摘要: 应用空间明晰景观模型LANDIS 6.0 PRO,以浙江天童国家森林公园常绿阔叶林为研究对象,根据天童国家野外观测站的长期研究和观测数据对LANDIS模型进行参数化,模拟无干扰情况下常绿阔叶林在未来500年间的演替动态,分析优势种和主要景观类型的空间分布以及年龄结构组成,揭示了常绿阔叶林演替的规律.结果表明: 研究区物种的交替多发生在常绿阔叶林阶段之前,马尾松、白栎和枫香等先锋物种在演替初期占有较大比例,但随着时间的推移逐渐退出,木荷和栲树等物种在演替后期占有较大优势,并逐渐发展成木荷栲树顶极群落;无干扰的情况下,在演替前期,群落多由幼龄林构成,后期则多以成熟林或过熟林为主,群落更新能力不足.LANDIS模型可应用于我国东部常绿阔叶林的景观动态模拟,今后的研究应结合亚热带常绿阔叶林的复杂性和多样性,对模型结构和模型参数进行完善和
改进.

Abstract: By using spatially explicit landscape model (LANDIS 6.0 PRO), and parameterized this model with the long-term research and observation data of Tiantong National Station of Forest Ecosystem Observation and Research, this paper simulated the natural succession of evergreen broad-leaved forest in Tiantong National Forest park, Zhejiang Province in the future 500 years, analyzed the spatial distribution and age structure of dominant species and major landscapes, and explored the succession pattern of the evergreen broadleaved forest. In the park, the species alternation mostly occurred before the stage of evergreen broad-leaved forest. Pinus massoniana, Quercus fabric, and Liquidambar formosana occupied a large proportion during the early succession, but gradually disappeared with the succession process. Schima superba and Castanopsis fargesii took the main advantage in late succession, and developed to the climax community. Under the conditions without disturbances, the community was mainly composed of young forests in the early succession, and of mature or over-mature forests in the late succession, implying the insufficient regeneration ability of the community. LANDIS model could be used for simulating the landscape dynamics of evergreen broad-leaved forest in eastern China. In the future research, both the model structure and the model parameters should be improved, according to the complexity and diversity of subtropical evergreen broad-leaved forest.
