我国正处于城市化快速发展阶段，城市化进程导致了不透水地表（impervioussurfacearea，ISA）的增加，河流湖泊等地表水水质退化。本研究选取城市化进程较快，涉及区域饮用水安全的东南沿海流域—九龙江流域为代表性流域，采用遥感、GIS、现场监测和统计分析相结合的方法，基于归一差值不透水面指数法（NDISI，normalizeddifferenceimpervioussurfaceindex）和线性光谱混合模型（LSMM，linearspectralmixturemodel）提取2007年和2010年的九龙江全流域和城市小流域ISA，开展17个典型子流域和2个城市小流域水质现场监测，并...China is at a stage of rapid development of urbanization. Impervious surface area (ISA) increased, accompanied with accelerating urbanization, thereby making the water quality in the receiving water bodies like rivers and lakes degraded. .Remote Sensing, Geographic Information System, in-situ monitoring, and multivariate analysis were coupled in this study to explore the ISA dynamics and its water...学位：理学硕士院系专业：海洋与环境学院环境科学与工程系_环境管理学号：2262009115118
