中文摘要	利用静态箱／气相色谱法对川中丘陵区冬水田和水旱轮作稻田进行全生长季CH4排放观测。结果表明，水旱轮作稻田和冬水田CH4排放的季节变化峰值都出现在水稻生长中期，且都有1个典型的排放峰。分析讨论了温度、水稻生物量、耕作制度以及水稻栽培方式等因素对稻田CH4排放的影响。发现川中丘陵水稻生长季节5cm深处地温与稻田CH4排放通量呈显著正相关；水稻植株生长对CH4排放有重要作用；水旱轮作稻田CH4排放通量比冬水田低54．1％～65．1％；冬水田水稻采用强化栽培方式既可提高产量又可减少CH4排放。
英文摘要	Methane emission flux es from paddy fields growing rice all the year- round and paddy fields growing r ice-wheat or rapeseed in rotation were measured with the static chamber- gas chromatographic technique in hills of the central Sichuan Basin. Results show that high CH4 emission from the paddy fields under rotation and mono- rice cropping appeared in the middle of the rice growing season, and each had a typical peak. Effects of temperature, rice biomass, cropping system and planting model on CH4 emission from paddy field have been analyzed and discussed. Significant positive relationship was found between 5 cm depths of soil temperature and CH4 emission. Rice plants played an important role in CH4 emission from the paddy field. The mean CH4 emission fluxes from the paddy fields under rotation was 54. 1%- 65. 1% lower than those under mono- rice cropping during the rice growing season. The intensified rice planting model could not only raise rice yield, but also reduce CH4 emission from the paddy field.
