Abstract: Sampling techniques for Korean pine (Pinus koraiensis) forests mixed with deciduoud trees in the Lesser Xiaoxingan Mountains were studied. Plotless sampling method (point centered quarter method) is considered to be a kind of suitable method for this kind of vegetation. The study was done by examining four types of forest communities. Results show that the minimum points of plotless method are 16 to 18, the distance between two neighborhood points and that between two sampling lines is 15 and 20 meters, respectively. The data from 16--18 points is analogous to that from 600m2 of plot. The minimum area of understoreys is 28–32m2, which is 7 or 8 2 × 2 m quardrats distributed randomly or mechanically.
