The results show that the content of Do in runoff of Coniferous mixed forest is lowest and that of Betula costata is highest.

研究结果表明：樟落混交林地表径流的Do含量降的最低，而枫桦地表径流的Do含量最高，对Do的影响最小。

The validation for each species crown ratio model indicats that the precision of prognose are all exceed 91%,also pass the Ftest except Betula costata and Acer mono.

各个树种的冠长率模型的检验结果表明，10个树种的预估精度都超过了91%，除了枫桦和色木，都通过了置信椭圆F检验。

The results showed that: with the regression analysis of Betula platyphylla, Pinus koraiensis, Abies nephrolepis, Picea koyamai var koraiensis, and Betula costata, there was a significant negative correlation between neighborhood interference index and the growth (0.40~0.89) and the correlation extent depended on the neighborhood influence zone and slope. The neighborhood influence zone corresponding to maximal regression coefficient R~2 was the neighborhood influence radius. Based on the linear subsection regression between neighborhood interference index and influence zone of five species, the neighborhood interference index increased with the increasing zone and there was a previous increasing trend in a certain scope, while the increasing trend slackened beyond the zone. The neighborhood influence zone corresponding to transition point was the neighborhood influence radius. The neighborhood interference index positively correlated with the neighborhood influence zone and the range of R~2 was 0.40-0.64. With the analysis of tree cores of Juglans mandshurica, Fraxinus mandshurica at middle and lower slope in a plot which was fostered in 1995, the distance which the growth release farthest neighborhood and object stub was judged, thus the neighborhood interference radius was inferred. According to the studies, we found that the neighborhood interference radius was different among different trees, even if the neighborhood interference radius of the identical tree species also had the difference at different slopes.

结果表明：通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与生长量回归分析发现，邻体干扰指数与生长量呈显著负相关(0.40～0.89)，相关程度因邻体影响范围和坡位而异，R~2达到最大值所对应的影响范围即为邻体影响半径；通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与影响范围的线性分段拟合，邻体干扰指数随影响范围的增加而增加，其在一定的范围内上升较快，而超出该范围后上升的幅度变慢，变化的转折点所对应的影n向范围可以判定为邻体影响半径，线性回归显著(0.40～0.64)；通过对1995a抚育的胡桃楸、水曲柳样树进行研究，分析邻体树种的中坡位和下坡位的生长锥芯，判断产生生长释放的最远邻木与基株树桩所对应的距离，推断邻体影响半径；根据研究发现，邻体影响半径因树种不同有一定的差异，即使同一树种的邻体影响半径在不同坡位也有一定的差异。
