Tree mortality and CWD input rates change greatly with the stands in space and time.②The number of five-decay classes CWD with different decay, CWD covered area, CWD volumes and biomass is normally distributed.③The structure of CWD diameter class is not correlated with living tree, and the falling orientation of CWD with prevailing wind is also not correlated.④The decay formulae of Pinus koraiensis and Tilia amurensis are Y〓=0.3747e〓 and Y〓=0.4454e〓 respectively. Their decay rate constant intervals are 0.0162-0.0230/a and 0.0274-0.0390/a respectively, and their fragmentation rate constants are 0.0068a〓 and 0.0115a〓 respectively.⑤The average time spans for Pinus koraiensis and Tilia amurensis CWD to lose their 50％ weight take 43 years and 25 years respectively, and the average time spans for Pinus koraiensis and Tilia amurensis CWD to lose their 95％ weight take 185 years and 106 years respectively. CWD diameter has no influence to decay rate constant of Pinus koraiensis. The bottom of CWD decays more rapidly than the top and the sides of CWD. The decay rate constant decreases gradually from sapwood to heartwood.⑥ CWD is an important nutrient pool in Korean Pine mixed forest ecosystem. In CWD nutrient pool, the contents of C, N, P, Ca, Mg, K, Na are respectively 3361.12kg/hm〓, 26.83kg/hm〓, 3.68kg/hm〓, 33.33kg/hm〓, 2.67kg/hm〓, 4.73kg/hm〓, and 1.42kg/hm〓. In the decomposition processes of CWD, the content of carbon is stable, the ones of N, Ca and Mg are increasing, the content of K is declining, and the contents of P and Na are random.
主要研究结果如下：①风干扰是倒木形成的主要原因，林木年死亡量和倒木输入量随着林分时空变化差异较大，林木年死亡量为0.15～0.66t/hm〓，倒木年输入量为0.03～0.19t/hm〓，倒木的数量为82株/hm〓，站杆8株/hm〓，倒木的生物量为7.90t/hm〓，其中，红松和紫椴是倒木形成的主要树种，占总生物量的59.17％，倒木的覆盖度为1.31％；②不同腐烂程度倒木株数、倒木覆盖面积、倒木体积和倒木生物量呈正态分布格局；③倒木的径级结构与活立木径级结构不相关，倒木的方向与主风向不相关；④红松倒木和紫椴倒木的分解模型分别为Y〓=0.3747e〓，Y〓=0.4454e〓，单项指数衰减模型是红松倒木和紫椴倒木分解较为理想的数学模型，其年分解常数区间分别为0.0162～0.0230和0.0275～0.0390，年粉碎常数分别为0.0068和0.0115；⑤红松倒木和紫椴倒木分别在43a和25a时重量损失50％，95％分解年限分别为185a与106a，胸径大小对分解常数无显著影响，倒木下方比倒木上方和侧方分解速率大，倒木边材到心材的不同层次，其分解常数逐渐下降；⑥倒木是重要的养分库，在红松阔叶混交林生态系统中，倒木库含C量为3361.12kg/bm〓、含N量为26.83kg/bm〓、含P量为3.68kg/bm〓，含Ca量为33.33kg/hm〓，含Mg量为2.67kg/hm〓，含K量为4.73kg/hm〓，含Na量为1.42kg/hm〓。
Six classes of diameter were determined as 2, 4, 6, 8, 10, and 12 depending on the range of DBH (0-3, 3-5, 5-7, 7-9, 9-11, and 11-13 cm). The results showed that: 1 After 5-year closed treatment, the population quantities Q. mongolica, Tilia mandshurica and Ulmsis laciniata decreased with the increase in diameter class, which indicated they were healthy populations; 2 After 16- year closed treatment the tree number of Tilia mandshurica and Ulmsis laciniata decreased because of canopy coverage increasing and became the associated species in Q. mongolica population; 3 Q.
结果表明：在封育5年样地内，蒙古栎、糠椴和黄榆种群的数量均随着径级的增加而单调下降，表明均为增长型种群；在封育16年以后，由于林内乔木层的盖度较大，糠椴和黄榆种群均呈不同程度的衰退，已经成为蒙古栎种群的伴生种群；封育24年样地中，蒙古栎种群明显成为优势树种。
