The Application Of Aquatic Plant In The Wetland Park Landscape

In recent years, the rapid development of national urbanization has led to the increase of wetland destruction.To some extent, the construction of wetland park has eased the pressure and caused desirable impact on the surrounding environment. But the structure of aquatic plant in wetland park is a little too unitary and little consideration has been taken to the effect on the growth and purification of aquatic plant as well as landscape features. Therefore, in this paper we take the application of aquatic plant in the wetland park landscape as the research object.Besides, we focus on the functions and configuration principles of aquatic plant in the wetland with related case analysis.Finally,taking the case of the Yanghu wetland museum plant in Changsha as a case,we evaluate the original wetland plants schemes and offer the advice to make revisions,on the purposes of giving reference to the application of aquatic plant in wetland park.The main conclusions are presented as follows:(1) The research on the functions and configuration principles of aquatic plants in the wetland and related case analysis:Through the comprehensive analysis of all kinds of aquatic plants and the application of aquatic plants at home and abroad in related wetland park, it is concluded that aquatic plants mainly has the function of water purification and landscape beautification,besides,most of the plants can purify the water. Therefore, reasonably planting and collocating aquatic plants in water can help to absorb the harmful substances in the water and have good effect of improving water quality of eutrophication,so as to achieve the purpose of purifying the water. Aquatic plants landscape effect is rich and colorful and they have unique and artistic conception. The configuration of the aquatic plants should be done according to the demands of water depth and the growth characteristics of plants, following the consistency principle, harmony principle, landscape diversity and landscape ecological principle.(2)Evaluating the original aquatic plant applicate based on the case of yanghu wetland museum in Changsha:At present, the construction of lake wetland museum drainage of aquatic plant community has been basically completed, but the overall effect is not satisfactory.Through investigation and study, we found the following problems:①. The lack of plants quantity and species.②.Too much surface-flowing wetland,in which bacteria accumulate in the root of many plants,what is more,pollution status such as mosquitoes is easy to appear in summer.③The effect of landscape is not significant and can not reflect the diversity of aquatic plant community in wetland museum of ④. The effect of purification and the improvement of the water quality effect are not significant.⑤. The lack of management of plant maintenance.(3) Take the case of Yanghu wetland museum in Changsha as an example to design the original aquatic plants:According to such indicators as wasted water treatment process, water quality, water depth in the wetland museum,we put forword three major ideas:presenting the diversity of aquatic plants species, aquatic plants functions of decontamination and its displaying effect.We propose the renovation design scheme to increase the types of vertical and horizontal undercurrent wetland.According to different the direction of flowing water in the roof of wetland museum and different grades of purification and diversification, the overall plan is divided in turn into three areas. Area of purification function,area of landscape effect and the area of plant diversity. The scheme uses more than 90 kinds of plant species. We use the way of classification and divided them into small pieces and then mix and combine them,so as to reflect the diversity of plant species and community.Moreover, according to the features of building group of plant and the configuration of other plants,we create the pattern of halosols deserts decontamination community. In water, we drive midge plant cell configuration and in the terminal unit we plant algal and sterilizing plants.The introduction of evergreen plants and the configuration of winter combination mode of plant community building landscape type table flow wetland unit help to enrich the seasonal color system. We coordinate the landscape with table flow unit, ornamental line and the overall layout, configure the undercurrent unit plant community.
