Abstract:		"Biogenic volatile organic compound (BVOC) is an important part of forest healthcare effect, while it has not received enough attention in urban greenspace construction. Consequently, the aim of this study was to analyze BVOC emission rates and compositions released from leaves and flowers of landscape species in urban greenspace and to make suggestions for species selection and planting configuration in urban greenspace construction. BVOC emissions were collected and analyzed using dynamic flow enclosure technique with GC-MS in summer months (for leaf) and spring months (for flower) from 14 woody landscape species in northern China, which are 2 coniferous species (Pinus tabuliformis and Sabina vulgaris) and 12 broad-leaved species (Viburnum opulus, Kolkwitzia amabilis, Philadelphus pekinensis, Lonicera maackii, Cercis chinensis, Deutzia parviflora, Berberis thunbergia, Kerria japonica, Rosa xanthina, Syringa oblata, Syringa reticulata, and Cerasus serrulata). We found leaf emission rates of coniferous species were more than 20 mug?O+g(-1)Dw?O+h(-1) and mainly consisted of monoterpenes, while that of sampled broad-leaved species were less than 10 mug?O+g(-1)Dw?O+h(-1) and mainly consisted of fatty acid derivatives. Most broad-leaved species had relatively high emission rates of flowers, ranging from 15 to 115 mug?O+g(-1)Dw?O+h(-1). Flower emissions of Syringa oblata and Syringa reticulata contained large amounts of aldehydes, and that of other broad-leaved species mainly contained terpenes, alcohols, and esters. We suggest the species with leaves that release large amounts of monoterpenes, and species with flowers that release large amounts of fragrant compounds are classified as healthcare species, while species with a dense crown and low emission rates of pungent compounds are classified as space-creation species. Based on this, planners could design urban greenspace with healthcare effects, and develop multi-functional, innovative, and sustainable urban greenspaces"
