摘　　要：本研究运用解剖学、组织学技术以及Spot321图像分析系统,对重口裂腹鱼消化道形态组织结构进行了定量组织学研究。结果显示:重口裂腹鱼消化道具典型肉食性鱼类结构特征,其口须和唇发达;具有能伸缩的管状口;鳃耙粗大,排列稀疏;食道粗短,皱褶发达;肠道较短,盘曲简单,肠壁内粘膜褶高度、粘膜上皮高度由前至后递减,表明肠道消化吸收功能由前肠至后肠逐渐降低,其消化道形态学结构与生理功能密切相关。The structure of the digestive tract in Schizothorax davidi was studied by the methods of anatomy,histology technology and Spot321 picture analyticl system.The results are as follows： the digestive tract of Schizothorax davidi shows the characteristics of carnivorous fishs.Schizothorax davidi with the strong barbel and lips has the tubifrom-like mouth which can contract;The gill raker arranged sparely is big and strong;The esophagus having well-developed plicamucosa is stout and short;The gut is short.The height of the intestinal plicamucosa decreases gradually from the anterior intestion to the posterior one.Therefor,the absorptive functions decreases gradually from the anterior intestion to the posterior one.The morphological characteristics of the digestive tract was closely related to the functions of the different segments in the digestive tract.
