摘　　要：Study on the sampling technique of Pineus armandicola and the relationship between the occurrence of it and environmental factors was conducted in 222 Forest Farm, Dongchuan, Yunnan Province. It was found that the best sampling site is the middle east of the crown canopy. The best sampling number is calculated as the model: N =127.25/ +1.87. Using Latin square orthogonal design, the relationship between the occurrence of Pineus armandicola and environmental factors was revealed. Among the investigated environmental elements, the most important key factor to influence the variance of population density is the tending status of the woods. Other key factors are successively slope direction, elevation and canopy density. Advice on how to control Pineus armandicola is also given.Study on the sampling technique of Pineus armandicola and the relationship between the occurrence of it and environmental factors was conducted in 222 Forest Farm, Dongchuan, Yunnan Province.
