亚热带天然混交林森林生态系统经营的决策模型

Decision model of forest ecosystem in subtropical nature mixed forest

根据生态系统经营的目的,提出了森林生态系统经营决策的6个空间结构因子,并建立了以顶极群落为目标,以维持生态系统健康和功能持续为目的,形成林木空间均匀分布为特征的森林生态系经营决策模型。结果表明,所建决策模型可以极大地改善系统的空间结构,有利于系统功能的完整和健康。

According to the purpose of forest ecosystem management, the six spatial structure were created. The decision model on forest ecosystem management was constructed to reach the goal of climax community and meet the purpose of maintaining health and functions standing of forest ecosystems. The characters of uniform distribution of trees in forest ecosystems was set in the model. In practice, the spatial structures, health and functions of forest ecosystem could be improved intensively by the decision model.
