本文用经过验证的ＺＥＬＩＧ模型对长白山区生长的沼泽土上的落叶松林进行模拟，模拟结果表明：该类落叶松林是一种稳定的土壤顶级群落，该群落的稳定性表现在群落组成树种及各树种组成比例的相对稳定性。而该群落的其它特征（如林分密度、生物量、叶面积指数等）是呈周期性波动的，林分周期性波动维持了该群落的稳定性，该群落稳定的另一个原因是落叶松、白桦等阳性树种能在林下更新。
In this paper, a validated ZELIG model was used to simulate the larch forest growing in swamp soil in Changbai Mountains. The simulation results show that this kind of forest is a stable top soil community. The stability of the community is reflected in the composition of the community tree species and The relative stability of species composition ratio. The other characteristics of the community (such as stand density, biomass, leaf area index, etc.) are cyclical fluctuations, cyclical fluctuations in the community to maintain the stability of the community, another reason for the stability of the community larch , Birch and other positive species can be updated under the forest.
