摘　　要：轮换式地于枯水期在鱼卡河冲洪积扇开采1.87×10~4m^3／d的地下水、丰水期在鱼卡河大桥上游取用1.87×10~4m^3／d的地表水,对马海盆地水资源的影响很小,但有可能引起开采区附近和下游马海盆地局部地区地下水位下降、局部泄出带流量减少、部分地段沼泽湿地轻微退化等与水资源有关的生态环境问题。当地下水位下降到“临界深度”以下时,有利于马海盆地土壤盐渍化不治自愈。The rotational exploitation of 1.87×10^4 m^3/d of grotmdwater in the alluvial-diluvial fan of the Iqe River in the low-water season and drafting of 1.87×10^4 m^3/d of surface water from the upstream of the Iqe River Bridge in the high-water season has little influence on the water resources of the Mahai basin but is likely to cause eco-environmental problems related to water resources, such as the local drop of the groundwater level, decrease of flow in local discharge zones and slight degradation of swamp wetland in some places near the exploitation area and the Mahai basin in the lower reaches of the river. When the groundwater level drops below the ＂critical depth＂, the salinized soils in the Mahai basin will be desalinized without treatment.
