摘要:
 借助QuickBird卫星影像和抽样调查,就郁闭度、树高、冠幅和胸高断面积等指标对沈阳市区4种功能的城市森林三维绿量的关系进行了量化分析。结果表明:各类型单位面积城市森林的三维绿量均随影响因子等级的增大而呈现逐步增大的趋势,随郁闭度、树高、冠幅和胸高断面积相邻等级的平均增长幅度分别为267.02%、75.24%、65.91%和46.06%。单位面积各类型城市森林在相同因子等级下其三维绿量总体表现为道路林和附属林较低,生态公益林和风景游憩林较高的特征。影响城市森林三维绿量的关键影响因子呈现阶段性特征,低三维绿量阶段关键影响因子为郁闭度,而在高三维绿量阶段则是郁闭度和胸高断面积。
Abstract:
 To explore the quantitative differences of urban forest of different types and various influencing factors,the three-dimensional green biomasses (TGB) of four functional types of urban forest in Shenyang were analyzed based on QuickBird satellite images and by using sampling survey.The results showed that the TGB per unit area of urban forest of various types increased gradually with the increase of the influencing factor grade.The average growth rate of TGB and that of the adjacent grade of canopy density,tree height,canopy diameter and basal area at breast height was 267.02%,75.24%,65.91%,and 46.06%,respectively.The overall TGB of road forest and affiliated forest was lower and those of ecological and public welfare forests and landscape and recreational forests were higher at the same influencing factor grade.The key influencing factor of the three-dimensional green biomass of urban forest indicated the stage characteristics.The key influencing factor in the lower stage of TGB was canopy density and those of higher stage were canopy density and basal area at breast height.
