Title: Dissolved Organic Carbon and Nitrogen in Different Mixed Forest Stands in Saline Land of Yellow River Delta
Abstract:The contents of soil dissolved organic carbon(DOC)in Robinia pseudoacacia,Robinia pseudoacacia+Fraxinus chinensis mixed forest,Robinia pseudoacacia+Ulmus pumila mixed forest,and Robinia pseudoacacia+A...The contents of soil dissolved organic carbon(DOC)in Robinia pseudoacacia,Robinia pseudoacacia+Fraxinus chinensis mixed forest,Robinia pseudoacacia+Ulmus pumila mixed forest,and Robinia pseudoacacia+Ailanthus altissima mixed forest in saline land of the Yellow River Delta were studied.Among the four forest patterns,the DOC and dissolved organic N(TSN)in soil humus had significantly higher contents than those in the 0—20and 20—40cm soil layers,and the highest content of the DOC was founded in Robinia pseudoacacia + Ailanthus altissima mixed forest(257.70 mg/kg).In addition,the contents of total N(TN)and the TSN in Robiniapseudoacacia + Ailanthus altissima mixed forest were1 065.79and 55.80mg/kg,respectively.Soil contents of the DOC and TSN in the four forest patterns were showed as the order of Robinia pseudoacacia+Ulmus pumila Robinia pseudoacacia+Ailanthus altissima standRobinia pseudoacaciastandRobinia pseudoacacia+Fraxinus chinensis.The DOC and TSN were significantly correlated with TN,available P,available K and salinity.Read More
