  • This paper takes marsh in the Sanjiang Plain as an example in order to research the effect of draining on the chemical elements in marsh. The Sanjiang Ecological Test Station of Mire and Uetland serves as the resarch base. The authors selected soil samples in the Sanjiang Plain (the top and the end of the drain, marsh soil and degeneration marsh soil), mainly analyzed contents of main ions (HCO3-, Cl-, SO42- and NO3- ), main heavy metals (Fe, Mn, Zn and Cu), nutritive elements (N, P, K), organic matter and pH value. By testing these samples as above, the paper initially researches the effect on chemical ele- ments content by draining by the means of the contrast of chemical elements contents between marsh soil and degenetative marsh soil and different characteristics of marsh soil elements. Results show that a lot of chemical elements had been lost because of draining.

THE EFFECT OF DRAINAGE ON CHEMICAL ELEMENTS CONTENT OF MARSH

Abstract: This paper takes marsh in the Sanjiang Plain as an example in order to research the effect of draining on the chemical elements in marsh. The Sanjiang Ecological Test Station of Mire and Uetland serves as the resarch base. The authors selected soil samples in the Sanjiang Plain (the top and the end of the drain, marsh soil and degeneration marsh soil), mainly analyzed contents of main ions (HCO3-, Cl-, SO42- and NO3- ), main heavy metals (Fe, Mn, Zn and Cu), nutritive elements (N, P, K), organic matter and pH value. By testing these samples as above, the paper initially researches the effect on chemical ele- ments content by draining by the means of the contrast of chemical elements contents between marsh soil and degenetative marsh soil and different characteristics of marsh soil elements. Results show that a lot of chemical elements had been lost because of draining.
