1. As a result of sea‐level rise (SLR), coastal anchialine pool habitats will be lost in some locations and will expand inland into low‐lying areas in others. New and existing habitats may risk additional SLR‐related degradation from non‐native species transmission, groundwater pollution, and increased contact with human infrastructure. Despite a worldwide distribution, anchialine ecosystems and biota have been largely omitted from SLR risk assessments for coastal ecosystems.
2. Anchialine pools and caves are composed of brackish groundwater that connects to the marine environment through porous rocky substrate but have no overland connection to the ocean. They support unique endemic biota.
3. The goal of this study was to develop methods to assess potential impacts to anchialine pools from future coastal flooding, using the island of Hawai'i as a case study. Flood predictions incorporated pool surveys, groundwater‐level measurements, and statistical analysis of flood frequencies observed in tide gauges combined with regional scenario‐based projections of future sea levels. High‐resolution geospatial models were then generated to predict anchialine pool location, density, and risk factors for the next 60 years.
4. Along 40 km of coastline, up to 80% of current anchialine pools will be lost by 2080 as pools merge with ocean habitats; however, as groundwater flooding occurs more frequently and new habitats are created inland, the total pool counts will rise from 509 in 2018 to 1,000 by 2080. As a result of extreme water‐level events, non‐native fishes are predicted to disperse into 42% of pools by 2030. Based on current conditions, development and cesspool risks are quite low for anchialine pools in the study area.
5. Outcomes from this study are guiding conservation actions, including habitat restoration, non‐native fish removal, and development planning decisions in coastal areas. This study illustrates methods that can be used to assess the effects of SLR on anchialine pool habitats worldwide.

评估地下水养育的chi胺生态系统对海平面上升的时空响应，以进行沿海地区管理

1. 由于海平面上升（SLR），沿海an鱼碱池栖息地将在某些地方消失，并将在内陆扩展到其他地方的低洼地区。非本地物种传播，地下水污染以及与人类基础设施的接触增加，新的和现有的栖息地都可能面临与SLR相关的其他退化的风险。尽管分布在世界各地，但沿海岸带生态系统的SLR风险评估在很大程度上省略了an碱生态系统和生物区系。
2. chi鱼池和洞穴由微咸的地下水组成，这些咸水通过多孔的岩石底物连接到海洋环境，但没有与海洋的陆上连接。他们支持独特的地方生物群系。
3. 这项研究的目的是开发一个方法，以夏威夷岛为例，评估未来沿海洪水对邻苯二甲酰胺池的潜在影响。洪水预报结合了水池调查，地下水位测量以及潮汐计中洪水频率的统计分析，并结合了基于区域情景的未来海平面预测。然后生成高分辨率的地理空间模型，以预测未来60年的chi碱池位置，密度和风险因素。
4. 沿着海岸线40公里，到2080年，随着池与海洋生境的融合，目前将失去80％的现有邻氨基苯甲酸池。但是，随着地下水泛滥的发生和内陆地区新栖息地的建立，到2080年池总数将从2018年的509增加到1000。由于极端水位事件的发生，预计非本地鱼类将扩散到42种鱼类中。到2030年占池的百分比。根据当前情况，研究区域中的chi鱼碱池的开发和污水池风险非常低。
5. 这项研究的结果指导了保护行动，包括栖息地的恢复，非本地鱼类的去除以及沿海地区的发展规划决策。这项研究说明了可用于评估SLR对全世界an鱼碱池栖息地的影响的方法。
