摘要
阐述影响池塘养殖水体溶解氧的主要因素,主要包括浮游藻类的光合作用、空气扩散作用、水体呼吸作用和底质呼吸作用。分析透明度与池塘上下层水体溶解氧水平的关系以及空气扩散进入水体的影响因素。水体呼吸作用即水体中浮游生物、细菌呼吸消耗氧气是溶解氧消耗的主要去向。详细分析池塘底泥层次以及底泥对池塘中溶解氧浓度和水质的影响。
The factors which influenced the dissolved oxygen in aquacultural ponds were disscussed.The factors included photothenthesis of phytoplankton,reaeration,water column respiration,and sediment oxygen demand.The relationship between secchi disk visibility and the dissolved oxygen in aquacultural pond was analyzed.The water column respiration was the main consumer of O2.The profile of the aquacultural pond＇s sediment was described in detail,and the condition of sediment had impacts on the water＇s quality and DO.
