Based on the data of plant ecological field studies, this paper reviewed the conception of ecological field, field eigenfunctions, graphs of ecological field and its application of ecological field theory in explaining plant interactions. It is suggested that the basic character of ecological field is material, and based on the current research level, it is not sure whether ecological field is a kind of specific field different from general physical field. The author gave some comments on the formula and estimation of parameters of basic field function-ecological potential model on ecological field. Both models have their own characteristics and advantages in specific conditions. The author emphasized that ecological field had even more meaning of ecological methodology, and applying ecological field theory in describing the types and processes of plant interactions had three characteristics: quantitative, synthetic and intuitionistic. Field graphing might provide a new way to ecological studies, especially applying the ecological field theory might give an appropriate quantitative explanation for the dynamic process of plant populations (coexistence and interference competition).
基于植物生态野外研究的数据，本文综述了生态场的概念、场特征函数、生态场图及其在解释植物相互作用方面的应用。研究表明，生态场的基本性质是物质性的，基于目前的研究水平，尚不确定生态场是否是一种不同于一般物理场的特殊场。作者对生态场基本场函数——生态势模型的公式及参数估计进行了评述。两种模型在特定条件下都有各自的特点和优势。作者强调，生态场更具有生态方法论的意义，将生态场理论应用于描述植物相互作用的类型和过程具有定量、综合和直观三个特点。场制图可能为生态学研究提供一种新方法，特别是应用生态场理论可能对植物种群的动态过程（共存和干扰竞争）给出恰当的定量解释。
