成都市中心城区城市森林树木的数量结构特征
Study on quantitative structure characteristics of forest in central of Chengdu City
摘要
Abstract
By using the method of remote sensing image interpretation and field investigation, this paper quantitatively analyzed the quantitative structure and greening structure of forest in the central of Chengdu City, the results showed that: there were 118 species of tree species in the central urban area, belonging to 40 families and 62 genera;the number of shrub and evergreen trees accounted for 3.71％and 53.48％ respectively;22 species of trees with the ratio of more than 1％and 11 species of tree with an important value more than 0.003.The cumulative important value of top 11 species achieved 0.685, among them, it showed that Cinnamomum camphora(0.119), Cinnamomum japonicum(0.087), Robinia pseudoacacia(0.085), Salix babylonica(0.082), Ficus benguetensis(0.064), Metasequoia glyptostroboides(0.057), Ligustrum lucidum(0.048), Koelreuteria paniculata(0.041), Ginkgo biloba(0.039), Camptotheca acuminate(0.032) and Populus(0.031).The number of trees and species in the tree height (5 m≤H<10 m) and DBH (10 cm≤DBH<30 cm) was the largest, but decreased with the increase of crown cover area and tridimensional green volume.The trees with tree height below 15 m or DBH smaller 30 cm accounted for 91.38％and 88.74％respectively.The tree species with tree canopy cover area under 50 m2 of tridimensional green volume less than 100 m3 took a part of 86.93％and 70.49％respectively.The result indicates that the greening tree species in the central urban area of Chengdu not only have great development potential in the form of height and DBH, but also have a large growth space on the green quantity.关键词
