| Abstract: | The influence of slope and aspect on Dendroctonus valens LeConte occurrence were studied. The results showed that, in terms of aspect, the top peak of slope suffered heaviest damage with the damage rate reaching 40. 89%. Regarding slope, the damage rate reached 17.79% and 14. 98% respectively on gentle slope and steep slope, indicating gentle slope suffers less damage than steep slope. |
