| 摘 要： | 三江平原池塘生态系统有7个组分：浮游植物，浮游动物，摇蚊幼虫，鲢鱼，鳙鱼，鲤鱼和有机碎屑，可用一组对时间七目微分方程组表示池塘生态系统能量流动的过程，即：dx1/dt=u1R-(b1 a1 a12 a17 a18)X1 dx2/dt=a12X1-(b2-a2 a25 a27)X2 dx3/dt=a73X7-(b3 a35 a37)X3 dx4/dt=(b4 c1)X4-a14X1-a24X2-a24X2-a74X dx5/dt=(b5 c2)X5-a25X2-a35X3-u2XF dx6/dt=(b6 c2)X6-a16(X1)-a76X7 dx7/dt=a17X1 a27X2 a37X3 aX7 a73X8-a74X7 u2xF-D根据对池塘生态系统能量流动的分室模型进行输入扰动，分析表明：浮游植物光能利用率的提高及投料的增加可使鱼产量大幅度提高。 |

| Abstract: | There are seven components in the pond ecosystem in Sanjiang plain, they are phytoplankton, zooplankton, lavar of mosquito, siler carps, bighcads, carps, as well as organic mate-rials. There are seven calculus equations to show the process of energy convertions at acertain time in the pond ecosystem.According to the input interfenrence to the model of energy conersion in pond ecosystem, the con-clusion is that the production of the fishes increased greatly with the raising of utilisition ratio of light energy and fodder put in. |
| Keywords: | pond ecosystem energy conversion systematic control Sanjiang plain |
