The Study On The Ground Cover In Plank-Buttress Area Of Greenbelt In Guangzhou City

A large number of Plank-Buttress trees have planted in greenbelt in Guangzhou.Their roots are usually distributing over the base of the trunk.In the Plank-Buttress area,the ground cover have grown unhealthy and unevenly.Some times it has lacked of plants.It will have adverse effect on the scenic of the plant community.Considering this,I expect to find the solution by the research,and improve the the scenic of the plant community.This study is to explore the root zone of Guangzhou park green land to be plant construction methods.On the previous in roots and by the relevant research and plant by plant ecology theory as the foundation,through the roots of trees and in the root zone in 6 in Guangzhou park green space plant species,were fixed on the 399 plants to be designed by the test sample,the survival of plants and the combination of landscape aesthetics,etc,are to be plants in the root zone plate construction method.The main conclusions are as follows:(1)Through investigation,it is found that the concentration of Moraceae(43.17%)and Myrtaceae(13.17%)in 23 sections and 40 kinds of 410 Plank-Buttress trees.Plank-Buttress area of the board to show the root of the tree root phenomenon,both the root of the tree with the root of the biological characteristics of the innate factors,but also the tree does not have a board root but the adverse site conditions affect the formation of the acquired factors.It's a total of 20 plant species of 33 families,of which the Schefflera odorata cv.variegata and Hymenocallis littoralis is most commonly used,the frequency is 9.76%.The two most commonly used plants are plants that are negative for the use of green space in Guangzhou park.In addition to the three leaves of Wedelia trilobata of the 32 species of ground cover plants have strong shade tolerant ability.(2)The results showed that the cover effect of ground cover was closely related to the biological characteristics of the leaf type level and the reproductive mode of the plant.19 or more qualified(Alpinia zerumbet & Monstera deliciosa etc.)for the coverage effect there are 10 kinds of plant leaves large or giant leaf groundcover plants,covering 5 kinds of plant good results or above are large or giant leaf plants,large leaves or giant leaf vegetation cover better;survey of 6 herbaceous vines(Zebrina pendula & Piper sarmentosum etc.)only 1 kinds of coverage is not qualified,and herbaceous vines have stolons of groundcover plants in better coverage effect;not s toloniferous banded leaf plants are needed to achieve better results by planting coverage.(3)Ecological factors in Plank-Buttress area of the plate has the characteristics of weak light intensity,short time and high humidity,so the variety of the plat e and the ground cover plants should be selected according to the principle of "suitable tree".At the same time to demand attention by plants and differences in the Plank-Buttress trees to ecological factors can not be too large,avoid care for this and lose that.(4)The landscape pattern of the root tree is related to the configuration of the root zone,where the flat tree pool and the high tree pool and the solitary tree and the group planting tree and the performance of the root of scene,The need for the analysis of the role of the landscape tree in the landscape,so that the plants are subject to their needs.(5)In Plank-Buttress area by the landscape aesthetic connotation of plant configuration is an important manifestation of Guangzhou "Flower C ity" reputation of Guangzhou,there are 12 color leafed plants,the frequency is 44.61%;there are 9 kinds of ornamental plants(Ruellia elegans?Neomarica gracilis etc.),the frequency is 28.82%.,which need to do right by the appearance and quality plant co lor,volume,to focus on the construction work.In addition,the research even refer to moss and epiphytes growing,e ngineering measures and abiotic covering's used in Plank-Buttress area.
