一.前言在森林經理工作中,正确地判定森林生長的环境条件,对于組織合理的經营措施有着重大的意义。而評定森林生長条件的优劣,一般是根据测樹指标——地位級進行的。因为它是土壤、气候等森林立地条件与林木本身生物学特性綜合表現的森林生產力的指标。至于查定地位級的方法,普通是依林齡和林分高,根据既有的地位級表确定的。因此,所用的地位級表適合于該地区的程度,就决定着森林調查結果的精确性。在我國目前虽然还沒有研究和調制出適合于全國和各地区的地位级表,但在党和政府的正确领导下,随着我國森林經理工作的蓬勃發展,調制地位級表和調制其他森林
I. Foreword In the work of forest managers, to correctly determine the environmental conditions for the growth of forests is of great significance to the organization of rational management measures. The assessment of the merits of forest growth conditions, generally based on the measurement of tree indicators - status level. Because it is soil, climate and other forest site conditions and the overall biological characteristics of the forest itself, an indicator of forest productivity. As for the method of ascertaining the status class, the average age and forest stand height are determined according to the existing status class table. Therefore, the degree to which the status rank used is appropriate for the area, which determines the accuracy of the forest findings. In our country, at present, although we have not studied and formulated a status-level table suitable for the whole country and various regions, under the correct leadership of the party and the government, as the work of forest managers in our country thrives, the status-level list and the modulation of other forests
