Effects of soil moisture and temperature on N2O production rate of meadow grassland soil

Abstract

Abstract: With incubation test, this paper studied the effects of soil moisture and temperature on the N₂O production rate of meadow grassland chernozem in nner Mongolia. The results showed that soil moisture had a significant effect on the N₂O production rate, with a non-linear relationship between them. Soil temperature had less effect than soil moisture. Their effects on the test soil N₂O production rate at different growth stages could be described as a multi-rder polynomial relationship y=ax³+bx²+cx+d, where a, b, c and d were the constants.

Key words: Forest Landscape, Changbai Mountain, GIS, Remote sensing
