In　order　to　systematically　study　the　spatial　and　temporal　distributions　of　biogenic　volatile　organic　compounds　(BVOCs)　emissions　in　the　Beijing-Tianjin-Hebei　(BTH)　region,　this　paper　calculated　county-level　emissions　of　BVOCs　and　major　components　in　the　BTH　region　in　2018　based　on　three　methods,　including　the　stock　production,　land　use　remote　sensing　interpretation　data,　and　MEGAN　model.　The　results　based　on　the　three　methods　showed　that　the　total　BVOCs　emissions　in　the　BTH　region　were　741400t,　844800t,　and　777300t,　respectively.　The　emissions　in　Beijing,　Tianjin,　and　Hebei　were　118000t,　32000t　and　637000t,　the　emissions　of　isoprene,　monoterpenes,　and　others　were　291900t,　225800t,　and　274100t,　and　the　emissions　of　forest　land,　cropland　and　grassland　accounted　for　68.42%,　23.07%　and　3.89%,　respectively.　From　the　perspective　of　temporal　distributions,　BVOCs　emissions　were　characterized　by　a　single　peak.　Summer　showed　the　highest　emissions　of　526400t,　accounting　for　66.64%　of　the　whole　year,　while　winter　showed　the　lowest　emissions　of　15900t,　accounting　for　2.01%　of　the　whole　year.　From　the　perspective　of　spatial　distributions,　BVOCs　emissions　based　on　different　methods　presented　similar　spatial　distribution　characteristics　of　high　emissions　in　north　and　low　emissions　in　south.　The　emissions　along　Taihang　Mountains　and　Yanshan　Mountains　were　dominated　by　forest　land　and　grassland,　while　those　in　the　southeastern　Hebei　Plain　was　dominated　by　farmland.　From　the　perspective　of　methods,　the　emissions　obtained　with　the　light-temperature　model　based　on　remote　sensing　interpretation　were　relatively　high,　and　the　proportion　of　other　BVOCs　obtained　with　the　dynamic　model　was　relatively　high.　This　study　provides　data　support　for　the　comprehensive　understanding　of　BVOCs　emission　characteristics　and　the　planning　of　continuous　air　quality　improvement　strategies　in　the　BTH　region.　©　2023　Chinese　Society　for　Environmental　Sciences.　All　rights　reserved.
