乡土植物在广元城市园林绿化中的应用

Application of indigenous plants in urban landscaping of Guangyuan

对广元城市园林绿化进程中乡土植物的应用情况进行了分析研究,按其使用程度将乡土植物分为3类:1应用广泛;2应用较少;3尚未驯化,具有潜在开发价值。在城市绿化建设中,广元利用乡土植物构建了观赏型、环保型、保健型、科普知识型、生产型和文化环境型6种城市绿地植物群落功能类型,并以点、线、面相结合的典型方式,将乡土植物及不同的群落功能类型应用于城区公共绿地建设,构建了富有地域文化特色的植物景观。

The application situation of indigenous plants was analyzed in urban landscaping of Guangyuan. Based on the degree of utilization, native plants could be divided into three classes ： widely, seldom, not yet and potentially valuably. In the urban afforestation construction, Guangyuan applied indigenous plants and constructed 6 types of plant functional communities, including ornamental type, environmental protection type, health care type, popular science type, produc- tive type and cultural type. By way of the point-line-surface model, these indigenous plants and plant functional communi- ties were widely used in public greenland and those plant landscapes with historical and cultural characteristics.
