摘要
2001年5-9月对福建省古田县单季稻田周围杂草地生境的节肢动物群落进行系统调查.结果表明:(1)稻田周围的杂草地生境贮存着丰富的天敌资源,对稻田害虫天敌种群的保存和发展有重要作用;(2)杂草地生境节肢动物群落的物种丰富度、个体数量和多样性呈现出在水稻生长前期(拨节期前)降低,在水稻生长后期增高的趋势.
A systematical survey focusing on arthropod community living in the weed habitat around a single cropping rice field was carried out in Gutian county, Fujian province, from May to September 2001. The species richness, dominance, diversity and their fluctuations of the arthropod community were studied. Resource of natural enemies was rich in the weed habitat and it plays an important role in the survival and development of the natural enemies of rice insect pests. The species richness, dominance, diversity diminished in the prophase of rice growing and increased in the anaphase.
