摘　　要：文章首次对山东省果树资源的18个科,34个属,92种34个变种的组成成分和区系成分进行了统计分析.该地区包括9个分布区类型:北温带分布5科17属,世界分布4科2属,东亚及美洲间断分布3科1属,泛热带分布2科4属,地中海区中亚至西亚分布2科3属,旧世界热带分布1科1属,东亚分布1科2属,旧大陆温带及变型3属,热带亚洲美洲间断1属,可见北温带分布成份占有重要地位,北温带成份科占总科数的27.78%,北温带成份属共有17属占总属的50.00%.There are 92 species of woody plants attached to 34 genera and 18 families in Shandong province.We analyse the components and floristic elements of fruit plants for the first time in this paper.Shandong＇s fruit plants can be divided into 9 distribution types,among which,North Temperate 5 families,17 genera,world distribution 4 families,2 genera,and East Asia and the Americas discontinuous distribution of 3 families 1 genera,pan-tropical distribution of 2 families,4 genera,distribution of the Mediterranean area from Central Asia to West Asia,3 genera in 2 families,Old World tropical distribution 1 genus in1 family,1 family 2 genera is distributed in East Asia,the old continent is temperate and variant 3 genera,1 genera of tropical Asia,Americas,intermittent,can be seen north temperate elements play an important role.North temperate components division the number of total families 27.78%,north temperate component of total genera of the 50.00%
