我国东北部山地温带针阔叶混交林是以红松阔叶林为主体,以红松(Pinus koraiensis)为优势,与多种阔叶树混交,构成原生的地带性顶极群落。最近二十年来,由于大量采伐,原始红松林的面积日益减少,目前剩下的已经不多了。加之红松林天然更新十分困难,人工更新又很缓慢,这样下去红松林有绝灭的危险。为了使红松林迅速发展,目前存在不少急待解决的问题,虫害问题即是其中之一。为此,我们从1974年开始,对红松林害虫进行了一系列的调查研究。首先,我们在红松人工林内调查了红松幼树分叉与虫害的关系,接着,我们研究了采伐迹地上为害红松幼树的球蚜,与此同时,我们以黑龙江省生态学会的名义组织力量对小兴安岭林区带岭和五营两个自然
The temperate coniferous and broad-leaved mixed forest in northeastern China is dominated by Korean pine broad-leaved forest and dominated by Pinus koraiensis, which is mixed with many broad-leaved trees to form a native zonal climax community. In the last two decades, the area of pristine Korean pine forests has dwindled due to heavy harvesting, and there is not much left now. Coupled with the natural regeneration of Korean pine forest is very difficult, artificial renewal is very slow, so go down the risk of extinction. In order to promote the rapid development of Korean pine forest, there are many urgent problems to be solved. The pest problem is one of them. To this end, we have conducted a series of investigations on insect pests of Korean pine forest since 1974. First of all, we investigated the relationship between bark and insect pests in the Korean pine plantation. Then we studied the microspore-damaged aphids on the cuttings of the Korean pine plantation. At the same time, we studied on behalf of Heilongjiang Province Ecological Society Organizational forces Xiaoxing’anling forest zone ridge and five battalion two natural
