摘要
综合鄱阳湖国家级自然保护区内大湖池野外量测的和从中分辨率成像光谱仪(MODIS)影像反演得到的水体透明度信息分析其季节性变化规律,并探讨其与水位之间的关系。研究显示,大湖池水体透明度呈明显的季节性变化,即在春、晚秋和冬季透明度比较低,而在夏季比较高;大湖池水体透明度与水位具有显著的相关性。
Combining the water clarity recorded in the field with that derived from Moderate Resolution Imaging Spectroradiometer （MODIS） images, the seasonal dynamics of water clarity were analyzed and their relation with the water level was also explored in Lake Dahuchi within the Poyang Lake National Nature Reserve, in China. The results demonstrated an apparent seasonal pattern of water clarity in Dahuchi. Water clarity was lower in the spring, later in autumn and winter, and higher in summer when it correlated significantly with the water level.
