Design Of Integrated Constructed Wetland Landscape Planning To Ascend

Integrated Constructed Wetland are a type of wetland that is built and controlled by human resources.It has a strong ability to purify water while taking into account the landscape and science.In recent years,with the increasing demand for living environment,Integrated Constructed Wetland have been widely used due to their excellent purification capabilities.However,there are still many mixed artificial wetlands that have neglected their landscape science in design and post-operation and maintenance,and widely used engineering methods were also bringing the realization of synthetic wetland landscape functions a considerable impact.Considering the above problems,this paper researched the overall artificial wetland landscape improvement,and the main contents are as follow:(1)Taking the comprehensive artificial wetland of the Beijing Wildlife Rescue and Breeding Center and the artificial wetland of the Olympic Forest Park as an example,the field investigation and analysis of the landscape status and purification capacity were carried out,and summarized on the premise of ensuring that the water purification capacity of the constructed wetland does not decrease.The advantages and disadvantages of the improvement of the elements of the artificial wetland landscape.(2)Summarize the design principles and key points of the general artificial wetland landscape upgrading.The design principles include the principle of non-declining purification ability,the law of coordination,the policy of comprehensiveness and the principle of locality.The design points include the improvement of the plant landscape from the construction of colored and seasonal plant landscapes and the cultivation of bird-inhabited plants under the premise of ensuring that the purification capacity of the integrated constructed wetland is not reduced;from the pond waterscape construction and shore waterscape construction Aspects to enhance the water landscape.Enhance animal landscapes from the construction of bird habitats,habitats for benthic and amphibians.The design of landscape sketches has been enhanced from the design of popular science sketches and the design of human elements.(3)Combining the previous research,the design of the landscape improvement method for the HANSHI bridge Integrated Constructed Wetland was designed.Among them,the plant landscape is the focus of the improvement,including: under the premise of dense planting of landscape water plants,the plants of the three colors of red,yellow and white,such as reeds and cattails,are replanted by the step-by-step pond;Honey plant such as yellow iris,yarrow,spirulina,horseweed and bird inhabiting plants such as reed and water onion;wetland repellent plants such as white iris;according to monitoring,the proportion of nitrogen and phosphorus in sewage,to carry out the corresponding planting with landscape and water purification capacity;and to consider the fine management of plants.The upgrading of the water landscape includes the addition of ecological floating islands,and springs,and other facilities with landscape and water purification capabilities;and the construction of viewing ports.Animal landscape enhancements include artificial bird nests,water-based stone construction,and regular refurbishment.The improvement of landscape sketches includes the promotion of comprehensive wetland science popularization cards,bird science exhibition cards and signage systems.Therefore,this paper proposes that the construction of integrated constructed wetlands should be carried out(1)color and season matching of water purification plants,planting of mosquito repellent plants,and fine management of plants to enhance plant landscape;(2)springs,waterfalls,The construction of ecological floating islands and viewing gates enhances the water landscape;(3)the cultivation of food source honey source plants and the habitat of birds and benthic amphibians to enhance the animal landscape;(4)popular science exhibition cards,signs and the construction of sketch sculptures to enhance the landscape.Integrated Constructed Wetland that achieves the above objectives cannot only achieve its purpose of purifying water quality,but also enhance its comprehensive functions in landscape and mission,and improve the complete integrated artificial wetland function.
