| 摘 要： | 通过野外定位定量观测和理论建模分析，对羊草地上部生态场的场特征函数（生态势）及其二维图形进行了研究．结果表明，羊草地上部生态场的作用大小与场源羊草的相对生长速率成正比，与所处的资源利用效力成反比，与生态势消减系数成正比，种群密度变化影响个体生态势的大小，二维图形能够反映羊草生态场的行为特征变化．

| Abstract: | The field characteristic function (ecological potential) and its two-dimensional graphs ofaboveground ecological field of A. chinense are studied through fixed field experiments andtheoretical modelling analysis. The results show that the action strength of abovegroundecological field of A. chinense is positively related to its relative growth rate and to the extinction coefficient of ecological potential, but negatively to the utilization efficiency of lo cational resources. Population density affects the ecological potential of individuals, andtwo-dimensional graphs can reflect the dynamic characteristics of ecological field behavior. |
