摘　　要：以杭州为研究区域,香樟为研究对象,定点观测香樟物候,利用年轮指数分析香樟生物量累积的年度变化,研究杭州市香樟生长状况。以农村区域为对照,计算时间序列上城市化对树木年轮的生态效应指数(Eu)。结果表明:Eu在1994年前为-0.10、1998年后为0.13,表明杭州城市化在时间尺度上对香樟生物量累积的生态效应由抑制转变为促进作用;城市区域香樟物候期提前20d,总生长季增加约2个月。The growth of Cinnamomum camphora L. Presl in Hangzhou was researched base on the long-term fix spot observation of phenophase at urban and rural areas. The plant biomass growths along time series were investi-gated using the tree ring width analytical method;the ecology impacts of urbanization on annual ring width index of Cinnamomum camphora L. Presl was quantitive analyzed. The results indicated that the ecology effect index （Eu） was-0.10 before 1994 but change to a positive value of 0. 13 after 1998,indicated that the ecology impact of urbanization on Cinnamomum camphora L. Presl was changed from negative to positive effect. Plant phenophases in urban sites were about 20 days ahead of the time at rural areas,and the total growth period extended for about 2 months.
