中文摘要：
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
英文摘要： 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 of ant\|lions population might be caused by habitat condition, their prey behavior and intraspecific competition.
