The simulated thermo-degradation of the two other samples, Cunninghamia lanceolata and Fraximus mandshurica, accorded well with the experimental result.

利用该模型对杉木和水曲柳的热失重行为进行模拟，得到了与试验结果较为吻合的计算结果。

According to stand biomass data of Cunninghamia lanceolata Hook measured in Minjiang watershed, based on the compatibility of models, the relations of each component were analyzed, and the stand biomass compatible models were established by using SPSS analysis software.

本研究根据闽江流域杉木林分的生物量实测数据，从模型相容性的定义出发，分析各分量的代数关系，利用SPSS统计分析软件构建了林分各分量的相容性模型。

The softwood of Cunninghamia lanceolata and Pinus massoniana were steam-treated at temperature 90℃ and 100℃. The hard wood of Nothofagus spp.

分别对针叶树材的杉木和马尾松木材，以及阔叶树材的假水青冈和香椿木材进行汽蒸处理。

The strands were made by planning slicing and pressure slicing with Cunninghamia lanceolata as material and their dimension and shape were analyzed.

以杉木 Cuninghamia lanceolata生材为原料，采用平刨法和压刨法制备长形刨花，并对刨花尺寸和形态进行分析。

The results showed that the human disturbance didn't change the dominant positions and roles of Pinus massoniana and Cunninghamia lanceolata in arbor. But it decreased the average diameter at breast height and average tree height and changed the species composition.

结果表明，人为干扰对乔木层马尾松Pinus massoniana和杉木Cunninghamia lanceolata优势种的主体地位和作用没有根本性的改变，但使群落平均胸径和平均树高降低，群落种类组成发生变化。

One of hot spot being forest hydrology research is canopy precipitation interception, and this paper is on the foundation of the existing research achievements of analysis home and abroad, and uses the forestry statistical analysis software of development by oneself to go on the analyses of data , and major research result indicates :(1) Schima superba canopy is more interception loss than Cunninghamia lanceolata canopy.

林冠截留是森林水文研究的热点之一，本文在分析国内外现有研究成果的基础上，运用自主开发的林业统计分析软件进行数据分析，主要研究结果表明：(1)木荷林冠截留量大于杉木林冠截留量。

Studies on the relationship of species showed that overall association of Cunninghamia lanceolata forest was significant positive correlation and the community was at a stable stage.In 22 species,7 species pairs exhibited highly significant positive or negative association.

种问关联性的分析表明，杉木林群落总体相关性表现出显著的正相关，反映了该群落的稳定性。22个树种，具有显著正联结或负联结的种对有7对。
