杉木球果虫害程度与坡位的关系

The Relation between the Damaged Extent of Chinese Fir Cones Caused by Pest and Slope Positions

杉木球果虫害程度与坡位关系的研究结果如下：直观统计表明杉木球果虫害程度随坡位不同而不同，虫害最严重的是上坡，中坡次之，下坡最轻；方差分析表明不同坡位杉木球果虫害程度差异显著；多重比较分析结果表明上坡和下坡。

The relations betweent the damaged extent of Chinese fir cones caused by pest and slope positions are studied in this paper.The direct statistics indicate that the damaged extent of Chinese fir cones on different slope positions are different,which are in sequence of the uphill>the middle slope position>the downhill.Variance analysis demonstrates the damaged extent of Chinese fir cones varied significantly with the slope positions.The multiple comparison analysis indicates that their damaged extent of cones are significantly different between the uphill and the downhill,the middle position and the downhill.
