摘  要：
为探索不同稻田生态系统调控功能差异的机理,连续2年通过黄板诱集取样法,研究了有机稻田和化防稻田中白背飞虱Sogatella furcifera、褐飞虱Nilaparvata lugens与其主要天敌类群的时间生态位宽度及生态位重叠变化规律。研究结果表明,2010年黄板诱集法取样下有机稻田中稻飞虱与主要天敌类群的生态位重叠值平均值(0.5492)大于化防稻田(0.3777),有机稻田中主要天敌类群的生态位宽度平均值(0.4967)大于化防稻田(0.4118);2011年黄板诱集法取样下有机稻田中稻飞虱与主要天敌类群的生态位重叠平均值(0.5919)大于化防稻田(0.4252),有机稻田中主要天敌类群的生态位宽度平均值(0.5022)大于化防稻田(0.4090)。这表明有机稻田生态系统相比较于化防稻田生态系统而言,在时间生态位层面是通过影响稻飞虱和天敌类群的时间生态位宽度指数及其天敌与稻飞虱的生态位重叠值,来增强稻田节肢动物群落系统的自我调控能力。

摘  要：
In order to explore the differences of regulation mechanisms between organic and chemical control paddy field ecosystems,the dynamics of the temporal niche breadth and overlap of whitebacked planthoppers,brown planthoppers and their natural enemies in the 2 ecosystems were investigated in this study. Insects were sampled by the yellow board traps in 2010 and 2011. The results showed that the average temporal niche overlap and breath between rice planthoppers and their natural enemies in organic fields( 0. 5492 and 0. 4967,respectively) were larger than those in chemical control paddy fields( 0. 3777 and 0. 4118,respectively) in 2010. A similar pattern was also observed in 2011,the temporal niche overlap and breath were larger in organic fields( 0. 5919 and 0. 5022,respectively) than those in chemical control paddy fields( 0. 4252 and 0. 4090,respectively). Compared to chemical control paddy fields,the arthropod populations in organic paddy fields were enhanced by increasing temporal niche breath and overlap between rich planthoppers and their natural enemies.
