摘　　要：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 echo degree of seasonal variation among adjoining green space of urban street,a investigation of the greening situation in the intersection of Wushan West Road and Western Ring Road of Fuzhou was made and the similarity of seasonal changes of the green space by using the method of Vector space model also analyzed. The results indicate that： 21 species of arbor and 18 species of shrub are mainly used in the space,and in which site- A and site- C have the most abundant species and the most obvious flowering. Site- B has the least number of tree species and the flowering period is not obvious. Site- D has relatively rich deciduous species. The sort of the mean value of vector similarity among the seasonal changes of every green space is that： Site- A 〉 Site- D 〉 Site- C 〉 Site-B. The similarity ranking reflects the change of the echo degree of seasonal variation of the green space.
