| 摘 要： | 通过建立野外采样系统,对一个生长周期内水稻土释放的挥发性含硫气体进行了检测.研究结果表明:水稻土中释放的含硫气体主要为COS、CS2和DMS,并有少量的DMDS.估算出的各含硫气体的释放通量分别为81.11、6.33和10.71 mg·(m2·a)-1.我国水稻土释放含硫气体的通量为(S)0.013662 Tg/a,全球为(S)0.07992Tg/a |

| Abstract: | In the paper, emission of volatile sulfur gases from paddy soil was discussed in a growth period of paddy rice by constructing a field sampling system. The result showed that COS, CS2, DMS and DMDS were mainly emitted from paddy soil. The order of emission fluxes was 81.11, 6.33 and 10.71 mg.(m2.a)-1. Sulphur emission fluxes of Chinese paddy soil was 0.013662 Tg/a, and those of world paddy soil was 0.07992 Tg/a. |
| Keywords: | paddy soil volatile sulfur gases emission |
