| Color-leafed tree species is a kind of garden plant that is worth vigorously promoting and has expansive application prospect in riverfront landscape planting.In order to better know about the application of colored-leafed trees in Shijiazhuang riverfront landscape,this thesis takes the riverfront landscape in Shijiazhuang city as the investigation region and selects eight typical sampling regions to conduct field survey on the category and application conditions of colored-leafed trees in garden plant landscape and proposes reasonable suggestions according to the analysis of existing problems in riverfront landscape.As proved by the investigation results,riverfront landscape revetment in Shijiazhuang city mainly includes rigid revetment,prefab revetment and natural ecology revetment.There are 35 families and 105 species of colored-leafed trees,including arbor,bush and vine plants.Shijiazhuang riverfront landscape has relatively rich colored-leafed trees and high diversity of plant community.According to the investigation and data analysis,this thesis screens 13 red-leaf arbor,4 yellow-leaf arbor,4 red-leaf bush,4 yellow-leaf bush and 4 colored-leafed pants proper for northern riverfront landscape.Based on comprehensive analysis results,this thesis summarizes regular matching plants for colored-leafed arbor,colored-leafed bush and colored grass in combination with different growth habits of trees.This study observes that in northern riverfront landscape of Shijiazhuang city,the application of colored-leafed trees exists problems in species variety,conformity with ecological habits and imperfect conservation management and this naturally influences the exertion of colored-leafed tree landscape functions.Targeted at above-mentioned problems,this thesis proposes the countermeasures to enhance colored-leafed tree introduction and promotion,colored-leafed tree species configuration optimization and conservation management. |
