摘要: 为了明确萧氏松茎象发生与林下非寄主植物之间的关系,基于2×2联列表,应用方差分析、χ2统计检验、Ochiai指数、Dice指数和Cramer指数等系列技术,分别对萧氏松茎象与湿地松林下植被中前30个优势种群间的总体相关性、各种对间联结显著性和关联强度进行了定量的测定。结果表明萧氏松茎象与林下杂灌层植物间联结性不显著,说明萧氏松茎象的发生与非寄主植物间没有直接的内在的联系。

Abstract: In order to realize the interspecific correlation of Hylobitelus xiaoi occurrence and understory nonhost plants of Pinus elliottii Forests, the interspecific correlation of Hylobitelus xiaoi and understory nonhost plants in Pinus elliotii forests in Jiangxi province was analyzed in this paper by using 2×2 table, variance analysis, χ2test, association coefficient, Ochiai index, Dice index and Cramer index were used. The results showed that the interspecific correlation of Hylobitelus xiaoi and understory nonhost plants was not obvious. It indicated that the occurrences of Hylobitelus xiaoi was not directly related to the these nonhost plants.
