山东栎林的动态

THE DYNAMICS OF THE OAK FOREST IN SHANDONG PROVINCE

山东栎林的主要特征于第三纪时已基本形成,并深受第四纪气候变迁的影响,群落特征表现出古老性、残遗性、热带性和复杂性。栎林为演替上的顶极群落,是典型的地带性植被类型;它是由多个落叶阔叶树种组成的混交林,而人为营造的单优势栎林(纯栎林)不是最稳定的群落,为此,必须进行合理的经营管理。

In the evolution of the geological history, the main characteristics of the oak forest in Shandong Province took shape on th*e whole in Tertiary and were profoundly effected by the climatic changes since Quaternary. But the oak forest still displays ancient, relic, tropical and complex natures. In the succession syndynamics, the oak forest comprising a numerous tree species is climax. But the single species dominant oak forest, planted by humanity, is not the most stable phytocoenosium. The oak forest must be managed rationally in this connection.
