Experiments on mixed models of seed-timber stands of Pinus koraiensis was conducted in this paper. The results indicated that: Planting Pinus koraiensis and Larix Kaempferii mixed stands by line and when Larix Kaempferii reached technical commercial values and was cut over, investment could be got back and better profits be obtained. Thus, investment cycle was shortened, and the existing issues in production, namely, no benefit was obtained before Pinus koraiensis bore seeds was resolved.
