摘要:
 杨盾蚧是广泛分布于新疆的严重影响杨树生产栽培的枝干刺吸类害虫。利用地统计学，将克拉玛依人工林作为研究对象，结合传统方法建立回归方程对不同受害程度林分以及混交林分内杨盾蚧分布的空间格局进行分析。结果表明，不同受害程度林分以及混交林建立空间模型具有明显差异性，分别为高斯模型（中度受害纯林、混交林）、指数模型（重度受害纯林）、线性模型（轻度受害纯林）。结合Kriging法表明，杨盾蚧空间呈斑块状分布，受害程度不同的林分内杨盾蚧种群空间格局具有一定的差异，纯林与混交林之间也存在较大差别。据此，对杨盾蚧空间分布格局差异的影响因素进行相应探讨与分析，混交林较于纯林发生虫害的可能性较小，且不具有扩散性；3种不同受害程度纯林中，虫害的发生呈现空间聚集性;重度受害纯林中，通过聚集点及扩散方向可以进行有效防治指导。
Abstract:
Diaspidiotus slavonicus (Green) is a piercing-sucking pest to the tree trunks and branches.It is widely distributed in Xinjiang and seriously affected the production and cultivation of poplar trees.Taking artificial forest in Karamay as the research object,this study used geostatistics method in combination with traditional methods to investigate the spatial distribution pattern of D.slavonicus in pure and mixed poplar forests with different damage degrees.The spatial models established were significantly different among the forests studied:Gaussian model (moderately-infested pure and mixed forest),exponential model (heavily-infested pure forest),and linear model (lightly-infested forest).The combination of Kriging method indicated that D.slavonicus was in patchy distribution,Differences in spatial distribution were found not only among the pure poplar forests with different damage levels,but also among different stand types (pure and mixed forests).Based on the findings above mentioned,factors influencing spatial distribution of D.slavonicus were discussed.It illustrated that between different forest types,the possibility of the occurrence of the pest in mixed forest was lower than that of pure poplar forest,and no pest diffusivity was observed in mixed forest.The pest occurrence in pure poplar forests with three different damage levels exhibited significant aggregation distribution.For the pure forest with severe damage level,effective prevention guidance could be conducted through aggregation points and the diffusive directions of D.slavonicus.
