中文摘要:采用陷阱法系统调查棉田各发育期的蜘蛛群落分布型,运用5种聚集度指标、Taylor的幂法则以及m*-x-的回归关系综合分析。结果显示:(1)陷阱法所采集的蜘蛛绝大多数为游猎型蜘蛛。(2)棉田游猎性蜘蛛群落在整个棉花发育期都呈随机分布。
英文摘要:The spatial distribntion patterns of the spider community in a cotton field were surveyed by pitfall traps and analyzed by five aggregated indices, power law of Taylor and regressive relation by M*-test. The results indicated that (1)the most of trapped s
