卫河四标段植物应用调查与评析

Investigation and Evaluation of Application in Bid Four Section of Wei River Afforested Region

在景观营造中,科学地选择园林植物并对其进行合理的配置是直接影响工程质量和景观效果的主要因素。为了解河南新乡卫河绿化后的景观效果,对卫河四标段进行了实地调查和分析。结果表明:四标段现有乔灌木及地被种类26科39属51种,其中常绿种类21种,占41.18%;落叶种类为30种,占58.82%。树种结构因子中乔灌比为0.74,常绿比为0.42,树木密度为10.97m2/株;乔木密度25.81m2/株、灌木密度19.07m2/株。群落结构以乔灌草为主,其次是乔草和灌草。

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 41.18% and 58. 82 % of total species number. However, in Bid 4 Section, one ratio of evergreen trees to deciduous ones was 0. 42, and the other one of arbor to shrub was 0. 74. Furthermore, tree density came to 10. 97 m^2 per plant, and that of arbor and of shrub was 25.81 and 19. 07 m^2 per plant, respectively. In this afforested region, most vertical communitystructure was composed of arbor, shrub and grass, but m/nor structure was/ormed by arbor and grass, or shrub and grass.
