| 摘 要： | 阐述虾池生态系的能流结构，将虾池生态系分为两个亚系统：浮游亚系统与底栖亚系统，在浮游亚系统中有３个功能群，底栖亚系统中有５个功能群。系统的能量来源为人工投饵和太阳光。研究分析两个亚系统中各个生物状态变量的公式表达及其在系统中的功能，阐明了能量在系统中的流动方向和公式表达。浮游亚系统与底栖亚系统通过ＰＯＣ的沉降过程以及营养盐在沉积物中的生物地化循环再生后，经由水／底界面进入水体而耦合。

| Abstract: | This paper describes a detailed structure of the prawn pond ecosystem. And a diagram of the energy flow of the system is presented. The prawn pond ecosystem is divided into two subsystems: the pelagic subsystem and the benthic subsystem. There are 3 functional groups in the pelagic subsystem, and 5 functional groups in the benthic subsystem. There are totally 8 biological state variables, and each is expressed by a differential function. Artificial food and irradiance are the two energy sourses of the ecosystem. The two subsystems are coupled by the process of POC sedimentation and the nutrient cycles of P, N and Si. |
