摘　　要：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。Modified SPACE Model was used to simulate the birch secondary forest from the clear cut in 1950s. The results show that under natural succession it will change to the stand dominated by Korean pine after seventy years, and under dynamic cutting it will change to stable mixed stage after forty years. The sustainable management strategy of secondary forest was put forward.
