The author investigates the damage degree of Red Turpentine Beetle（RTB）to Pinus tabulaeformis in Shanxi Province,and analyzes these comparisons between thinned and non-thinned forest,tapped and non-tapped forest,burned and non-burned forest,mixed forest and pure forest,forest with different rate of coverage,sunny slope forest and shady slope forest.The results show that RTB made a greater harm to thinned forest;the difference between tapped and non-tapped forest was significant（P=0.001）,RTB had higher harm on the tapped forest;the harm was bigger on the forest burned than on the contrast;the RTB harm difference between mixed forest and pure forest was not significant（P=0.828）,mixed forest cannot reduce the damage;the average rates of forest pest are incomplete same in forest with different rate of coverage（P0.0001）,those of coverage rate of 0.3,0.4 have the most serious disaster of forest pest;the variation between sunny slope forest and shady slope forest was remarkable（P=0.000 1）;the RTB harm was heavier on the sunny slope forest than on the shady slope forest.
