山地城市园林植物物候相调查分析

Analysis and Investigation of Phenology of Landscape Plants Applied in the Mountain Cities

为了研究山地城市园林植物物候规律,对重庆市主城区12个公园8个居住区11个道路2个自然林的植物种类进行调查。统计出主城区常见的园林绿化植物有519种,隶属于111科330属;其中乔木类67科236种,灌木类58科(禾木类与灌木类科类有重合) 161种,藤本类11科17种,草本类32科105种。结合文献统计了植物的花期、果期等物候相,总结了山地城市园林植物的季节性景观特征。

In order to study the phenological laws of mountain urban landscape plants, the plant species in 12 parks, 8 residential areas, 11 roads and 2 natural forests in the main urban area of Chongqing were investigated and studied. According to the statistics, there were 519 species of common landscaping plants in the main urban area, belonging to 330 genera of 111 families. Among them, there were 236 species in 67 families of trees, 161 species in 58 families of shrubs（trees and shrubs overlapped）, 17 species in 11 families of vines and 105 species in 32 families of herbs. At the same time, the florescence and fruiting phases of plants were calculated according to the literatures, and the seasonal landscape characteristics of garden plants in mountain cities were summarized.
