Healthy Managemennt Mode of Poplar-Birch Secondary Forest in Jingouling

通过分析长白山杨桦次生林演替过程及其林分结构特征,提出杨桦次生林健康诊断评价技术和健康经营关键技术,构建自适应经营模式。采用定性判断与定量化、模型化相结合,野外调查与科学推理相结合等系统整合研究的理论和方法,开展系统的长白山杨桦次生林健康经营模式研究。通过对杨桦次生林健康经营目标、原则、模式、调整步骤以及调整技术进行整合研究,提出了易于操作的动态的杨桦次生林健康经营模式,并对杨桦次生林的各演替阶段,分别提出了具体的经营目标体系,为杨桦次生林的可持续经营提供了理论依据。

By analyzing the succession process and stand structural characteristics of the poplar-birch sec ondary forest （PBSF） in Changbai Mountain, the diagnostic evaluation method and the key technologies of healthy management of PBSF were proposed. Methods of combining qualitative judgment and quantitative modeling, field survey and scientific reasoning were adopted. Through studying the business objectives, principles, patterns, the adjustment procedure and technologies, a healthy, easy to operate and dynamic management model of PBSF was proposed. Specific operation of the target system for the successional sta ges of PBSF was proposed and a theoretical basis for the health management of PBSF was provided.
