河源水生植物哪里有批發可以采用人工濕地植物塘床系統，人工濕地塘床系統中的大型水生植物群落是人工濕地生態系統的骨架,起著支撐系統的作用,同時還發揮著凈化、美化、綠化環境的作用。成都的活水公園便是一個成功的案例。 

    6 存在的問題和建議 

    6.1 對水生植物的生態功能不能充分的發揮 

    許多植物種植設計過多地考慮園林美學的要求，忽視了生態系統的建立，一些污水凈化效果好的漂浮植物和沉水植物應用較少。僅使用挺水植物和浮葉植物所建立的水體生態系統是非良性循環的。應在充分考慮景觀的基礎上，必須以建立穩定的生態系統平衡及物種的多樣性為最終目標。 


    6.2 在水生植物的選擇上不顧立地條件和實際情況，隨意使用 

    在人工濕地的植物選擇上，應采用謹慎的態度，因地制宜，選擇適應本地區域的既具較高觀賞價值又能凈化水質的水生植物，盡可能營造出景觀價值與生態意義俱佳的水景。 

它們的生長狀況能直接或者間接反映出某個水域或水體的相應物理、化學及其它環境指標，有利于人們對水質變化的調控。研究結果表明，一些水生植物對水體內的污染物具有相應的去除效果。如：鳳眼蓮可去除氮、磷、鉛、鋅等元素，苦草可去除砷、銅、鉛、鋅等元素，大藻可去除鉻、鉛、鋅等元素。  1.2水生植物的景觀功能  水生植物不僅可以觀葉、賞花，還可以欣賞其在水中的倒影。通過各種水生植物之間的相互配置，可以豐富景觀效果，創造園林意
境。在以往的園林水景中，應用較多的有荷花、睡蓮、黃菖蒲、菖蒲、香蒲、蘆葦等種類，并不乏有以水生植物為主題的專類水景園。如杭州西湖的”曲院風荷”就因其獨特的荷花景觀而聞名。水生植物已日漸成為江河、湖泊、公園、池塘等水體造景的優良材料  2水生植物在景觀設計中的應用  2.1水生植物材料的選擇  植物材料除了要有較高的觀賞價值外，最好還應具備一定的去污能力，并模擬自然生態環境，達到水體自凈的效果。其中已知比較優良的種類有蘆葦、睡蓮、菖蒲、香蒲、水葫蘆等；同時還可以充分挖掘引種當地的野生水生植物，豐富景觀水體植物配置的內容，為水體綠化、美化提供更多的基礎材料。深圳沃水從事水生植物培育種植與水生態環境修復建設的綜合服務商，是國家級首批高新技術企業，公司是國內最早研究水植物種植培育的企業之一，主營業務為：水生植物銷售，水生植物批發，水生植物基地，水生植物苗場。

The aquatic plant in Heyuan can adopt the artificial wetland plant pond bed system. The large aquatic plant community in the artificial wetland pond system is the skeleton of the artificial wetland ecosystem, plays the role of supporting the system, and also plays the role of purifying, beautifying and greening the environment. The living water park in Chengdu is a successful case.
6 existing problems and suggestions
6.1, the ecological functions of aquatic plants can not be fully developed.
Many plant planting designs have considered the requirements of Garden Aesthetics too much, ignoring the establishment of the ecosystem, and some floating plants and submerged plants with good sewage purification effect are less used. The water ecosystem established by using only emergent plants and floating leaves plants is not a benign cycle. On the basis of full consideration of landscape, we must establish stable ecosystem balance and species diversity as the ultimate goal.

6.2, regardless of site conditions and actual conditions in the selection of aquatic plants, use them freely.
In the selection of artificial wetland plants, we should adopt a cautious attitude, adapt to local conditions, choose the aquatic plants which have high ornamental value and purify the water quality in the local area, and create a waterscape with good landscape value and ecological significance as far as possible.
Their growth conditions can directly or indirectly reflect the corresponding physical, chemical and other environmental indicators of a certain water or water body, which is beneficial to the regulation of water quality change. The results showed that some aquatic plants had a corresponding removal effect on the pollutants in the water. For example, Eichhornia crassipes can remove elements such as nitrogen, phosphorus, lead, zinc, etc., which can remove arsenic, copper, lead, zinc and other elements. Algae can remove elements such as chromium, lead and zinc. 1.2 the landscape function of aquatic plants. Aquatic plants can not only view foliage, admire flowers, but also enjoy their reflection in water. Through the mutual arrangement of various aquatic plants, the landscape effect can be enriched and the artistic conception of the garden can be created. In the past garden waterscape, there are many kinds of lotus, water lily, Huang Changpu, calamus, cattail, reed and so on, and there are no lack of aquatic plants with the theme of aquatic plants. Such as West Lake, Hangzhou, the "courtyard house" is famous for its unique lotus landscape. Aquatic plants have gradually become excellent materials for water landscaping of rivers, lakes, parks and ponds. 2 aquatic plants are used in landscape design. 2.1 selection of plant materials for aquatic plants should have better decontamination ability and simulate natural ecological environment to reach water. The effect of self purification. Some of the better species are reed, water lily, calamus, cattail, water hyacinth and so on. At the same time, we can fully excavate the local wild aquatic plants, enrich the content of plant configuration in the landscape water body, and provide more basic materials for the greening and beautifying the water body.
