyang as the research object,in order to improve the ornamental value and ecological value of city wetland park,on the basis of field investigation,using the index analysis method,I comprehensively analyzed the advantages and disadvantages of the plant arrangement of Longhu National Wetland Park in Huaiyang.The main results were as follows:1.Studied the species,distribution,ornamental characteristics and phenological period of the plants in Longhu National Wetland Park in Huaiyang.The results showed that the plant species were rich,flowering plant species were numerous and rich in color,but the plant distribution was uneven,and the available shrubs species were few.There were basically no ornamental varieties in winter.2.Analyzed the plant allocation current situation and pointed out its existing problems.The results showed that plant species were rich,the configuration was diversified,and the plants were strong observability.The plants were in good condition with color,and they were reasonable with the surrounding environment.But the trees were used less,the collocation of trees,bushes and grass was unreasonable and was an unbalanced ecosystem;common species were intensive,landscape similarity was high.In the late winter and early spring,landscape was depression,as well as alien species were breeding,these problems directly caused the decline in plant landscape within the wetlands.3.Proposed the plant selection criteria and plant allocation principles.The plant selection should be in accordance with these three criteria: the appropriate tree,the ability to clean the environment,and high ornamental value,so as to optimize the good ecological benefit and landscape effect tree species.The plant configuration should follow the principles of comprehensive consideration trees,bushes and grass,and pay attention to the principle of seasonal change,and consider the various factors,and arrange the plant community model with high ornamental value and good ecological benefit.4.Obtained the plant allocation pattern.On the basis of the above research,this paper put forward the transformation plan for important areas,and obtained the suitable plant allocation pattern for the wetland park in Longhu National Wetland Park in Huaiyang,such as wetland trees and wetland ground,the pattern can form the open forest space;submerged plants + water plants,for this configuration mode,the water plants are the viewing focus,submerged plants need to have water purification effect;submerged plants + floating leaf plants + water plants,for this configuration mode,the floating leaf plants and water plants are the viewing focus,coupled with the purification of submerged plants,plant beauty can be better with the water into one.In addition,wetland plant conservation and management efforts should be increased,and strive to create a harmonious,ecological plant landscape.
