摘要
全球变暖是目前最重要的环境问题之一,将加速大气环流和水文循环过程,引起水文水资源及其空间分布的变化。长江三角洲是我国的经济核心区,1960年代以来区域气温上升,形成一个区域性热岛,1990年代以来增温幅度逐渐加大。在区域气候变暖的背景下,长江三角洲地区水文水资源特征发生趋势性变化,该研究从降水径流、海平面上升、海水入侵、水质污染4个方面,分析气候变化对长江三角洲地区水文、水资源变化趋势的影响。
Global warming has become one of important environmental issues,and will alter the spatial distribution of hydrology and water resources through accelerating atmospheric and hydrological cycles.Yangtze Delta region,an economic center in China,has experienced a regional temperature increase since the 1960s,forming a heat island,and the warming rate has improved since the 1990s.The characteristics of hydrology and water resources changed under regional climate warming.Here,the impacts of climate change on hydrology and water resources were discussed from the aspects of precipitation change,sea level rise,seawater invasion and water pollution in Yangtze Delta region,China.
