【摘要】：近年来鄱阳湖秋冬季水文呈干枯态势,湿地生态系统及其关键因子也发生了变化。如何合理保护和利用鄱阳湖湿地引起各方关注。系统综述了鄱阳湖湿地生态系统在水文、江湖关系、水质、水鸟栖息地、渔业资源等方面存在的问题,梳理了引起这些问题的外部和内部因素。针对"一切照常"和"水位调控"两种情景,预测了湿地未来的变化趋势,并指出了当前研究中的不确定性问题。研究认为:鄱阳湖秋冬季的低枯水位,对水质、湿地植被、水鸟栖息地以及鱼类食物资源和"三场"(即:产卵场、洄游通道、索饵场)产生了一定不利影响。建议通过模型模拟和情景预测来分析不同调控方案的影响效果,优化调控方案、将生态系统的负面影响降到最低。
[Abstract]:In recent years, the hydrology of Poyang Lake in autumn and winter has been dry and the wetland ecosystem and its key factors have also changed. How to protect and utilize the wetland in Poyang Lake is concerned. The problems of the Poyang Lake wetland ecosystem in hydrology, river and lake relations, water quality, water bird habitat, fishery resources and so on are summarized. The external and internal factors that cause these problems. In view of the two scenarios of "all the usual" and "water level regulation", the trend of the change in the future of the wetland is predicted, and the uncertainty in the present study is pointed out. The study holds that the low water level in autumn and winter in Poyang Lake, the water quality, the wetland vegetation, the aquatic bird habitat, the fish food resources and the "three fields". (namely: the spawning field, migratory channel, cable bait field) has a certain adverse effect. It is suggested to analyze the effect of different control schemes through model simulation and scenario prediction, optimize the control scheme and minimize the negative effects of the ecosystem.
