| 摘 要： | 尝试将生态位理论应用到分析环境条件变异和人类干扰活动对天敌和猎物关系的影响，通过与非涝渍稻田对比分析，发现涝渍害综合作用对稻飞虱及其节肢类天敌的时间生态位，空间生态位以及时间一空间生态位均产生深刻的影响，涝渍害的作用使节肢类天敌和稻飞虱空间生态位宽度普遍缩小，使涝渍地各物种间空间生态位重叠亦普遍减小；使除稻红瓢虫和球腹蛛外的天敌时间生态位宽度扩大；各天敌和中性昆虫与飞虱的空间一时间生态位重叠亦普遍缩小，还讨论了这种影响的机制及改良的生态对策。 |

| Abstract: | The paper tried to apply the niche theory to the analysis of the effect of varied environmental conditions and human disturbances on the relationship between rice planthoppers and their natural enemies. By contrasting with non -waterlogged paddy fields,it was found that waterlogging had great influence on spatial niches .temporal niches and spatial - temporal niches of rice planthoppers and their arthropod natural enemies. Under the stress of waterlogging, the spatial niche width of the planthoppers and their natural enemies was generally narrowed;And their spatial niche overlaps decreased accordingly. The temporal niche width of natural enemies except Theridiidae and Coccinellidae was broadened; The spatial - temporal niche overlaps of planthoppers and their natural enemies and neutral insects were also narrowed. The influencing mechanisms and ecological strategies of ameliorating were also discussed in the paper. |
