| 摘 要： | 本文对食物链“蒲公英—蝌蚪—鳝鱼”的物质流和能量流作了定量分析。结果表明：该食物链经济产品的物质、能量转化效率较低，生物量转化效率为1.1％，能量转化效率为0．8％，N、P转化效率分别为3．1％、1．5％。但该食物链刺激鳝鱼食欲，有利于鳝鱼繁殖。

| Abstract: | A quantitative analysis on material and energy flowing of food chain of dandelion-tadpole-mud eel is reported in this paper). It is shown that the economic products of the food chain had lower material and energy transforming efficiency. The biomass, energy, N and P transforming efficiency were 1.1 %, 0.8 %, 3.1 % and 1.5% respectively. However the food chain can stimulate the appetite of mud eels, which is beneficial to mud eels breeding. |
