摘要
通过季节性的观察,系统研究了长白山植物群落、昆虫群落多样性及它们之间关系。结果表明,植物群落物种丰富度指数与植食性昆虫丰富度指数呈负相关,而与捕食性天敌昆虫丰富度指数呈正相关,与寄生性天敌的丰富度指数呈负相关;昆虫群落的均匀度与植物群落的均匀度相关显著。植物群落的多样性指数与捕食性、寄生性天敌的多样性指数呈正相关,而与植食性昆虫的多样性指数呈负相关,这表明植物群落的多样性影响昆虫群落的多样性。
The plant, insect community and their correlation were studied systematically through seasonal research in this paper. The results showed that the index of species richness of forest plant community was negatively correlated with community of defoliator and parasitic insects, positively correlated with predatory insect community, The evenness of insect was related to that of plants closely, Annual species diversity index of forest plant community showed a closely positive correlation with that of predatory and parasitical insect community, and a negative correlation with defoliator insect community. Distinct correlation was found between forest plant and forest insect community suggesting that complexity of forest plant community had significant influence on diversification of insect species composition.
