森林多种效益的计量是一个重要的理论问题,也是一个复杂的技术问题。在国外,二十余年来仅原苏联、美国、日本、德国瑞典等作过研究,而在我国则属起步阶段,至今尚缺乏成型的理论和方法。特别是林业从以生产木材为主向以发挥生态效益为主转变之后,更应有一套科学的评价体系。本文以某林区为对象,从测树学角度,结合森林生态经济学、森林水文原理,森林经理学探讨适合于该林区特点的多种效益计量指标和计量方法,并提出能综合考虑多种因子的一般性预估模型。为探讨森林生态效益和集约经营提供依据。
Measurement of forest benefits is an important theoretical issue, but also a complex technical issue. In foreign countries, only the Soviet Union, the United States, Japan, Germany and Sweden have been studied in more than 20 years, but in our country it is an initial stage. So far, there is still a lack of theories and methods for shaping it. In particular, forestry from the production of wood-based to give play to the ecological benefits of the main change, there should be a set of scientific evaluation system. In this paper, a forest area as the object, from the perspective of tree measurement, combined with forest ecological economics, forest hydrology principles, forest management theory to explore the characteristics of the forest suitable for a variety of indicators of measurement and measurement of efficiency, A general estimation model of species factors. It provides the basis for discussing forest ecological benefits and intensive management.
