基于对松嫩草原优势物种羊草(Leymus chinensis)及其主要伴生种的空间分布格局、植物种间关系对割草的响应,以及羊草、芦苇(Phragmites communis)对营养和胁迫的适应性与种间关系的研究,探讨了植物竞争和共存的潜在机制。野外调查和控制实验主要结论如下。
The mechanism of plant competition and coexistence was investigated by studying the spatial distribution pattern and the response of inter-specific competition to cutting between L. chinensis and its main companion species ; more particularly, the relationship between the adaptation of L. chinensis and Phrgmites cornrnunis, and their inter-specific interaction. Main conclusions of field investigation and controlled experiment are as follows.
