There is not final verdict yet on the standard of ecotype of afforestation plant. According to the presentational feature （regional distribution,Climatic indicator）,ecotype （climatoecological type,edaphic ecotype and biota ecotype） and genetic association of afforestation plant,combined with the experience in the greening practice,the afforesting nursery stock （Arbor and Shrub ） is divided into five ecotypes while the herbaceous plant are divided into three ecotypes.展开更多
