采用SPACE模型对20世纪50年代的皆伐地，现已形成次生白桦林进行动态模拟。结果表明任其自然演替，可在70a后逐渐形成红松占优势的林分；而经过动态采伐，可诱导在40a后形成稳定的混交林状态，并提出了相应的次生林可持续经营对策。
Based on the SPACE model, the secondary birch forest has been dynamically simulated for the clear-cut fields in the 1950s. The results showed that natural succession could gradually dominate the stands of Pinus koraiensis after 70 years. After dynamic harvesting, the state of stable mixed forest could be induced after 40 years and the corresponding sustainable management strategies for secondary forests were proposed.
