中文摘要： 近年来，池塘养殖业中普遍存在的环境污染、资源浪费、质量安全等问题日益突出，这些已严重制约了池塘养殖业的可持续发展，迫切需要整合其他技术来实现池塘养殖模式升级。人工湿地作为一种低成本的水处理设施，已被应用于水产养殖尾水处理。相比于其他渔业废水处理，人工湿地综合利用了生物能和天然能，具有构建成本低，能耗少，运行效果好，便于维护等优点。将人工湿地整合到池塘养殖，不仅实现了养殖废水的零排放，节约了水资源，同时也改善了池塘生态环境，保障了水产品的质与量。然而将人工湿地应用于池塘养殖进行水循环还处于定性阶段，缺乏定量研究。本次拟申请项目以人工湿地-池塘复合系统为对象，旨在通过系列试验揭示人工湿地净化养殖废水的动态过程与机理，同时在耦合湿地净化模型，池塘水质动态模型和鱼类生长模型基础上，提出系统适宜的配置参数和最佳的运作管理模式，从而为该复合模式的改进和推广应用提供技术支撑。

英文摘要： In recent years, there has been increasing popular problems related to environmental pollution, resource waste and product quality and safety across the industry of pond aquaculture. These problems have strictly restrained the sustainable development of pond aquaculture and therefore the need to upgrade the traditional culture model integrated with new technology is becoming essential. As a low-cost waste water treatment facility, constructed wetland (CW) has been gradually utilized in aquaculture. In comparison with other water treatment facilities, CW comprehensively uses the biological and solar energy in nature, hence possessing the advantages of low cost for construction, low energy consumption, high purifying performance and easy management. The integration of CW to pond aquaculture not only saves water resources by realizing zero discharge of aquaculture waste water, but also guarantees the quality and quantity of aquatic products via improving the eoc-environment of culture pond. However, studies on the application of CW to pond aquaculture are still in a qualitative stage, lack of systemic and quantitative investigations. The following project for application is concerned about a compound system consisting of CW and culture pond, aiming at revealing the dynamic process and mechanisms of aquaculture effl
