The results are as follows:The relationship between the precipitation and the stemflow is a linear regression. The stemflow of six forest types is Broadleaf forest, Conifer and broadleaf forest, Cupressus funebris forest, Mixed conifer forest, Pinus massoniana forest and Shrubbery and grass land in order.

结果如下：树干茎流量与降雨量成线性相关，回归方程达到极显著水平；6种森林类型的树干茎流量从大到小依次为阔叶林、针阔混交林、柏木林、针叶混交林、马尾松林和灌草地；不同树种间的树干茎流量差异极显著，影响树干茎流量的主要树体特征因子是冠型结构、胸径和平均冠幅。

The throughfall of six forest types is Shrubbery and grass land, Pinus massoniana forest, Cupressus funebris forest, Conifer and broadleaf forest, Broadleaf forest and Mixed conifer forest in order.The relationship between precipitation and the canopy interception is a power regression.

降雨初期，林冠截留量随着降雨量的增大而增大，但随着林冠吸水饱和，林冠截留量会逐渐趋于一个稳定范围。6种森林类型的林冠截留量从大到小依次为针叶混交林、马尾松林、柏木林、针阔混交林、阔叶林和灌草地。

The results showed that: The lignin riddance processing with microwave auxiliary was very quick and efficient. And the effect to the hardwood Fraxinus mandshurica samples is better than that to the softwood Larix gmelini.

结果表明，微波辅助法在阔叶材水曲柳和针叶材落叶松的木素脱除方面表现出快速、高效，且对于水曲柳的效果好于落叶松。

Veneer of doors and glass doors used in Changbai Mountain baisong unique coniferous wood, Larch, the Korean pine and oak hardwood timber wood, raw materials for processing from Ash.

贴面复合门和玻璃门采用长白山特有的针叶材白松、落叶松、红松和阔叶材柞木、水曲柳为原料加工而成。

After four months of observation of the growth season, the author reveals in the thesis the day- and month-dynamic characteristics of the net photosynthetic rate of Dahurian Larches, which are of different ages, densities and stand classes. The author also compared the net photosynthetic rates of the leaves on different-age braches and with the crowns of different layers and directions. In addition, the author analyzed the effects of some ecological factors on net photosynthetic rate as well.

通过生长季节四个月的定株观测，揭示兴安落叶松的光合特征，即不同年龄、密度、分级木净光合速率的日动态和月动态特征，比较树冠不同层次、不同方向和不同枝龄上针叶的净光合速率的日动态和月动态特征，分析光照强度、温度、CO2浓度等生态因子对兴安落叶松净光合速率的影响。

Sables tended to select old-growth coniferous forests, and they specially selected small tree's density, big tree's density, big tree's DBH and Log's density sables preferred milddle cover's site to open sites and high cover's sites. Habitat Selection varied with season. In winter.

紫貂喜好原始针叶林，对小树密度，大树密度、大树DBH和倒木密度有很强选择性，紫貂喜好中盖度林地而避免开阔地和高盖度林地，一年四季其生境选择有一定的差异。

The wood properties of alder is similar to that of poplar and birch which could be used to produce different kinds of pulp.The paper is a review about pulp production potential and status of pulping/paper-making and research on wood property of alder in the world.

桤木是一种商用种植较有发展前景的阔叶树种，生长迅速、固氮能力强，木材性质类似于杨木和桦木，可用来开发研制不同的浆种，与针叶木浆或其它阔叶木浆配抄可以生产高质量的印刷纸和书写纸等。

There are remarkable differences among different succession community of the fallen tree and snag in terms of their volume and decay degree and decay degree of the fallen. The distribution trend generally abides by the rule of increasing with the succession. The decay degree obeys normal distribution.

通过研究表明：长江上游暗针叶林生态系统的CWD总量是101.74 m3/hm2，它的组成体--倒木和站杆在不同演替阶段的容积和腐烂程度是明显不同的，随演替递进，程度加大，分布呈正态分布。
