| 摘 要： | 利用生物地理统计学的原理和方法研究鞭角华扁叶蜂滞育幼虫的虫口密度与其所处的空间位置之间的关系，创建了鞭角华扁叶蜂滞育幼虫虫口密度的半方差函数模型.在此基础上，用不同空间位置上的已知种群密度观测值估计其他空间位置上的未知种群密度，取得了令人满意的估计效果。

| Abstract: | Principles and methods of biogeostatistics were applied to study the relationship between the population density of the diapause larva of Chinolyda flagellicornis and its spatial position.The semivariance function model of pupulation density of the diapause larva was established.Based on it,the assessment of unknown population density in other spatial position with the observation value of the known population density in different spatial positions was satisfactory. |
