Multi-scale spatial determinants of dissolved oxygen and nutrients in Qiantang River, China

摘要: This study employed spatial regression to analyze the determinants of dissolved oxygen (DO) and nutrients in Qiantang River, China. Determinants their patterns 1996 2003 as well dynamics during this time period were characterized at sub-basin 500-m riparian buffer scales. Results indicated that differed by variable scale. Built-ups, farmland, water body, population density gross domestic product positive indicators for nutrient pollution hypoxia, while distance river source forest negative indicators. Higher slope variability indicates more DO nutrients. In addition, built-up increases accelerated growth economic development accounted a large extent. highlighted incorporation autocorrelation into was not only methodological advantage but also promising management tool.
