摘 要:对马尾松纯林中动物和虫生真菌群落的调查表明 ,植食性、捕食性、寄生性昆虫和蜘蛛类群物种数分别占 51 %、1 2 %、7%和 2 6% ,益害生物个体数之比约 1∶ 1 0 .2个相似的林分或林间层次中 ,物种数、科数相等或相近 ,优势目相同 ,而且二者的植食性、捕食性、寄生性昆虫和蜘蛛类群的物种数和个体数的波动相对应地趋于一致 .主成分分析显示群落 1周年内处于“深秋准备越冬→冬眠→早春复苏→春、夏、初秋繁荣”的循环演替之中 。Investigations on animal and entomogenous fungus in pure Masson pine stands show that the species numbers of phytophagous, predatory, parasitic and spider groups are 51, 12, 7 and 26%, respectively. The ratio of beneficial to harmful organism individuals is about 1∶10. Within 2 similar stands or layers, the family and species numbers are equal to or close to each other. Their dominant orders are similar. The fluctuations of species or individual numbers of phytophagcus, predatory, parasitic and spider groups are almost the same within the stands and layers. Principal component analysis indicates that in 1 anniversary year, the community is in a state of circulating succession of 'preparing overwintering inlate autumn→hibernation→resuscitation in early spring→flourishing during spring, summer and early autumn'. The stability and the self adjusting potential of the community are quite strong.
