Study on the relation between paddy field temperature and methane emission flux
稻田温度与甲烷排放通量关系的研究

There are consanguineous connections between the paddy field temperature and the methane emission flux. After analyzing four kinds of temperature by gray association, the results show that the paddy field temperat ure at 5 cm below is the closest one. The methane emission flux attains the max. in the tassel period and attains the min. in the ripe period. The temperature increasing effect is clearer than the decreasing effect. Finally, the correlati vity between paddy field temperature and the methane emiss ion flux submits to the curve of S.
