基于DNDC模型的不同秸秆还田填埋深度下农田N2O气体排放模拟
Simulation of Nitrous Oxide Emission under Different Straw Retention Depths Based on Denitrification-Decomposition Model
摘要
Abstract
This research combined the paddy planting season data in Wujiang region,China with the DNDC model(Denitrification-Decomposi-tion model) to detect whether the DNDC could be used to simulated the N2O emission speed,annual discharge amount and discharge change tend-ency.This research also analyzed the sensitivity of the important factors which affect the N2O discharge amount.The results were as fellows:DNDC model could be used to simulate the N2O emission speed,annual discharge amount and discharge change tendency under different straw retention soil depths.The annual mean temperature,soil pH,soil organic carbon amount,fertilization amount and straw retention amount could influence the N2O gas discharge amount sensitively.关键词
