Abstract: Based on the statistics and analysis of the GIS data of forest resource inventory of management plan in Liaoning,the satellite remote sensing data of Liaoning coastal zones and the site survey data,a total of 76 families,190 genera,316 species seed plants in Liaoning coastal zones are identified,in which 40 families,74 genera are woody plants,belonging to 7 of the 15 seed plant distribution zone types in China,being 46.67%,and 58.8% of 68 families of woody plants in Liaoning.Statistics show that only a few species of woody plants of Liaoning coastal zones belong to the world distribution families,about 37.5%,but 40% of those belong to temperate zone and tropical zone families respectively.This shows that the plant flora is of the temperate zone and tropical zone property.This paper aims at giving a scientific basis for introducing woody plants,planting local species and rational allocation of tree species in the special geographical conditions of the coastal zones.

Key words: Liaoning coastal zones, woody plants, families, flora, geographical elements
