森林立地生产力评价指标与方法

A Review of Forest Site Productivity Evaluation Indicators and Methods

对国内外森林立地生产力评价指标和方法的现状、问题及发展趋势进行了综述。森林立地生产力评价指标可归纳为4类:林分高、林分的蓄积或者断面积生长量、林分特征和立地属性,基于4类评价指标产生了多种评价方法,不同方法各有利弊,其中,以立地指数评价最为常用。最后讨论了立地生长潜力评价方法、天然混交林立地生长潜力评价、区域性立地生长潜力评价研究及空间制图技术研究的发展。

In this study, the current situations, existing problems and development trends of the evaluation indexes and methods for forest site productivity both at home and abroad were reviewed. Forest site productivity evaluation index can be classified into four categories, including stand height,stand volume or basal area growth, stand characteristics and site attributes. On the basis of the above four evaluation indexes, a variety of evaluation methods are generated, and each method has its advantages and disadvantages, of which the method of site index evaluation is the most popular one. Finally, the evaluation method for site growth potential, site growth potential evaluation of natural mixed forest, the study of regional site growth potential evaluation and space mapping technique are all discussed.
