摘  要：
以危害杨树的云斑白条天牛种群为调查对象,对其危害特点与空间分布进行调查研究。结果表明,云斑白条天牛的危害程度与杨树的树龄、胸径均呈抛物线式相关,危害程度随树龄、胸径的增大先上升后下降,4~8年生树龄、12.0~21.9cm胸径的杨树受害最严重;不同林地环境下的杨树受害程度也不一样,渠道林受害最重,村庄林和道路林次之,片林较轻。通过频次比较法分析表明,危害杨树的云斑白条天牛幼虫的空间分布型符合负二项分布,为聚集分布。

摘  要：
In the paper,it was studied that damage characters and spatial distribution of Batocera lineolata population,attacking poplars seriously. It was showed by survey that the relation between damage and host popolar's tree age and diameter breast height,were both parabolic type,damage degree increased at first and then decrease,with increasing of host popolar's tree age and diameter breast height. The host poplars of tree age 4 ~ 8 annual and diameter breast height 12. 0 ~ 21. 9 cm were attacked most seriously. The damage degree was different of the poplars in different forest types,channel forest damaged most seriously,village and road forest took second place,patch forest was light. The spatial distribution pattern of B. lineolata population was analyzed with frequency statistical method. The results showed that the spatial distribution pattern of B. lineolata larva in poplars was negative binomial distribution,namely aggregation distribution.
