使用“油松林疏伐试用标准”进行油松林疏伐前的施工设计,由于只需要每亩株数、每亩蓄积和林分平均直径等三项主要因子就能进行设计,因此,利用六株样园的调查方法即可满足设计要求。和习惯调查设计方法相比,省工、省时,而且调查方法简单,使用方便。根据“试用标准”提出的设计要求,也比较符合林木生长的客观实际,使疏伐起到了改善林况,促进林木生长的作用。
Using “Trial Standard for Thinning of Pinus tabulaeformis” to design the pre-thinning of the pine forest, only three major factors such as the number of trees per mu, the accumulation of per acre and the average diameter of the forest can be designed. Therefore, Park survey methods to meet the design requirements. And habitual survey design methods, labor-saving, time-saving, and the survey method is simple and easy to use. According to the “trial standards” proposed design requirements, but also more in line with the objective reality of forest growth, so that thinning played a role in improving forest conditions and promoting forest growth.
