为探究城市街头相邻绿地间植物季相变化呼应程度,对福州市乌山西路与西环路交叉口的绿化情况进行调查,并应用向量空间模型对其绿地季相变化相似度进行分析。结果表明,主要运用了21种乔木树种和18种灌木树种,其中A位置和C位置绿地树种最丰富,且花期最为明显;B位置绿地的树种最少,且花期相对不明显;D位置绿地的落叶树种相对丰富。各绿地的季相变化向量相似度均值排序为:A位置>D位置>C位置>B位置,相似度的排序反映了各绿地间季相变化的呼应程度大小。
In order to explore the degree of plant seasonal change in the adjacent greenbelt of urban street, the greening situation of the intersection of Wushan West Road and Xihuan Road in Fuzhou was investigated and the similarity of seasonal change of greenbelt was analyzed by vector space model. The results showed that 21 kinds of tree species and 18 kinds of shrub species were mainly used. Among them, the species of A and C were the most abundant and had the most obvious flowering stage; the species of B in the green space was the least and the flowering period was relatively insignificant; Relatively rich species. The order of similarity of seasonal variation vector of each green space is: A position> D position> C position> B position, and the order of similarity reflects the degree of echo of seasonal change of each green space.
