【摘要】 通过对长沙城市固体废弃物处理场的周边区域地面气象观测和高空气象探测一年的资料进行分析,并结合国家气象观测站网构建了垃圾填埋场的小尺度气候模型,结合观测场气候空间特征,文章研究了固体废弃物处理场周边的小尺度气候条件,并应用AERMOD大气扩散模型,研究并验证了固体废弃场在山地气候条件下的恶臭扩散过程,得出了该污染源恶臭浓度受气候影响较明显,且在气温、风速风向等气象条件,恶臭扩散表现出不同的气候条件下的时空分布特征。更多还原

【Abstract】 This work address the problem of discovering the way of pollution of landfill located in Changsha,Hunan Province.By analysis the climate record from automatic weather station nearby the landfill at different times,a series simulation about landfill pollution is made with the air-pollution mode( AERMOD). From this simulation,the study got more information about the pollution-dispersion of the landfill. The result of simulation tell a true that the rule of the landfill is consist with the climate and the landform of there and In southwest of landfill,the pollution of landfill is worse than the others part of there.更多还原
