Based on the data of land use, meteorological data, leaf area index and Palmer drought index of 2015, the GLOBEIS model was utilized to calculate the emissions of biogenic, and the emissions inventory of biogenic VOCs in Urumqi was established. The results showed that the total emissions of biogenic VOCs in 2015 was approximately 13750.72t, of which isoprene, monoterpene and other VOCs were 77.00t, 5057.51t and 8616.20t, accounting for 0.56%, 36.78% and 62.66%, respectively. The emissions intensity of the total emissions of the biogenic VOCs was 1.82t/(km2.a). The temporal distribution of VOCs emissions ranked summer > spring > autumn > winter; the spatial distribution of biogenic VOCs were mainly focused on the middle of Urumqi County, Dabancheng district and the south of Midong district.
