海河流域土壤中碳的库存与通量研究

THE STORAGE AND FLUXES OF CARBON IN SOIL OF HAIHE RIVER BASIN

通过对海河流域土壤中碳及其各形态含量的分析结果．计算出该流域土壤中碳的库存量为１．７７×１０￣（１２）ｋｇ．并以成土母质、人畜粪、化肥施入和径流带入量、大气降尘及其植物的残留等因素为对土壤中碳的贡献；同时以径流的带出、大气扬尘及植物体的茎叶等因素为碳的迁出部分，计算出海河流域土体中碳的进出量分别为４．３９×ｌ０￣（１０）ｋｇ／ａ和４．０９×１０￣（１０）ｋｇ／ａ，并研究其流通关系．

The storage of carbon in soil of Haihe River basin is l.77×l0￣(12)kg calcu-lated according to the analytical result.The total input of carbon from pa-rental material,the excrement of human body and other living things,ap-plication of chemical fertilizer,and inflow through run-off,air deposit,and plant residue is 4.39×l0￣(10)kg/a. The output of carbon is 4.09×l0￣(10)K/a,through run-off,dust-raising,and uptake by plant.
