摘要：
By using the program CALMIM (California landfill methane inventory model), the methane emission in three typical landfills of China (Shanghai Laogang landfill, Hangzhou Tianziling landfill and Xi'an Jiangcungou landfill) were numerically simulated, and the influences of climate, vegetation coverage and methane oxidation rates on emission of methane in landfills were analyzed. The results show that methane emission amount in Jiangcungou landfill is obviously higher than that of Laogang landfill and Tianziling landfill, and methane emission amount of Laogang landfill in Shanghai is higher than that of Tianziling landfill in Hangzhou. Two seasonal factors are considered, including temperature and precipitation, without considering methane oxidation, the largest and smallest quantities of methane emission amount of Jiangcungou landfill are in August and November, which are 94 kg/m3 and 65 kg/m3 respectively. But the largest and smallest quantities of methane emission of Tianziling landfill are in January and September, which are 14 kg/m3 and 6 kg/m3 respectively. The vegetation coverage can reduce the methane emission amount, but this tendency is not obvious. When the maximum methane oxidation rate equals to 50 μgCH4 gsoil-1 d-1, methane emission amount without considering oxidation is 6.36 times that of considering oxidation, and emission amount of methane is close to zero when the oxidation rate of methane is greater than 100 μgCH4 gsoil-1 d-1. © 2016, Editorial Department of Journal of Southeast University.
