摘要
系统研究鄱阳湖洲滩湿地大气-植被-土壤-地下水系统生态水文过程对于鄱阳湖湿地植被生态系统的保护具有重要意义。以修水和蚌湖之间的洲滩为研究对象,通过耦合降水截留、蒸散发、植被根系吸水、土壤水运动和地下水运动模块,构建了鄱阳湖典型洲滩湿地生态水文模型,并对蒸散发、土壤湿度和地下水位变化过程进行模拟。研究结果表明,模拟结果能较好地反映鄱阳湖典型洲滩湿地的生态水文特征,研究成果能够为鄱阳湖典型洲滩湿地生态水文模型研究提供理论参考。
Systematic study of the eco-hydrological process in atmosphere-vegetation-soil-groundwater system is of great significance for the protection of vegetation ecosystem of Poyang Lake wetland.In this paper,the eco-hydrological model for typical wetland of beach in Poyang Lake is constructed by coupling the precipitation interception,evapotranspiration,water absorption by vegetation root,soil water movement and groundwater movement.Then the variation of evapotranspiration,soil moisture and groundwater level was experimentally simulated.The results show that the model can reflect the eco-hydrological characteristics of the typical wetland of beach in Poyang Lake.This paper can provide theoretical support for the systematic study of the eco-hydrological process in typical wetland of beach in Poyang Lake.
