本发明公开了种海岛湿地生态保水方法，包括如下步骤：步骤、在径流沟的下游沟口处修建保水坝，保水坝的顶部间隔设有多个凹陷的泄水口；步骤二、修整径流沟，并在其两侧的湿地上挖掘多个蓄水池，蓄水池与径流沟之间以及蓄水池与蓄水池之间均通过连接沟连通；步骤三、在径流沟、蓄水池和连接沟的明水面上种植水生植物，使其覆盖度达60-80％，在海岛湿地的边坡和积水坡面上种植陆生耐盐植物，使其郁闭度在0.8以上；步骤四、向蓄水池中投放水生生物。本发明可增加海岛湿地蓄水量2-8倍，截流9-37％的径流量，减少蓄水量47％的蒸发消耗，大大减少了淡水资源的浪费。 The invention discloses an ecological water conservation method for a sea island wet land. The ecological water conservation method comprises the following steps that I, a water conservation dam is built at a downstream ditch opening of a runoff ditch, and a plurality of concave drain openings are formed in the top of the water conservation damp at intervals; II, the runoff ditch is trimmed, a plurality of reservoirs are excavated in the positions, located at the two sides of the runoff ditch, of the wet land, the reservoirs communicate with the runoff ditch through connecting ditches, and the reservoirs communicate with one another through connecting ditches; III, aquatic plants are planted on the surface of open water in the runoff ditch, the
