摘　　要：通过理论分析与野外实验，本文建立了羊草个体与种群地下部生态场的势函数（生态势）模型，由此模型，分析了羊草个体在不同种群密度状态下，生态势的大小变化，并根据此模型，应用计算机绘制了地下部生态场的二维图形模式。作者从数学模型与图形两个方面分析了；羊草地下部生态场作用大小；不同密度种群的个体生态场生态势变化；羊草地下部生态场的季节性变化等，从而揭示了羊草个体与种群地下部生态场行为的特征、行为变化及其规律性。In this paper authors put forward the ecological potential model of the underground ecological field of Aeurolepidium chinense population by the field experiments and thoretical analysis. There are the some analysis to the potential values in different population density conditions, as well as the seasonal changes for the population. Author also gave the graphic explaination for the two-dimensional behavior graphs drawn by the computer. The results showed that the ecological potential is related to plant growth rate, resource utilization effidency, and root biomass, radius and the interaction distances.
