黑龙江省东部山区森林生物量的时空变化分析

Temporal and Spatial Analysis ofForest Biomass at Eastern Mountain inHeilongjiang Province

掌握森林生物量的时间变化特征和空间分布,有意于碳达峰、碳中和目标的实现,以及应对气候变化具有重要意义。本文分析了2013年至2021年黑龙江省东部山区森林生物量及其地形因子之间的关系。结果表明,研究区森林生物量多年均值为9.58 t,生物量增加区域要多于减少区域;高程在400 m左右的森林生物量占比最多,缓坡和北坡的生物量占比较高。

The spatial distribution of forest biomass and its changes are important for achieving the carbon peak and neutrality targets and coping with climate change.Analyzing the variation characteristics of forest biomassin Eastern Mountain of Heilongjiang Province from 2013 to 2021 and the relationship between biomass and topographic factors.The results show that the multi-year average value of forest biomass in the study area is 9.58 tons,with more biomass increasing than decreasing areas;the forest biomass accounts for the largest proportion of forest biomass at an elevation of about 400 m,and the biomass accounts for a higher proportion on gentle slopes and northern slopes.
