摘要
以土壤生态系统为基本单元,在对土壤有机碳、无机碳及相关资料调查分析的基础上结合GIS技术,对三工河流域土壤碳库进行了估算。结果表明三工河流域总碳储量约为11. 18Pg,其中有机碳占48. 54%,约为5. 43Pg,无机碳约占到51. 46%,约为5. 75Pg。
with soil ecosystem as basic unit, and on the bases of survey and analysis to soil organic carbon and soil inorganic carbon,Soil Carbon Reservoir in Sangong River Basin was evaluated with GIS technology.The result indicated the total carbon storage capacity in Sangong River Basin is 11.18 Pg, among which, the organic carbon content was (48.54%,)i.e. 5.43 Pg; Inorganic carbon content was 51.46%,i.e.5.75Pg.
