为了精细管理森林资源,需要简便易行、准确可靠的估测生境质量的方法,本研究的目的是根据树高(H)与相应的胸高直径(D)检验估测生境质量的方法.森林生产力是单位时间(年)的材积生产量.是预报资源管理所必须的数据,森林生产力的估测取决于生境类型和时间.与时间无关的生境质量可不考虑林龄进行无偏估计.以往用的生境指数法,把年龄对应的树高值作为生境指数(SI). In order to finely manage forest resources, an easy and accurate method for estimating the quality of the habitat is needed. The purpose of this study is to evaluate the method of estimating the habitat quality based on the tree height (H) and the corresponding breast height diameter (D) Is the volume of production per unit of time (year), which is necessary to forecast resource management, and forest productivity depends on the type and time of habitat, and time-independent quality of habitat can be unbiased regardless of age. The Habitat Index method uses the age-dependent tree height value as the habitat index (SI).
