摘要: 对不同生长势林区内的松墨天牛种群密度和松材线虫发病程度的研究表明,树木生长势(x)分别与松墨天牛种群密度(y)、松材线虫发病程度(z)呈负相关,其线性回归方程分别为:y=1793.771-16404.7x;z=31.80989-21.9274x.相关系数分别为r=-0.8319和r=-0.8770.而松墨天牛种群密度(y)与松材线虫发病程度(z)呈正相关,其线性回归方程为:y=-407.0611+70.51478z;相关系数为r=0.9864.

Abstract: The results showed that the growth potential of pine (x) is negative related to the population density of Monochamus alternatus (y) and the pathoyenecity of Bursaphlenchus xyloophilus (z). But the population density of Monochamus alternatus is positively related to the pathogenicity of Bursaphlenchus xyloophilus. Three linear equations regression line were established as y=1793.771-16404.47x,z=31.80989-241.9274x, y=-407 611+70.51478z.Correlation coefficient is -0.8139,-0.8770 and +0.9864 respectively.

Key words: Pine growth potential, Monochamus alternatus, Population density, Pathogenicity, Bursaphlenchus xyloophilus, Correlation coefficient
