A summary of the scientific literature on the effects of fire on the concentration of nutrients in surface waters

摘要: Abstract : This paper provides a detailed review of the chemical changes that occur in soil during fire, pathways by which nutrients are transferred from to surface-water bodies following and temporal spatial effects fires on concentration fire have been reported scientific literature. Thirty-nine papers literature represent studies (1) were done variety environments (savannas, grasslands, temperate forests, alpine so forth); (2) had range sampling frequency duration, such as immediately (from start 1 year later), short-term end 3 years long term-sampling (sampling for greater than fire); (3) incorporated watersheds with various burn intensities, severities, histories reviewed summarized. The has revealed measurable streamwater quality most likely if was severe enough large amounts organic matter, windy conditions present heavy rain occurred watershed steep slopes soils little cation-exchange capacity. Measurable lake- reservoir water if, addition factors listed streams, lake or is oligotrophic mesotrophic residence time short relative length elevated concentrations runoff. Knowledge whether nitrogen phosphorus limited important because eutrophication nitrogen-limited lakes may due increasing nitrogen:phosphorus ratios.
