人类对河流氮输出的影响备受关注，因为氮输出的增加会显着提高初级生产力并降低沿海地区的水质。大多数这方面的研究都是针对中湿流域，而不是覆盖地球表面大部分的旱流域。本文使用河流数据来比较干旱地区和中湿地区的全流域氮输出以及人类对这种输出的影响。结果表明，虽然干旱流域的氮输出量低于中湿流域的氮输出量，但人类对酸形式氮输出的影响可能相似。在人口密度低的旱地和中水流域（
Human impact on export of nitrogen in rivers is of great concern because increases in nitrogen export can dramatically increase primary productivity and decrease water quality in the coastal zone. Most research on this has been done for mesic catchments and not the xeric catchments that cover a large fraction of the earths surface. This paper uses river data to compare whole-catchment nitrogen export from xeric and mesic areas and human impact on this export. Results suggest that although nitrogen export is lower from xeric catchments than from mesic catchments, human impact on export acid forms of nitrogen being exported may be similar. In both xeric and mesic catchments with low population density (
