摘要: 在全球气候变化和人类活动影响下,辽宁省双台子河口湿地出现生态用水不足,水环境恶化,土壤盐渍化和海水倒灌等问题,导致湿地明显退化。为解决湿地生态用水供需矛盾,从流域生态水文学角度出发,运用所构建的生态水文耦合模型,对1981~2005年双台子河口湿地集水区生态水文演变规律进行模拟,结果表明:25年间湿地集水区各生态水文要素年际变化均呈减少趋势,但减小范围并不明显;年内变化呈单峰曲线,主要集中在7月和8月。丰水年天然补水量为8.32亿m3/a,基本可以满足生态需水要求;平水年为6.21亿m3/a,尚可满足湿地最小区的最低生态需水要求;枯水年为4.70亿m3/a,生态缺水严重,生态补给量为1.15~3.90亿m3/a,需采取相应调控措施,以满足湿地生态需水要求。

Abstract: Due to the impact of global climate change and human activities, there are some problems such as ecological water scarcity, water quality degradation, soil salinization, seawater intrusion and so on, resulting in area reduction of Shuangtaizi estuarine wetland. To restore and protect the wetland environment and address the balance of water supply and demand in wetland, this paper used the eco-hydrological coupling model in the eco-hydrological viewpoint, and simulated eco-hydrological processes of Shuangtaizi estuarine wetland from 1981 to 2005. The results showed that: the inter-annual change of the hydrological elements in the wetland showed a decreasing trend, but the reduced coverage was not significant; the annual change showed a single peak curve, mainly in July and August. The natural supplement water was 8.32 billion cubic meters per year in the wet year, which can meet the eco-water demand. The natural supplement water was 6.21 billion cubic meters per year in normal year, which can meet the minimum eco-water demand. Eco-supply capacity was 1.15—3.90 billion cubic meters per year in the low flow year with the natural supplement water being 4.70 billion cubic meters per year. The eco-water demand can be met after the appropriate measures for ecological supplement regulation are taken.
