摘要: 通过对陕西关中地区绿地绿篱树种资源及造景现状调查,结果表明在该地区应用的绿篱树种涉及25科,77种。其中常绿、半常绿树种33种占42.9%;落叶树种有44种,占57.1%。观叶树37种,观花树40种,观果16种,具刺树种8种。通过对调查的绿篱资源的应用与造景现状分析,存在绿篱植物多样性差、营造的景观雷同、多地管理粗放和造景效果不佳的问题。该文提出生态优先,加强乡土树种的应用,适度引用外来种,大力开发当地野生资源来丰富植物多样性;运用绿篱造景要坚持多样与统一、协调与对比、均衡、韵律和节奏变化、融入文化内涵的原则,以增强景观异质性;通过加强从业人员的培训,提高管理技术水平,以提升绿篱景观观赏价值。Abstract: Based on investigation of resources and landscape of hedgerows in Guanzhong area of Shaanxi province,results showed that there were 25 families and 77 species of hedgerows in the area.Among them,33 species of evergreen and semi-evergreen species accounted for 42.9%,44 species of deciduous species accounted for 57.1%,and there were 37 species of foliage trees,40 species of ornamental flowers,16 species of ornamental fruits and 8 species of thorns.Through investigation of application of hedgerow resources and landscape analysis of current situation,there was a problem that hedgerows were not highly diverse and create similar landscapes.They also had extensive management of landscaping and poor landscaping.Ecological priority was given to strengthen application of native tree species,appropriate use of exotic species,and vigorously develop the local wild resources to enrich plant diversity.The use of hedging landscapes should adhere to principle of diversity and unity,coordination and contrast,balance,rhythm and tempo,and cultural connotation so as to enhance landscape heterogeneity.By strengthening training of practitioners and raising level of management skills to enhance ornamental value of hedgerow landscape.
