海水水族箱生态系统的构建及运行稳定性

通过构建海水水族箱,分析其内过滤、温控等系统的构建模式,为研究人工生态系统中浮游生物、大型海藻、鱼类等生物的优化配置、生长模式和景观效果评价提供依据。根据水族市场调研结果进行系统内动植物配置,主要动物数量比为清洁虾∶珊瑚=5∶1,大型海藻体积比为红藻门∶绿藻门∶褐藻门=7∶5∶3;为期一年的实验期间系统水质监测结果表明,稳定期水体硬度平均为5 159 mg/L,TN和TP分别为28.38μmol/L和6.09μmol/L,达到海水水质Ⅱ类标准,适合海水养殖;构建生态系统稳定性评价指标体系评价系统运行效果,R=8.54系统稳定性介于中度和高度稳定之间,生物多样性是其稳定性的决定因素。稳定的海水养殖系统可减少维护时间和费用,为动植物繁育研究提供实验场所,实现科研、经济、稳定、美观等多重效果,系统构建和模式开发为"经济—生态—人文"生活理念的认同和推广提供了客观理论依据。

The construction and running stability of the ecological system in seawater aquarium

In order to provided building sites of biological collocation and landscape effect for plankton, large algae, fish and others＇ optimal growth model, we analysed the building model of aquatic animals in filtration and temperature control system through the establishment of aquarium. According to the aquarium market research, the animal and plant configuration in system is as follows. The clean shrimps and coral is 5： 1, Rhodophyta, Chlorophyta and Phaeophyta is 7： 5： 3. The water quality monitoring result showed that the water hardness, TN and TP were maintains at 5 159 mg/L, 28. 38 μmol/L and 6. 09 μmol/L during stable phase respectively . The water quality was reached to the second class of the water standard, which is suitable for mariculture. It is the construction of the evaluation index system of ecological system stability that to evaluate the system＇ s running efficacy. While the result shows that R = 8. 54, the system is between intermediate and high stability, and biodiversity in the ecological system is the determinant factor. A stable maricuhure system is time-saving and cost-saving, providing places for animal and plant breeding research and achiveing the multiple effects, such as being scientific, economic, stable, beautiful, etc. The construction of the system model also provides theoretical basis for the ＂economy-ecological-humanities＂ life philosophy.
