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.
In this paper, the growing cone-like wood method was used to study the volumetric growth of Picea crassifolia and Guanziyashan Ⅱ spruce forest in Guandi Mountain, and the quantitative maturation and maturity ages of these two forest types were analyzed. , Most of the spruce and north Larix principis-rupprechtii in Shanxi did not reach the maturity level.In order to make the current operation of harvesting technology more reasonable, respectively, in the grass-roots units of production units in the forest type analysis and to determine the maturity of the forest is necessary and proposed growth Cone-like wood method is a simple, convenient, flexible and can guarantee the reliability of the method to solve this problem, the technical difficulty is also small, easy to grass-roots applications.
