【摘要】：近年來鄱陽湖秋冬季水文呈干枯態(tài)勢,濕地生態(tài)系統(tǒng)及其關(guān)鍵因子也發(fā)生了變化。如何合理保護和利用鄱陽湖濕地引起各方關(guān)注。系統(tǒng)綜述了鄱陽湖濕地生態(tài)系統(tǒng)在水文、江湖關(guān)系、水質(zhì)、水鳥棲息地、漁業(yè)資源等方面存在的問題,梳理了引起這些問題的外部和內(nèi)部因素。針對"一切照常"和"水位調(diào)控"兩種情景,預測了濕地未來的變化趨勢,并指出了當前研究中的不確定性問題。研究認為:鄱陽湖秋冬季的低枯水位,對水質(zhì)、濕地植被、水鳥棲息地以及魚類食物資源和"三場"(即:產(chǎn)卵場、洄游通道、索餌場)產(chǎn)生了一定不利影響。建議通過模型模擬和情景預測來分析不同調(diào)控方案的影響效果,優(yōu)化調(diào)控方案、將生態(tài)系統(tǒng)的負面影響降到最低。
[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.
