地位级是反映一定树种的立地条件的好坏和林分生产力的指标。地位级的优劣是以一定年龄的林分的平均树高的差异划分的,这种划分方法主要应用于树种单纯的同龄林。在森林经营工作中,对于立地条件的调查以及地位级的划分具有十分重要的意义,因为只有对森林生长的立地质量有一个清楚的了解,才有可能采取一定的营林措施改善立地条件,提高林分的生产力;同时,由于生长在不同立地上的林 The status level is an index that reflects the quality of site conditions and the stand productivity of certain tree species. The advantages and disadvantages of the status level is based on the difference of the average tree height of the stands of a certain age, which is mainly applied to the simple same-age forest of the tree species. In the forest management work, the investigation on site conditions and the division of status levels are of great significance because only when there is a clear understanding of the site quality of forest growth, it is possible to adopt some measures to improve the site conditions and improve the site conditions Stand productivity; the same time, due to growth in different sites on the forest
