Spatial distribution characteristics and ecological effects of carbon and nitrogen of soil in Huolin River catchment wetland

Abstract

Abstract: This paper studied the spatial distribution characteristics and ecological effects of organic carbon and nitrogen in soils of Huolin River catchment wetland in horizontal and vertical levels.The results showed that the differences of horizontal and vertical distribution of organic carbon and nitrogen were very obvious, and of all the factors such as the period of wetting and drying cycles, leaching, plant and flood etc.,the period of wetting and drying cycles was contents the critical one, which caused the differences.Soil organic carbon was significantly correlated with soil nitrogen (r=0.977).The ratio of carbon and nitrogen (C/N) changed along with the humidity gradient, and soil pH values obviously influenced the concentration of organic carbon and nitrogen.The correlation of C/N values and organic carbon and nitrogen contents in wetland soil and in grassland soil were remarkably different, and the ecological effects mainly included production effect and clarification effect.

Key words: Huolin River catchment wetland Soil organic carbon, Total nitrogen, Spatial distribution characteristics, Ecological effect
