Abstract

The effects of drainage and afforestation on the physical and chemical properties of soil in subtropical Sphagnum mire were explored to provide a theoretical basis for scientific protection and restoration of this type of wetland.Natural Sphagnum mire in Niangniang Mountain wetland,Guizhou was selected as the control site,and Cryptomeria fortunei forest formed by drainage for afforestation in the sphagnum mire with similar site conditions for 20 years was selected as the treatment site,and the differences in the physical and chemical properties of the surface (0~10cm) soil between the two kinds of sites were compared.Main results:1) The total soil carbon content,total nitrogen content,pH,mass ratio of carbon to phosphorus (C:P),mass ratio of nitrogen to phosphorus (N:P),available potassium content,nitrate nitrogen content,ammonium nitrogen content and soil mass water content of the Sphagnum mire were significantly higher than the corresponding index values of the Cryptomeria fortunei forest (P<0.05).The soil bulk density of Sphagnum mire was significantly lower than that of the Cryptomeria fortunei forest.2) PCA showed that the overall physical and chemical properties of the soil had changed significantly after the long-term afforestation of Cryphieria fortunea forest.3) Total soil carbon content was significantly positively correlated with total nitrogen content(P<0.01),and both of them were significantly positively correlated with C:P,N:P,available potassium content,nitrate nitrogen content,mass water content,respectively (P<0.01),and significantly negatively correlated with bulk density(P<0.01).C:P,N:P,ammonium nitrogen content,nitrate nitrogen content and available potassium content were very significantly or significantly positively correlated with each other.Mass water content was negatively correlated with bulk density(P<0.01).In conclusion,after a long-term afforestation of Cryptomeria fortuneana forest in Sphagnum mire,a large amount of organic matter in the surface soil oxidized and decomposed,soil water content decreased significantly,bulk density increased significantly,soil phosphorus limitation was relieved,and the soil physical and chemical properties were significantly different overall,and the peat soil was transformed into mineral soil.
