| 摘 要： | 2009年2月对广东韶关丹霞山风景区巴寨景点蚁狮Myrmeleon(Morter)sagax(Walker)种群进行了调查,采用了5种聚集度指标以及Taylor的幂法则与Iwao的m*-m直线回归方程进行计算和分析。结果表明:该地区蚁狮种群空间格局在局域斑块尺度属于均匀分布,种群密度越高分布越均匀。蚁狮种群的生境特点、捕食行为、种内竞争等可能对其种群密度及空间分布格局有重要影响。

| Abstract: | The population of Myrmeleon(Morter) sagax(Walker) at Bazhai scenic spot in Danxia Mountain of Shaoguan City,Guangdong Province,was investigated in February,2009.Five aggregation indices,Iwao's way(regressive relationship with m* -m),and power law of Taylor were used to evaluate the spatial distribution pattern of ant-lions.The results showed that ant-lions were spatially evenly in their distribution range.The higher population density,the more evenly distribution was observed.The evenly distribution pattern... |
