秸秆还田等农田管理措施能有效地增加土壤碳储量,从而有利于减缓大气CO_2浓度的上升趋势。论文基于环境政策综合气候模型(EPIC),采用千烟洲生态试验站和鹰潭生态试验站农田监测场长期观测数据,验证和优化了EPIC模型参数,同时利用1990—2010年江西省气象资料以及土壤清查资料,模拟分析了4种秸秆还田(CR)比例情景下2010—2030年江西省水稻田土壤的固碳潜力。研究结果表明,无秸秆还田(CR0%)和秸秆还田25%(CR25%)两种处理下耕作层土壤有机碳储量分别下降21.3%和6.5%,秸秆还田50%(CR50%)和100%(CR100%)处理下土壤有机碳储量分别增加5.4%和11.9%;相对CR0%情景而言,CR25%、CR50%、CR100%情景下江西省水...

Straw return and other farming management measures can effectively increase soil or ganic carbon （SOC） storage, thus contributing to mitigate the increase in the atmospheric CO2 concentration. Based on the EPIC model, which was validated using the database of longterm ob servation in Qianyanzhou and Yingtan experimental stations in Jiangxi Province. EPIC model was based on the meteorological information from 1990 to 2010 and soil database in Jiangxi Province, to simulate the paddy soil carbon sequestration potential from 2010 to 2030 under al...
