| 摘 要： | 利用2005年4月至2010年5月湖口水位资料和新一代极轨卫星( Terra)遥感的鄱阳湖水域面积资料,研究发现它们已经不满足原有鄱阳湖水域面积与湖口水位的关系模型(基于NOAA遥感资料).运用最小二乘法和多项式拟合方法,综合考虑模拟与Terra卫星遥感的鄱阳湖水域面积的均方差和湖口极端水位下的拟合情况,发现在1-10...

| Abstract: | In this paper,water level data of Hukou and Terra satellite remote sensing data are investigated,and it is found that these data did not meet with those from the old model derived from water level data at Hukou and satellite remote sensed by NOAA.Based on the methods of least square and polynomial fitting,a new relation model which can simulate effectively the water coving of Poyang Lake is built and the related coefficient is 0.982.Finally,the Terra satellite data and Hukou water level data from January to October,2011 are used to validate the new model. |
