正相互作用

由此可见，本研究不支持胁迫梯度假说，即植物相互作用未沿着胁迫梯度由竞争转向正相互作用。

Hence , this study did not support Stress Gradient Hypothesis ( SGH ), namely plant-plant interaction did not change from competition to positive interaction along stress gradients .

而且，胁迫梯度假说（SGH）也预测了促进作用与竞争作用沿着环境梯度的相互变化，这也刺激了大量关于正相互作用的研究。

Moreover , the ' stress-gradient hypothesis '( SGH ) predicting the shifts between facilitation and competition along environment gradients has stimulated the bulk of studies about facilitation .

正相互作用对非生物胁迫具有明显的抵消效应，因此在密度依赖死亡过程中趋向于维持空间格局的聚集程度。

然而与单层模型的结果不同的是双层模型预测胁迫使自疏线显著地变平，而正相互作用抵消了胁迫效应从而使自疏线变陡。

Different from the one-layer model results , the two-layer model predicted that high stress dramatically flattened self-thinning lines , whereas facilitation again counteracted the stress , thus steepened thinning lines .
