鄱阳湖水体淹没模型研究
STUDY OF WATER FLOODING MODEL OF POYANG LAKE BASED ON BASIN PRECIPITATION
-
摘要: 根据丰水季鄱阳湖流域降水对鄱阳湖水位的影响研究, 建立鄱阳湖水位变化降水预测模型;并利用近10年卫星遥感对鄱阳湖水域面积的监测及相应时相鄱阳湖水位资料的分析, 研究出丰水季鄱阳湖水体淹没模型, 解决了洪水季, 云天状况下, 气象卫星难以监测下垫面洪涝灾害的难题。通过对鄱阳湖水体淹没模型进行模拟验证, 结果表明, 鄱阳湖实施退田还湖以后, 湖体水面模拟结果与遥感测算值相对误差为0.9%～3.6%, 模拟效果好。Abstract: Based on the study of the precipitation of water systems impacting on water level of Poyang Lake in some water seasons, a forecast model of water level changing with precipitation is developed. Using the analysis results of water area of remote sensing monitoring and water level of Poyang Lake in the same time in lately ten years, the water flooding model of Poyang Lake much water season is studied. And solved a trouble that meteorological satellites can not monitor the water area in water flooding time in cloudy weather. Through checking up the modeling results, it is proved that the modeling effects are good after quitting cultivation and resuming lake in Poyang Lake area, the relative difference between modeling value and remote sensing monitoring data are from 0.9 to 3.6 percent.
