碳汇估算方法研究进展

从森林碳汇估算方法、林下-土壤碳汇估算方法、土壤碳汇估算方法、岩石-流域碳汇估算方法和海洋碳汇估算方法5个方面综述近年来国内外学者对于碳汇估算方法的研究现状.认为目前碳汇估算方法研究中还存在基础理论仍落后于实践、碳汇估算结果存在较大的差异、碳汇模型不够精确、基础数据的采集工作欠缺和岩石圈碳汇研究有待深入等不足,建议从建...

Progress of Research and Prospect on Evaluation Methods of Carbon Sink

Based on the progress in research on five aspects of evaluation methods of carbon sink studied by both home and abroad scholars in recent years,including evaluation methods of forest carbon sink,evaluation methods of subjacent forest-soil,evaluation methods of soil,evaluation methods of rock-watershed and evaluation methods of sea,the paper points out that five deficiencies exist in the current research,such as the lag of the basic theory behind the practice,big difference in evaluation results of carbon sink,existing issues on evaluation results from carbon sink models,lack of basic data collection and lack of research on carbon sink in lithosphere.Three aspects of future research are proposed,including establishing large scale carbon sink information system,improving spatial sampling methods and accuracy,and promoting the application of radioactive carbon isotope(14C).
