研究了芦苇（Phragmites australis（Cav.）Trin.来自Steud.，并对对流的机理进行了描述。实验证据表明，这些因素，如低相对湿度（RH），光，大叶鞘面积，增加湿度诱导的对流;和那些增加文丘里对流，如高风速，进行了审查。实验和数学模型证明了对流通风优于扩散通风的上级通气效果及其对根际的影响。
The pathways of diffusive, humidity- and Venturi-induced convective ventilations in Phragmites australis (Cav.) Trin. ex Steud., and the mechanisms of the convections are described. Experimental evidence, indicating those factors, e.g. low relative humidity (RH), light, large leaf-sheath area, which increase humidity-induced convection; and those which increase Venturi convections, e.g. high wind speed, are reviewed. The superior aerating effects of convective as opposed to diffusive ventilation within the plant and their influence on the rhizosphere are demonstrated experimentally and by mathematical modelling.
