Compared with general upland fields, the effect could be expected that nitrous oxide emission would be reduced as the twice or more. Soil moisture condition was shown toward decreasing of greenhouse emissions and strengthening of water quality purification capacity. The farmland was defined, "New Multi-Purpose Paddy Field". In the New Multi-Purpose Paddy Field, it was proven not only to the environmental conservation of reactive nitrogen, but also to be able to preserve soil and water resources with steady crop yield for each unit area. Additionally, the amount of denitrification was derived by using quadratic function type of which the variable was underground water temperature.

与一般旱地相比，一氧化二氮排放量可减少一倍或两倍以上。土壤水分状况表现为温室气体排放减少，水质净化能力增强。农田被定义为“新型多用途水田”。在新的多功能稻田中，不仅证明了活性氮的环境保护，而且能够保持水土资源，单位面积作物产量稳定。采用以地下水温度为变量的二次函数式，求出了反硝化量。
