摘　　要：为明确填埋场甲烷释放的时空变化规律及其影响机制,以青岛某生活垃圾填埋场为例,采用静态箱法测定了不同季节甲烷释放通量日动态变化.结果表明,填埋场甲烷释放通量季节变化显著,冬季释放最高为(115.67±65.34)mmol/(m^(2)·h),夏季释放最低为(61.51±74.57)mmol/(m^(2)·h).不同季节的日甲烷释放通量存在明显差异,夏季甲烷释放通量呈现双峰曲线,秋冬季甲烷释放通量呈现单峰曲线.相关性分析表明甲烷释放通量与大气压、大气温度、大气相对湿度、风速、土壤温度、土壤相对湿度显著相关;夏秋季甲烷释放通量与大气相对湿度和大气温度分别呈显著正相关和负相关,而冬季则相反.To clarify the temporal and spatial variation patterns of methane emissions from landfills and their influencing mechanisms,a case study was conducted at a municipal solid waste landfill in Qingdao.The static chamber method was used to measure the diurnal dynamics of methane emission fluxes across different seasons.The results indicate significant seasonal variations in methane emission fluxes from the landfill,with the highest emissions occurring in winter at(115.67±65.34)mmol/(m^(2)·h)and the lowest in summer at(61.51±74.57)mmol/(m^(2)·h).The diurnal methane emission fluxes also varied markedly between seasons,with summer fluxes exhibiting a bimodal curve and autumn and winter fluxes showing a unimodal curve.Correlation analysis revealed that methane emission fluxes were significantly related to atmospheric pressure,air temperature,relative humidity,wind speed,soil temperature,and soil relative humidity.In summer and autumn,methane emission fluxes showed a significant positive correlation with atmospheric relative humidity and a negative correlation with air temperature,whereas the opposite was true in winter.
