摘要/Abstract

摘要： 作者根据巴叶斯的判别理论,用与林分立地类型密切相关的林分因子,建立判别函数式。在实际工作中可先凭经验判定林分立地类型,再通过判别函数或计算的方法,两者紧密结合,就可准确无误地确定林分立地类型,为拟定营林措施提供理论根据。

Abstract: The site type of a stand is the material basis for the growth of forest crop. In forestry practice establishing the site type of a stand exclusively by professional knowledge and practical experience may sometimes fall into fallacy, resulting in inadequate forest operations, hence economic loss.Based on the theory of Bayes and using factors closely related to site types of stands, the author developed a functional formula for site type identification. In practice, through tentative determination of the site type of a stand by experience supported by calculation with the identification formula, it is possible to secure a very precise assessment of the site type, thus providing a theoretical basis for adopting desirable silvicultural measures.
