| 摘 要： | 对甘蓝生态系统中节肢动物群落的组成和时空序列动态及相关性进行了研究,结果表明,甘蓝田中节肢动物群落种类丰富,发生数量大;在甘蓝生态环境中,节肢动物群落各营养层在时间和空间上所占的比例是不同的,但在同一营养水平上分布是相关的,这种相关性揭示了中性昆虫在群落食物网中起着重要的作用,可见在综合防治甘蓝害虫时既要保护和利用寄生和捕食性天敌,又要保护和利用中性昆虫。

| Abstract: | The structure and temporal and spatial dynamic and their relation of arthropod community in cabbage ecosystem were studied.The results showed that the species and the number of individual in cabbage field were abundance.In the cabbage ecosystem,the proportions of guilds of the arthropod community were different temporal and spatial niche,and some relation at the same nutrient level,the relation revealed that the neutral insects played an important role in the food web of the arthropod community.For these reasons,the protection and use of natural enemies and neutral insects were equally important in the control of cabbage pests. |
