The Application And Researches Of Aquatic Plants In The City Landscape Construction

Because of aquatic plants with ornamental value, economic value, ecological value and the characteristics of environmental benefits, so as the city development and control of the construction of ecological garden, river, and the rise of the wetland park it in the important position of waterscape landscape application continuously emerging, and aquatic plants become indispensable in the modern city landscape gardening landscape material, in the modern material civilization and spiritual civilization construction, play a positive role, and its application methods, the scope and variety development and are more and more get the wide attention from all walks of life.In recent years, korla to use its own through the city is the only river in xinjiang city of independence day thick geographical advantage, to strive to build "water city", to organize the implementation of the "three rivers will converge" water system landscape engineering, do their "big water", carry water system of urban landscape features and cultural connotation, the formation of city water dependent features of urban landscape water landscape.Based on the field investigation concluded that:in Korla area, development, cultivation and application of aquatic plant behind the vigorous development of the construction of the ecological environment of city. Experimental observations:Introduction aquatic plant leaf expansion period mostly concentrate on 4 months later; Blossom beginning period of 5-6 months, the color is rich and colorful is water lily, the lotus and the aquatic canna; The annual growth period is relatively long, growth days reached more than 165 days of aquatic plants with Typha, water lily, Huang Changpu, water, reed candle; The florescence is longer, the number of days to reach 90 days or more blossom aquatic plants are water lilies, aquatic Canna, Lythrum salicaria, Nymphoides peltatum. According to the observation data content summed up the mode of reproduction, planting density, living habits, to better understand the maintenance management techniques. Fast heating up in the local area in spring and summer, sand, dry hot wind drying with other harsh climate conditions, The highest frequency of application for local cattail and reed with strong resistance, plant maintenance management easy local varieties; Lotus flowers and bright, beautiful gesture, in the scope of application of the local area and wide, but on a small scale, mainly especially the flowering period is relatively short, on the growth of environmental sensitive, management is not easy. By the hierarchy analysis of aquatic plants of the introduced method for screening that:Typha, Scirpus validus, Lythrum salicaria, Huang Changpu, Nymphoides peltatum, water lily, water candle and reed varieties available in the local area of large-scale promotion and application; Then spent force, Canna generalis and crankshaft Sparganium of illumination and other environmental requirements higher, in the local area can be small area planting, as embellishment application plays a better effect of landscape; Lotus can strengthen management, small area planting, papyrus needs further experimental observation. Finally, combining with the characteristics of city water body and landscape requirements, on the basis of full investigation and study, landscape water body landscape of korla configuration mode of case analysis, put forward different waters form configuration method, recommend suitable city water plants in the development of the region and its typical water plant configuration mode, and discusses the matters needing attention of water landscape, urban water landscape for the future of reasonable plant building foundation, and then create a rich variety of plant community waterscape, play to their landscape and ecological benefits, to create "water city", rich urban garden water features, improve the urban environment has important practical significance.
