【摘要】 应用生物地理统计学的原理和方法 ,对 2块危害程度不同的柏木林分中的鞭角华扁叶蜂滞育幼虫的空间格局进行研究 ,结果表明 :受中度危害的柏木林分中的鞭角华扁叶蜂滞育幼虫有明显的空间依赖性 ,其变程为 15 77m ,半方差函数模型为指数型 ;受重度危害的柏木林分中的鞭角华扁叶蜂滞育幼虫则表现纯粹周期性变化的空间现象 ,其周期性为 6 80 6 2。同时对鞭角华扁叶蜂滞育幼虫种群的空间抽样技术进行了研究更多还原

【Abstract】 The principle and method of biogeostatistics were used to study the spatial pattern of diapause larva of Chinolyda flagellicornis in Cupressus funebris stands with different damage degrees.The results show that the diapause larva appeared obvious spatial dependence in medium damaged Cupressus funebris stand,the range is 15.77 m,the half variance function is a exponential one,while the diapause larva of Chinolyda flagellicornis in heavy damaged Cupressus funebris stand appeared pure periodic change,the period was 6.806 2. The spatial sampling technique of diapause larva population of Chinolyda flagellicornis was also studied.更多还原
