这研究的目的是调查在实验室在巨大的海蜇的分解的过程释放并且发现了证据验证海蜇的分解在这个领域里在生态系统上释放的营养素的影响的氮和磷。从 Nemopilema nomurai 的分解的氮和磷的版本在象不同 pH 价值，咸度价值，温度和氮和磷集中那样的不同孵化条件下面在一系列实验被检验。结果证明 Nemopilema nomurai 的完全的分解通常拿了大约 48 d。从 Nemopilema nomurai 的分解的氮和磷的版本能被划分成二个阶段：早阶段和以后的阶段，尽管氮的流出率非常是一份订单磷。在 Nemopilema nomurai 的分解的早阶段，在很快增加的海水的溶解的氮，溶解的磷，全部的氮和全部的磷的集中，和氮的集中能在整个降级过程到达高水平。在分解的以后的阶段，溶解的氮和全部的氮的集中慢慢地衰退了，当水里的磷的集中能在降级过程到达最大值时。高 pH，低咸度，高温度和 N/P 将支持氮的版本；低 pH 对氮的版本相反但是对磷的版本有利。另外，我们发现底部水里的铵和磷酸盐的集中在在 Jiaozhou 海湾的海蜇花蕾的经期期间比表面水里的那些高，证明海蜇的分解释放的营养素有对这块地里的氮和磷的重要影响。为整个黄海，海蜇尸体释放的营养素可以到达直到(2.63

英文摘要：

The aim of this study was to investigate nitrogen and phosphorus released in the process of the decomposition of giant jellyfish in the laboratory and found the evidence to verify the influence of nutrients released by the decomposition of jellyfish on the ecosystem in the field. The release of nitrogen and phosphorus from the decomposition of Nernopilerna nomurai was examined in a series of experiments under different incubation conditions such as different pH values, salinity values, temperatures and nitrogen and phosphorus concentrations. The results showed that the complete decomposition of Nemopilema nomurai generally took about 4-8 d. The release of nitrogen and phosphorus from the decomposition of Nemopilema nomurai could be divided into two stages： the early stage and the later stage, although the efflux rate of nitrogen was one order more than phosphorus. In the early stage of the decomposition of Nemopilema nomurai, the concentrations of dissolved nitrogen, dissolved phosphorus, total nitrogen and total phosphorus in seawater increased rapidly, and the concentration of nitrogen could reach the highest level in the whole degradation process. In the later stage of the decomposition, the concentrations of dissolved nitrogen and total nitrogen declined slowly, while the concentration of phosphorus in water could reach a maximum in the degradation process. High pH, low salinity, high temperature and N/P will promote the release of nitrogen; low pH is unfavorable to the release of nitrogen but favorable to the release of phosphorus. In addition, we found the concentrations of ammonium and phosphate in the bottom water were higher than those in the surface water during the period of jellyfish bloom in the ]iaozhou Bay, proving that nutrients released by the decomposition of jellyfish have significant influence on nitrogen and phosphorus in the field. For the whole Yellow Sea, nutrients released by jellyfish carcasses may reach up to （2.63±2.98）x10^7 mol/d of dissolved nitrogen （DN） and （0.74±0.84
