摘要/Abstract

摘要： 2003～2005年对纯林和混交林中的黑松、马尾松、湿地松诱木按1 m一个区段进行全株解剖，解剖的松墨天牛和花绒坚甲的资料用聚集强度的5种指数测定空间格局.两种林分3种松树上，松墨天牛和花绒坚甲水平分布的聚集强度指数均为扩散系数C＞1,扩散指数I_δ＞1，久野指数C_A＞0,丛生指数I＞1，聚块性指数I_w＞1,表明两者水平分布均为聚集格局，两者水平分布格局一致.垂直分布除混交林马尾松树上的花绒坚甲为聚集分布外，其余均为均匀分布，5种聚集强度指标均是C＜1,I_δ＜1，C_A＜0,I_w＜1,I＜0，花绒坚甲与松墨天牛三维空间分布格局一致，前者对后者在空间上有追随关系.

Abstract: In 2003～2005, the Monochamus alternatus infected Pinus thunbergii, P. massoniana and P. elliotii in pure and mixed forests were selected as attractants and dissected with one meter section manner, and five aggregation indices were used to analyze the spatial distribution patterns of M. alternatus and its natural enemy Dastarcus helophoroides. The results showed that M. alternatus and D. helophoroides had the horizontal distribution indices of diffused coefficient C＞1, diffused index I_δ＞1, Kuno index C_A＞0, clump intensity index I＞1, and swarm index I_w＞1 in the two stands, suggesting their aggregated horizontal distribution patterns, and except D. helophoroides on the P. massoniana in mixed forest appeared assemble vertical distribution, these two insects all had an even vertical distribution, with their C＜1, I_δ＜1, C_A＜0, I_w＜1, and I＜0. The spatial distribution patterns of M. alternatus and D. helophoroides were consistent, and the latter was spatially following the former.
