Haizhu National Wetland Park Aquatic Plant Investigation And Evaluation Of The Configuration

Nowadays the rapid development of industrialization, led to the deterioration of ecological environment, countries all over the world pay more and more attention to the environment construction and urban greening. Governments are beginning to seek and explore different ways to improve the urban greening environment, provide appropriate leisure entertainment to humans. As one of the urban wetland and form has been widely used. In recent decades, the wetland park all over the world population is increasing rapidly. And domestic construction of wetland park, is the country, the government and the support of social from all walks of life thriving.Wetland park not only has the common park landscape features, also have a certain ecological characteristics and science popularization, it all depends on plant landscape construction. Plants as one of the main landscape elements, the wetland park can not only enrich the landscape, and can improve the ecological structure and biological community. Aquatic plants is an important type in wetland plant, has high ornamental characteristics, at the same time can adjust microclimate, purifying water quality and construct the harmonious community. So for the aquatic plants in the wetland in survey and configuration evaluation on the planning and development of wetlands is very necessary. In haizhu national wetland park as an example(hereinafter referred to as the haizhu wetland), the wetland in haizhu aquatic plant species,application frequency, phenophase, ornamental characteristics were investigated, and the research current situation of the aquatic plant configuration, provide theoretical reference for the further construction of haizhu wetlands. The main results were as follows:1, Since September 1, 2014 to March 2016, I am in haizhu wetland(including haizhu lake wetland, haizhu 1st and 2nd stage) in field investigation of aquatic plants,the results are as follows: haizhu wetland in the lakes, river and there are 78 species of aquatic plants in main channels, a total of 39 families, including floating plants has 3kinds, accounting for 3.8% of the total water plant in haizhu wetland; There are two kinds of submerged plant, accounted for 2.6% of total haizhu wetland aquatic plant;Four kinds of floating leaf plants, accounted for 5.1% of total haizhu wetland aquatic plant; Quite water plants, 42 species accounted for 53.8% of haizhu wetland aquatic plants within, the wet, 23 species accounted for 29.5% of haizhu wetland aquatic plant;Four kinds of freshwater mangrove plants, accounting for 5.2% of the haizhu wetland aquatic plants inside. With willow, bulrush, among them, water smartweed, such as alocasia 57 species of native plants, represented by foxtail algae, crassipes 21 foreign introduced species. Haizhu wetland aquatic plants, and most plant species, the most widely used, followed by wet plant. In all types of aquatic plants, gramineae, myrtle,araceae, apocynaceae plant species used at most, the most widely distributed, with reeds, iris, barracuda grass, aquatic canna, application of aquatic plants such as force again flower frequency can reach 60% or higher.2, Haizhu wetland aquatic plant phenological phase of the results showed that germination period mainly of aquatic plants in the wetland is in every year in March,April and October is coated, starting from April, wetland aquatic plants are in flower,in November, a large number of aquatic plant began to wither, rests primarily in December each year to the second year in February, but due to the unique climate in guangzhou, aquatic canna, crown grass and flowers and such plants are the four seasons flowers, not wither. In addition, the author also for aquatic plants in wetlands mainly design and color, plant height and is suitable for the depth of the water,provide the basis for reasonable configuration and application of aquatic plants.Survey, haizhu wetland aquatic plants is given priority to with flower type, design and color are red(aquatic canna, such as lotus, water lily), yellow(like water canna), blue(such as willow dish), purple(e.g., barracuda grass), white(such as egrets guan).Plant height range between 5 cm- 3000 cm, suitable for the depth of the water main is between 50 cm to 120 cm. According to these data, can be configured according to the colour collocation of aquatic plant community, can also judge that aquatic plants suitable for the growth of water environment, make its healthy growth, enhance ornamental.3, To haizhu lake, green heart lake, huaxi, pomegranate bay, groves wetland ten sights in aquatic plant landscape is analyzed. Mainly in haizhu lake lake waters,divided into inside and outside Chinese redbud, taxodium ascendens arbor with lotus flowers, and flowers and such a water plant, again complementary with brews, aimed at creating "green water show, and diving birds" lingnan water; The green heart lake is given priority to, the biggest characteristic is bitter grass making landscape of "underwater forest"; Huaxi carpet of flowers, evergreen plants and flower plants,mutual collocation, poem; Pomegranate bay coastal avenue system of aquatic plants,spring, summer, bauhinia, then spend considerable force, qiu dong with reedinflorescence, thriving; Groves wetland use of lingnan, the fruit characteristics of aquatic plants collocation, highlights the natural, ecological and open interest. Overall,the wetland in application of aquatic plant species richness, with lingnan culture characteristics, highlight the theme of landscape. In the collocation of colour diversity,integrity is strong, and the surrounding environment is tie-in and reasonable. However,haizhu wetland aquatic plant application also has shortcomings. As part of the attraction less trees application, ecological system imbalance. Are concentrated in the configuration, the commonly used, the early spring landscape depression, not enough crazy breeding and maintenance management of alien species, etc. These problems directly cause the quality of aquatic plant landscape.4, Aiming at the existing problem of haizhu wetland aquatic plant application,put forward the improvement proposal and configuration optimization model. The choice of aquatic plants to give priority to with native plants, when the choice, should consider to functional and view and admire a gender, improve the ecological benefits of aquatic plants, such as raw hygrophilous arbor + wet by, was submerged plant +water plants, submerged plant + + a floating leaf plants water plants, etc., in addition to this, also need to increase the intensity of maintenance and management of wetland plant, strive to build a harmonious, ecological wetland park landscape.
