| 中文摘要 | Check dams have been widely used globally as human introduced structures for watershed management for various purposes. However, the effects of these structures for carbon retention have been scarcely considered and quantified. This research formulated a simple approach in estimating the carbon retention effects of check dams in Yan'an prefecture of the Loess Plateau region of China based on check dam inventory data and benefit transfer approach. Results indicated that the large and medium sized check dams had retained about 42.3 million tons of soil organic carbon (SOC) with a high spatial variability. This is a significant amount similar to about 1.48% of the SOC stored in the 0-40 cm soil layer across the whole Loess Plateau or roughly 4% of the estimated carbon emission from fossil fuel in China in 2000. Total volume of check dam is the most important influencing factor for carbon retention effects at both check dam and county-levels. Years after construction is also a significant factor at check dam level. The numbers of check dams and land use as well as topographical factors have impacts on the respect of check dam carbon retention of varied significance at the county-level. The effectiveness of carbon retention decreased from north to south. The results of this research can be used as important decision support for check dam development planning at the local context. This research also revealed the scientific worthiness in quantifying the carbon retention effects concerning the relationships between soil erosion and carbon cycling. On this respect, process-based monitoring and research are urgently in need. (C) 2012 Elsevier B.V. All rights reserved. |
