    Review of methods on estimating forest above ground biomass

    • 摘要: 根据所采用数据源的不同,介绍了当前国内外森林地上生物量测算中所用的主要方法,即基于森林资源清查的方法和基于遥感估测的方法。根据国内外前期研究成果,概括了这两种方法的特点及其存在的一些不足,初步探讨了结合多源数据联合估测森林地上生物量的方法。结合当前森林地上生物量研究中存在的问题,讨论了估测方法的尺度、模型与参数化以及精度与验证的问题,最后提出了今后森林地上生物量研究中应重点开展的工作。

       

      Abstract: According to the data source used, the major methods globally used to estimate forest above-ground biomass were introduced in this paper. The methods can be categorized into forest inventory data based method and remote sensing based method. Based on previous studies conducted in China and abroad, we summarized the characteristics and the deficiencies of these two kinds of methods and then preliminarily explored the synergetic method in estimating forest aboveground biomass using multi-source data. In accordance with the deficiencies of estimation methods, some discussions about the scale, parameterization and validation of the models were given and some work concerning the estimation of forest aboveground biomass in the future was stressed.
