以月数据为基础，综合考虑3个相邻浅水咸淡湖的入水量、含盐量和磷储量的变化以及入磷负荷，计算了3个相邻浅水咸淡湖的原位磷释放速率。根据1993年1月至2002年12月的10年估算，3个水体的年沉积磷与入流磷的比值各不相同：真尻湖为16%，本荘湖为3%，中海湖为- 8%。在暖季，这三个水体的磷释放量都超过了沉淀量。中umi湖的年沉降比低，除了与较大的海水回流导致的除磷作用有关外，还与稳定的分层结构有关，由于下层缺氧，促使沉积物中磷释放。在中见湖，当沉积物表面溶解氧低于2.54 mg L−1时，沉积物中磷的释放开始加速。
In situ phosphorus release rates in three contiguous shallow brackish lakes were calculated by considering the amount of water inflow, changes in salinity and phosphorus stock, and loading from phosphorus inflow based on monthly data. The annual amount of sedimental phosphorus relative to that of phosphorus inflow was different for each of the three water bodies: 16% for Lake Shinji, 3% for the Honjo area, and −8% for Lake Nakaumi, as estimated in a 10-year period from January 1993 to December 2002. During the warm season, the quantity of phosphorus released surpassed sedimentation in these three water bodies. The low annual sedimentation ratio in Lake Nakaumi is related to a large seawater backflow resulting in phosphorus removal, in addition to a stable stratified structure promoting phosphorus release from sediment due to oxygen depletion in the lower layer. In Lake Nakaumi, field data shows that if dissolved oxygen at the sediment surface falls below 2.54 mg L−1, phosphorus release from the sediment begins to be accelerated.
