【摘要】：由于国内对海水中有机质耗氧过程的观测,大多局限于实验室模拟培养实验,尚缺乏进行现场培养实验的手段.为此,自主研发了一种海底水体溶解氧消耗过程原位培养装置.该装置集成了包括电子控制模块、电机、培养容器与海水测量传感器等在内的电控处理模块和机械结构框架于一体,并讨论了其电控处理模块的详细设计,给出了实物样机在象山港海域所进行的性能测试结果.结果表明:设计的现场培养装置具备对海底水体的溶解氧耗氧过程进行现场培养和观测的功能,对于国内开展底层水体缺氧区观测和了解当地生态环境状况具有重要意义.
[Abstract]:Due to the observation of oxygen consumption of organic matter in seawater, mostly confined to the laboratory incubation experiment, field culture experiment means is still lacking. Therefore, independent research and development of a bottom water dissolved oxygen consumption in situ cultivation device. The device includes an integrated electronic control module, motor, and measurement of seawater culture vessel sensor, electronic control module and the mechanical structure in one, and discusses the detailed design of electronic control module, and give the results of performance test of physical prototype in Xiangshan harbor. The results show that the design of the site training device with dissolved oxygen on the bottom water oxygen consumption process on-site training and observation function, is of great significance to the local ecological environment observation and understanding of the bottom water Hypoxia Zone to carry out domestic.

【正文快照】： 近几十年,长江流域伴随其经济快速发展的同时,江水所携带的各类营养盐浓度也上升了几十倍,这使得长江口海域的富营养化程度越来越严重.水体富营养化改变了本海域生产力的结构,导致赤潮频繁且大面积的爆发,继而引起夏季底层水体缺氧现象的常态化出现,对我国东海渔业造成了威胁[
