气候变化已被证明会增加自然灾害的发生并破坏生态系统。在沿海地区，从生物多样性的角度来看，有许多对环境具有重要意义的地区，例如根据《拉姆萨尔公约》登记的地区。钏路湿地是日本最大的湿地，也是日本最重要的自然系统之一，基本上未受到人类活动的影响。湿地里有许多不耐盐水的物种。当海平面上升时，由于钏路川沿岸的盐楔侵入范围扩大，淡水植物和鱼类群落可能会灭绝。因此，本研究尝试利用三维数值模型来了解海平面上升对湿地生态系统的影响，从而评估海平面上升对盐楔入侵的影响。据透露，当海平面上升约0.15米时，国家公园地区可能会受到咸水的影响。此外，海平面的最大上升可能会导致咸水入侵拉姆萨尔地区。因此，我们提出了保护湿地生态系统免受盐楔入侵的适应性管理策略。
Climate change has been revealed to increase the occurrence of natural disasters and to damage ecological systems. In coastal regions, there are many environmentally significant areas from the viewpoint of biodiversity, such as areas registered under the Ramsar Convention. The Kushiro Wetland is the largest wetland and one of the most significant natural systems in Japan, remaining mostly unaffected by human activity. In the wetland, there are many species, which do not tolerate saltwater. When the sea level rises, the communities of freshwater plants and fish may die out due to the extension of salt wedge intrusion along the Kushiro River. Therefore, in this study we make an attempt to understand the impact of sea level rise on the ecological system of the wetland by using a three-dimensional numerical model, which allows us to evaluate the effect of sea level rise on salt wedge intrusion. It is revealed that the National Park area may be affected by salt water when sea level rise reaches about 0.15 m. Also, the maximum sea level rise may induce saltwater intrusion into the Ramsar area. As a result, we proposed an adaptive management strategy for protecting the ecological system of the wetland from salt wedge intrusion.
