摘　　要：本文主要探讨沉水植物蓖齿眼子菜生存需求的光照适应性条件。设计试验提供植物生长所需的必要条件,比较处于不同水深度层植物的生长状况,考察因水体深度增加引起的光照减弱对蓖齿眼子菜生存的制约程度。试验表明蓖齿眼子菜光补偿深度粗略值为水体透明度下60 cm深度,即蓖齿眼子菜成活的临界水深度。Light compensation depth of Potamogeton pectinatus L. related to the light conditions for its living was conducted in the present study. The experiment investigated influence on the living of Potamogeton pectinatus L., which triggered from weaker light wavelength through deeper water. The results showed that the light compensation depth of Potamogeton pectinatus L. was found to be approximately 60 cm under layer of water where light intensity was transparency clarity, and that the light compensation depth was critical depth to living for this water plant studied.
