Red turpentine beetle(RTB), Dendroctonus valens LeConte was a destructive forest invasive species in China, it mainly attacks Pinus. tabuliformis and P. bungeana. So far it has spread rapidly to the provinces of Shanxi, Hebei, Henan and Beijing since its first outbreak in Shanxi province in 1998, and caused extensive tree mortality. In order to further study the spatial distribution of its population, the spatial characteristics of D. valens population were analyzed by using geostatistical methods in the pure P. tabuliformis forest and mixedwood stands which at different damage levels. The result showed that the damage level caused by D. valens differed significantly in the two woodlands. Only 4.9 % of trees in lightly-infested woodland were infested compared with 23.6 % infested individuals in heavily-infested woodland. Analysis of the isotropic variogram indicated that the distance of spatial dependence of D. valens was 49.400m in the lightly-infested levels of pure P. tabuliformis forest, 47.400m in the heavily-infested one and 73.820m in the mixedwood stands, while the intensity of local spatial continuity was 0.824, 0.582, 0.762 respectively in the above stands. Intense spatial aggregation distribution pattern of D. valens were observed in the lightly-infested level and heavily-infested level of pure P. tabuliformis forest, while random distribution was observed in the mixedwood forest. It concluded that the difference of spatial distribution of D. valens not only existed in different damage levels of pure forest, but also in different stands types. According to the spatial distribution of its population, the spatial sampling technique of D. valens was also studied, and then compared with traditional sampling technique.
