基于弹性指数的河流水质对气候弹性的响应特征研究
发布时间：2021-11-01 17:40
本文旨在系统探讨河流水质对降水、气温变化及非气候因素响应的敏感性。论文采用微观经济学的弹性原理（需求的价格弹性）进行敏感性分析来揭示气候因子与水质的定量关系。在此基础上,基于双变量和多元统计法提出水质气候弹性概念（CEWQ）,以确定全球范围内主要水质参数的敏感性。主要创新之处为在全球尺度上的研究引入弹性方法,解决了基于过程的水质水文模型难以进行大尺度研究的困境。对大量的水质气候弹性值的观察表明,该方法在描述全球范围内的水质对气候变化的响应程度是有用的,而不是简单的统计相关性。由于站点特异性,与温度弹性相比降水弹性在空间中是高度变化的。降水弹性显示出显著的季节性。简单地说,这项技术在全球范围内揭示了水质参数应对气候驱动因子变化过程。此外,总氮和水温对空气温度的响应是显著的。特别的,在育空河和墨累河流域,除了浑浊度和过滤的硝酸盐及亚硝酸盐外,其他主要水质参数呈下降趋势,而湄公河大多数的水质参数呈上升趋势。相比育空河和墨累河两大流域（除了过滤的硝酸盐亚硝酸盐以及未过滤的总氮）,湄公河主要水质参数和对应百分比变化有长尾分布特征。湄公河流域和墨累河流域的降水弹性结果具有统计显著性,育空流域的温度...
