| 摘 要： | 通过对植物个体与种群生态场定位实验研究，提出了生态场梯度的概念，并给出了植物与羊草个体生态场梯度的模型，植物生态场的场梯度是，生态场中生态势沿任意方向的变化率。羊草个体生态场梯度同羊草种群密度相关。

| Abstract: | Through a fixed case study on the ecological field of plant individuals and populations. theconcept of ecological field gradient is put forward, and the ecological field gradient modelsof plant and Anewolepidium chinense individuals are established. The variation forms ofA. chinense crown field gradient conform to the Rayleigh distribution, and there is onemaximum value at the point r=. The A. chinense root system field gradient variesin a complex distribution, and there are two maximum values at the points r=0 and r=a.The ecological field gradient of A. chinense individuals is related to its population density. |
