本文对华山松木蠹象为害木分级、蛹的空间分布型、抽样技术以及发生与环境关系进行了研究。结果表明，华山松木蠹象为害木可分为４ 级：正常木、初侵染木、近枯死木、枯死木。蛹的空间分布型为聚集分布。抽样部位以树干下部为最佳。用逐步回归分析方法，通过计算机处理调查数据得出，在９５ ％ 的可靠性下，影响华山松木蠹象种群数量的主要环境因子为林木生长势
In this paper, we studied the classification of Pinus armandi as the classification of harmful wood, the spatial distribution of pupae, the sampling techniques and the relationship with the environment. The results showed that P. armandii could be divided into four grades: normal wood, infested wood, dead wood and dead wood. The spatial distribution of pupae is aggregated distribution. Sampling site to the lower part of the trunk is the best. By means of stepwise regression analysis and computerized survey data, it is concluded that under the 95% reliability, the main environmental factors influencing the population of Pinus armandi population are tree growth potential
