A　newly　developed　static　chamber　method　with　a　laser　methane　detector　and　a　biogas　analyser　was　proposed　to　measure　the　landfill　gas　emissions　and　methane　(CH4)　oxidation　rates　in　landfill　covers.　The　method　relied　on　a　laser　methane　detector　for　measuring　CH4　concentration,　avoiding　gas　samplings　during　test　and　hence　the　potential　interference　of　gas　compositions　inside　the　chamber.　All　the　measurements　could　be　obtained　on　site.　The　method　was　applied　to　determine　the　landfill　gas　emissions　and　CH4　oxidation　rates　in　a　full-scale　loess　gravel　capillary　barrier　cover　constructed　in　landfill.　Both　laboratory　calibration　and　in-situ　tests　demonstrated　that　fast　(i.e.　<20　min)　and　accurate　measurements　could　be　obtained　by　the　proposed　method.　The　method　is　capable　of　capturing　the　significant　spatial　and　temporal　variations　of　the　landfill　gas　emissions　and　CH4　oxidation　rates　in　landfill　site.　©　The　Author(s)　2019.
