- 摘要:
- 研究了襄阳护城河水体中溶解氧的日变化特征，分析了襄阳护城河水体中影响溶解氧含量的因素。结果表明：襄阳护城河水中溶解氧含量的日变化特征是溶解氧的含量随光照强度的增加而逐渐上升；襄阳护城河水中消耗溶解氧的因素包括水生生物呼吸耗氧、有机物降解耗氧和底泥耗氧，其中底泥耗氧是水中溶解氧消耗的主要因素，占水体中溶解氧消耗的80%以上；护城河水体中溶解氧的增加因素包括空气表面复氧、水生植物和藻类的光合放氧，其中藻类光合放氧是水中溶解氧的主要来源，是表面复氧的10倍以上。试验结果对于水体中溶解氧的理论研究、水产养殖、水体的自净作用和护城河水的净化措施具有一定的价值。
- Abstract:
- The author studies the diurnal variation of dissolved oxygen in spring pond and analyses the correlative factors. Results show that the content of dissolved oxygen raises along with the radiation intensity, and achieves the maximum at about 16:30. The consumption of dissolved oxygen mainly included bio-consumption, degrading of organic compound and the consumption of sediment, of which the sediment consume above 80 percent of the dissolved oxygen consumption. The source of dissolved oxygen mainly include atmospheric respiration and phytoplankton photosynthesis, of which the latter is nearly above 90 percent of the dissolved oxygen source. The result provides some references to the research of dissolved oxygen in water body, aquiculture, self-purification of water body, and the purification of river.
