Abstract:: Both scientific filtration and appropriate ordonnance of garden plants were major factors, which directly influence engineering quality and landscape effects, during construction of landscape. For knowing landscape effects of Wei River after its afforestation, a survey and a evaluation were conducted in Bid 4 section of this region. The results showed that the plant resource was consisted of 26 families, 39 genera and 51 species, respective in the bid section, including 21 species of evergreens and 30 species of deciduous plants, which respectively accounted for 4118% and 5882% of total species number. However, in Bid 4 Section, one ratio of evergreen trees to deciduous ones was 042, and the other one of arbor to shrub was 074. Furthermore, tree density came to 1097 m2 per plant, and that of arbor and of shrub was 2581 and 1907 m2 per plant, respectively. In this afforested region, most vertical community-structure was composed of arbor, shrub and grass, but minor structure was formed by arbor and grass, or shrub and grass.
