| 摘 要： | 本文采用生长锥样木法研究了关帝山Ⅰ地位级华北落叶松林和管涔山Ⅱ地位级云杉林材积生长过程,分析确定了上述两类森林的数量成熟龄和成熟龄区间.研究表明,山西的云杉和华北落叶松林大部分未达到数量成熟.为了使目前实行的经营采伐技术更具合理性,分别林场在基层生产单位按林分类型分析和确定森林成熟很有必要.并提出生长锥样木法是解决这一问题的一种简捷、方便、灵活且能保证结果可靠性的方法,技术难度也小,便于基层应用.

| Abstract: | By imcrement-bar samplling system (ISS), the stumpage growth process of Larix Principis-rup-prechtii natural forest of site class Ⅰ in Gyandi Mountains and Picea spp. (includes P. meyeri and P. wilsonl) natural forest of site class Ⅱ in Guancen Mountains are studied in this paper. The quantitative maturities and the matural ranges of two types of forest are analysed and determined. It is proved also in this paper that most of the two forest types in theregions mentioned above have not been in quatitative matural ages. For efficient memagement and utilization of the forest resource later in Shanxi, it is necessary to determine the matural sges for all important typortant types of forest in every forest farm. This paper proposes that the ISS is a simple, eonvenient and reliable method to solve the problem, especially suitable for basic units to deal with different scaled objects. |
