摘 要 ：用森林动态林窗模型 FORET1模拟了暖温带落叶阔叶林的长期变化特征。模型参数取自暖温带地区长期森林研究和经营的历史数据 ,对过去数据中缺少的参数进行了实地测定 ,并用观测的数据对模型作了检验。结果表明模型能较好地模拟暖温带落叶阔叶林的长期动态变化特征。通过模拟可以看出 ,森林的净初级生产力没有明显变化规律且极度不稳定 ,峰值出现在30 a左右 ,相似于世界上其它地区森林动态格局变化 ,生物量格局呈循环状态变化 ,循环周期大致在 110 a左右。

Abstract:A warm temperate deciduous forest in Dongling Mountain of Beijing was simulated with forest gap dynamics model, FORET1, in order to predict its future changes. The model parameters were derived from both historical and currently measured data; and the model was tested against observed data. Results showed that the model simulation of forest species composition, biomass and production matched well with observed data. Model simulation of the dynamics of this warm temperate deciduous forest indicate that the ...
