森林生物量研究的若干问题及完善途径

Some Problems and Perfect Approaches of Research on Forest Biomass

介绍了森林生物量研究的背景。侧重论述了森林样地生物量算法及其精度分析、森林生物量估计模型的精度分析、森林生物量监测的必要精度与不确定性、森林蓄积量与生物量的转换模型、大区域多树种生物量转换模型、利用广义3S技术建立森林生物量模型等理论、技术、方法问题。强调了森林生物量模型的稳健估计算法、模型的方差-协方差模型及其不确定度。

Development history, motive, significance and methods of research on forest biomass were explained. The methods of data processing and data analysis were presented. The study emphasized particularly on arithmetic and precision analysis of forest biomass in forest sample plots,precision analysis of estimated model and the necessary precision and determined nature of forest monitoring as well as the transformed model of forest biomass and forest stock volume. Also the paper paid especially attention to the research on the transformed model of many types of trees in big areas. By 3S technology in broad sense the theory, technology, method of the forest biomass model were found.The study stressed on the estimate arithmetic,variance-covariance models and the degree of uncertainty.
