摘要
依据卫星影像资料,利用单木生物量方程计算方法,对沈阳城市公园绿地乔木层生物量进行计算,就树高、胸高断面积等影响因子与市区4种城市公园绿地类型生物量的关系进行分析比较。结果表明:各类型城市公园绿地单位面积的生物量均随变量等级的提高而呈现增大趋势,单位面积平均生物量总体呈现出先期增长缓慢而后期增长迅速的特点。
Based on the satellite image data, the biomass in unit area of ShenYang urban green space was calculated by using single-tree biomass equation. The effects of tree height and basal area of breast-height on the biomasses of four kinds of urban parks green spaces were compared and analyzed. The results show that urban green space biomass in unit area increases with the increase of tree height and the breast-height basal area. The average biomass in unit area increases slowly at the beginning and fast at the late stage.
