摘　　要：目的建成受控生态生保技术综合实验系统,为下一步开展受控生态生保系统的整合实验和系统内物质闭合循环实验研究构建试验平台。方法在大量方案调研、方案设计和图纸设计的基础之上,通过加工、安装和联合调试等技术手段来实现。结果该系统容积约为40m3,其舱内温度、相对湿度、氧浓度、二氧化碳浓度、总压、光照强度、光照周期、栽培基质水分含量和乙烯浓度等参数均得到有效控制,系统运行稳定;栽培系统包括左右两排,每排分为上下两层;栽培床总面积约为8.4m2,其上下垂直距离电动可调;光源为红色和蓝色两种发光二极管的组合。结论该试验平台的成功研制,为下一步开展大规模受控生态生保技术整合试验研究创造了必备条件。Objective To develop a complex experimental system as a test platform for further integrated experiments and material close-loop experiments of the controlled ecological life support system（CELSS）. Method Basing on a large amount of plan investigations, plan designs and drawing designs, the system was built through the steps of processing, installation and joined debugging. Result The system comprises a cabin with the volume of about 40 m^3 ; its interior atmospheric parameters such as temperature, relative humidity, oxygen concentration, carbon dioxide concentration, total pressure, lighting intensity, photoperiod, water content in the growing-matrix and ethylene concentration were all monitored and controlled automatically and effectively, and remained good stability. The growing system consists of two rows of racks along its left-and-right sides separately , and either of which has supper and lower layers;eight growing beds hold a total area of about 8.4 m^3, and the vertical distance between the two layers can be adjusted automatically and independently; lighting sources consist of a combination of red and blue light-emitting diodes. Conclusion The system provides essential conditions for future large-scale integrated studies of controlled ecological life support techniques.
