| 摘 要： | 采用东北林业大学帽儿山实验林场1990年和2004年的固定样地调查数据及一元生物量预估模型,计算得到林场内各样地单位面积生物量,并运用地理信息系统的插值法得到整个研究地区的森林生物量分布图。在此基础上,分析了研究地区生物量的动态变化趋势及生物量与地形因子之间的关系。结果表明,经过10多年的经营,该地区的生物量呈增加趋势,生物量与海拔和坡度呈显著的相关性。通过回归分析,得到生物量与海拔高度的回归方程,并通过了统计检验。

| Abstract: | The biomass of each sample plot in Maoershan Forest Farm in Shangzhi City,Heilongjiang Province was calculated according to forest inventory data of 1990 and 2004 and biomass estimation models.Then a spatial distribution map of forest biomass was got by the interpolation method in GIS.The dynamic change of biomass in the study area and the relationship between biomass and topographical factors were analyzed.Results showed that biomass in Maoershan Forest Farm gradually increased after more than 10 years of ... |
