The long-term dynamic of the content and runoff of ammonia nitrogen in the water of the Middle Amur are discussed. There are decreasing of ammonia runoff in 1.4 times in comparison with 1981-2000, and dominance of nitrate nitrogen in runoff of mineral forms in recent years. Trends in runoff changes are due to transformation on the watershed. At present anthropogenic components of runoff is formed by the Songhua River runoff and is more pronounced in the wintertime.
