本文以森林Gap模型的理论为基础，通过大量的外业调查，建立了长白山阔叶红松林的ZELIG模型，并根据ZELIG模型的模拟结果对长白山阔叶红松林带的树木生长的环境因子进行了评价，同时对阔叶红松林带内的几种主要的森林类型进行了动态模拟，最后运用ZELIG模拟了阔叶红松林的择伐试验。

The compatibility of both Gvirens and B.firmus was researched. The fermentation filtrate of Gvirens , under the concentration of 70%, had not distinct inhibitory activity to B.firmus, the biomass of B.firmus would decrease with above the 70% filtrate of Gvirens, but the fermentation filtrate of B.firmus had not inhibitive role to Gvirens. 7, The cooperation control of both Gvirens and B.firm to the pine needle blight was explored:(1) Pathogen inoculation happened prior to the bio-control treatment for 7 days, however, the disease index and control effect had not distinct differences in any treatments even if combination of the two antagonists, but the susceptibility for different kind of pine were different.(2)when antagonist and pathogen were inoculated at the same time, some control effect to the pine needle blight, including certain extent cooperation control of both Gvirens and B.firm were proved, but it wasn't distinct when two antagonists used separately, and the change of the antagonist concentration had little effect to the control effect.

G.virens与B.firmus对松赤枯病的协同控制显示：(1)预先接种病菌后(7天)再进行生物防治处理，不管那种情况，感病指数和防治效果在处理间差异不明显，浓度影响无显著差异，即使是两种生防制剂联合作用也未显著提高其防效，但不同树种间的感病性有明显差异；(2)领抗菌与病原菌同时接种，对松赤枯病有一定防治效果，两菌联合有一定的协同作用，两菌分别单独施用防效差异不显著，浓度变化对防效影响不大；(3)预先接种颇抗菌能显著提高防治效果，两菌联合处理防效更优，感病树种的感病指数可降至13一15，抗病树种的感病指数可控制在3%左右；在同一浓度下B.f1'r功US、叹叮厂即s间无显著差异，在同一领抗菌下，浓度愈高，防效愈高：松，(4)三种生防接种方式的平均效果分析表明，叹F行ens最高平均防效49.5%黑 B。

Pine wilt disease is present and the future period of the greatest threats to forest biological disasters, pine to death from the illness is usually just two months later, 3 to 5 years can be destroyed into pieces pine forest.

松材线虫病是当前及今后一个时期威胁森林最大的生物灾害，松树从染病到死亡通常只需两个月左右的时间，3~5年即可摧毁成片松林。

Pine wilt disease is one of the most important pine tree diseases, and its causal agent is Bursaphelenchus xylophilus, which is a great threat to the pine forestry in many countries such as China Japan, Korea, the US, Canada, Mexico, and Nigeria, etc. It is one of the most important quarantine organisms, and also listed on A2 in China, which lead to imponderable loss every year.
