摘要
简要介绍了草地地上生物量估测的不同方法及其各自特点,阐述了反射光谱特征参数、植被指数与草地地上生物量之间的关系,分析了草地类型、季相条件以及植被覆盖度对植被指数、草地地上生物量估产模型的影响。
In this paper, the characteristics of different methods for estimating pasture aboveground biomass were briefly narrated, and the relationship between the reflectance spectrum characteristic parameters, vegetation indices and pasture aboveground biomass were expounded. In addition, the influence of the grassland types, the season phase conditions and the vegetation coverage to the vegetation indices as well as the estimation model of the pasture aboveground biomass were analyzed.
