Investigation And Application Study Of Aquatic Plants In Ganzhou City

Ganzhou has excellent natural conditions,and a long farming history.Since ancient times,Ganzhou has all kind of aquatic plants and various green vegetation.It is investigated that the existing aquatic plants in Ganzhou includes 28 families,46 species.Among them,the water plants accounts for the most,which is up to 60.8%.The main results,are as following:1.It is found through the survey that nearly two thirds of the aquatic plants in Ganzhou city were naturally distributed while the cultivated ones are less than one third of them.Garden common species especially the lotus and water lily,are still applied for the Large area application,and they are all planted in the surveyed park.However,colocasia antiquorum,horsetail and other indigenous plant have not been widely planted.2.The main emerged plants in Ganzhou exist in the form of emerged plant community,such as reed community,wild rice community,rush community and so on.The area of floating-leaved macrophyte and floating plants community are relatively small,and the distribution area reached the maximum in July and August,the growing season.There are also many submerged macrophyte community,such as Hydrilla community,wild celery community,Potamogeton malaianus community,hornwort community,and so on.The ecological benefit of the submerged plant community is greater than landscape benefits.3.Taking Ganzhou central ecological park as an example,the questionnaire survey method is used to set different words to investigate tourists around the aquatic plant landscape.It is found through the investigation that pure natural elements,water elements,waterscape plant landscape elements were mentioned 136 times.The proportion of these three elements is 15.65%,12.78%and 15.01%respectively,which showed that good waterscape effect can bring tourists the most visual experience.4.Through the evaluation of the ten kinds of garden environment elements,the overall satisfaction of waterscape management is only 0.44.It mainly reflected in two aspects.One is the lack of management of aquatic plants which leads to disorderly growth;the second is that due to the seasonal alternation,resulting in water surface pollution and the bleak winter plant landscape along the coast.5.After data processing and analysis,this paper puts forward that Ganzhou city should make the local tree species dominant in the process of application of aquatic plant,enrich the application of aquatic plants on the basis of increasing the species of evergreen aquatic plants,improve the management level to strengthen the winter water landscape construction,maintain the stability of aquatic plant landscape.
