Site quality estimation for Natural Korean pine forest using total height and diameter of dominant tree

用优势树全高和胸径的关系评价红松林的立地质量

The result was: Cavity entrance vertical diameter, Basic areas of 5-radius circle of tree species and slope of nests species was importanted nest-site selection.

结果表明，斑啄木鸟巢位选择的主要因子是5m范围内树的基面积、巢树位置坡度和洞口纵径。

The relative factors are discussed: maximum allowable pressure inside the site, permeating coefficient of of MSW, bio-gas production rate, diameter of the well, etc.

同时讨论了影响控制范围的各主要因素：垃圾层中最大允许压力、垃圾层的透气性能、垃圾的产气速率等。

The origin point, insertion site, length, transverse diameter of the branches of musculocutaneous nerve to biceps brachii were also checked.

测量肌皮神经肱二头肌支的起点、入肌点、长度、横径；

At different thinning intensity, the tree number (%) and volume (%) of big diameter woods increased with stand age; the growth rate increased with site index and thinning intensity.

不同间伐水平中、大径材的株数（%）和材积（%），随着林龄的增加而递增；立地指数级越高，间伐强度越大，递增的速度越快。
