摘要
以湖北省森林蓄积量动态监测现状体系为基础,介绍森林蓄积量动态监测方法、成果出数测算相关算法,通过典型样地模拟测算,比较不同测算方法的差异,探讨蓄积量监测出数测算存在的问题,客观分析测算优势与不足,以静态指标和动态测算指标结合、联合森林资源自然增长率为基础的测算方法,兼顾森林资源消耗和减损量,测算成果数据偏差小、误差低、具有精确性、精度高,两者互补,可为森林蓄积量年度动态监测成果数据测算提供参考。
Based on current status system of dynamic monitoring of forest stock volume in Hubei Province,this paper introduced methods of dynamic monitoring of forest stock volume and the relevant algorithm formulas for calculation of results.Through the simulation and calculation of typical plots,the differences of different measurement methods were compared,and problems existing in the calculation and calculation of forest stock monitoring are discussed.The advantages and disadvantages were objectively analyzed,combination of static indicators and dynamic indicators,combined with the natural growth rate of forest resources,taken into account the consumption and loss of forest resources,and had small deviation,low error,accuracy and high precision,which are complementary to each other,and could provide a reference for the annual dynamic monitoring of forest stock.
