淮河流域周村水库夏季CDOM吸收光谱特征、空间分布及其来源分析∗
Summer absorption characteristics, spatial distribution and source analysis of CDOM in Zhoucun Reservoir in Huaihe Catchment
摘要
Abstract
Based on the data of the absorption coefficient of colored dissolved organic matter (CDOM) from 24 surface water sam-ples collected from Zhoucun Reservoir in Huaihe Catchment, we analyzed the spatial distribution characteristics of CDOM absorp-tion coefficient, investigated the correlation between CDOM absorption coefficient and environmental parameters, and explored the possible source of CDOM in the reservoir. The samples collected from the reservoir were categorized into three different groups (storage port, transition region and main reservoir area), the absorption coefficients ( a(355) and a∗(355)) had a decrease process from the storage port to main reservoir area, while the S value exhibited an increased trend. Meanwhile, significantly nega-tive correlations of the value of S240-500 were found with a(355) and a∗(355), respectively, which may have implications for the remote sensing estimation of CDOM in this study. A significantly negative correlation between a(355) and dissolved organic carbon (DOC) concentration was conducive to the establishment of DOC remote sensing inversion model, and relationships between a (355) and aph(440) implied the potential contribution of phytoplankton metabolism and degradation products to the CDOM pool in the Zhoucun Reservoir. These results on the CDOM analysis made a significant contribution to the management of the Reservoir in the future.关键词
