内蒙古乌拉特前旗大斑啄木鸟与光肩星天牛生态位分析

Niche analysis of Dendrocopos major and Anoplohora glabripennis in Wulat Front Banner,Inner Mongolia

为了解大斑啄木鸟与光肩星天牛的种群动态关系，于2005年6～10月对大斑啄木鸟和光肩星天牛共存的典型栖息地进行了调查。综合分析了大斑啄木鸟与光肩星天牛在种群增长的时间生态位和树木垂直、水平等方向的空间生态位上的关系。结果表明，光肩星天牛生态位的变化，能引起大斑啄木鸟取食及生态位的相应波动。

In order to know the relation of population dynamics between Dendrocopos major and Anoplophora glabripennis, the typical habitat which Dendrocopos major and Anoplophora glabripermis are coexistence from June to October, in 2004 was researched. Through overall analysis, the relation of Derutrocopos major and Anoplophora glabripennis on temporal niche of population growth and spatial niche of trees＇ vertical and horizontal direction was studied. The result showed that the change of Anoplophora glabripennis in niche could cause appropriate fluctuation of Dendrocopos major in niche and feeding.
