Through investigating plants applied in the main streets and public greenbelts,the first-hand information about afforestation plants in Xi'an City was obtained for the first time.The results showed that,there are 136 species of plants in total belong to 102 genera,and 53 families,among which 122 species are woody plants belong to 89 genera and 44 families,i.e.89.71% of the total afforestation plants;14 species are herbaceous plants belong to 13 genera and 9 families,i.e.10.29% of the total;and there are 3 species of liana that belong to 3 genera and 2 families in woody plants with a ratio of 2.21%.The analysis showed that the landscape monotonicity was caused by the simplification of plant disposition pattern,as well as uneven quantity and frequency of applied afforestation plants.From the perspective of plant diversity,the proportion of herbaceous plants was too small;native plants were used widely which basically demonstrated the characteristics of local landscape,and most of exotic plants had obvious pantropic features which grew well in Xi'an City.This paper also analyzed problems in the present greening situation and put forward several suggestions for future tasks. 展开更多

The selection of afforestation plants,which is based on the ecotype of afforestatioin plant,is the key of plant engineering. 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
