该文以ZELIG模型的框架为基础 ,结合长白山阔叶红松林的特点 ,建立了模拟长白山阔叶红松林动态和经营管理的ZELIG .CBA(ZELIGmodelforChangBaiArea)模型。ZELIG .CBA模型由 4个子模型组成 :树木生长子模型、树木更新子模型、树木枯死子模型和森林经营管理子模型。经过验证 ,ZELIG .CBA模型模拟阔叶红松林生长的精度可达 95 %以上。皆伐迹地上森林演替的模拟结果表明 ,ZELIG .CBA模型长时间尺度运行结果是稳定的 ,可很好地反映阔叶红松林的动态变化规律。择伐模拟试验表明 ,阔叶红松林轮伐期 3 0a时 ,最佳择伐强度为 3 0 %。模型验证及模拟试验显示出ZELIG .CBA模型可运用于研究长白山阔叶红松林动态和不同森林经营措施下阔叶红松林的反应。
Based on the framework of ZELIG model and combining with the characteristics of broad - leaved Korean pine forest in Changbai Mountain, a ZELIG CBA model for simulating the dynamics and management of broad - leaved Korean pine forests in Changbai Mountain was established. The ZELIG. CBA model consists of four sub-models: the tree growth sub-model, the tree update sub-model, the tree fubus model and the forest management sub-model. After verification, ZELIG. CBA model can simulate the growth of broad-leaved Korean pine forest, the accuracy of up to 95%. The simulation results of forest succession on clear cut indicate that the results of ZELIG. CBA model are stable on long time scale and can well reflect the dynamic change law of broad-leaved Korean pine forest. Selective cutting simulation test showed that the optimal selective cutting strength was 30% when the broad-leaved Korean pine forest was rotated at 30a. The model validation and simulation tests show that the ZELIG .CBA model can be used to study the dynamics of broad-leaved Korean pine forests in Changbai Mountains and the responses of broad-leaved Korean pine forests under different forest management practices.
