| 摘 要： | 目的 研究浙江省不同地区毛竹Phyllostachys edulis林空间结构特征及其差异性。 方法 以浙江省不同地区近自然生长的毛竹林为研究对象,共设置54个样地,采用聚集指数、竞争指数和年龄隔离度3个空间结构指数。 结果 浙江省不同地区毛竹林竞争指数为2.88~8.81,其中余姚地区最大,庆元地区最小;年龄隔离度为0.30~0.84,其中黄岩地区最大,武义地区最小;聚集指数为0.73~1.24,其中宁海地区最大,余姚地区最小。浙江省不同地区毛竹林年龄隔离度和聚集指数没有显著差异,而不同地区间竞争指数存在显著差异（P < 0.05）。 结论 浙江省毛竹林空间分布格局以聚集分布为主。空间结构指数存在一定的区域变化趋势,从北到南竞争指数逐渐减小。

| Abstract: | Objective Spatial structure characteristics and differences of moso bamboo (Phyllostachys edulis) forests in different regions of Zhejiang Province were studied. Method The close-to-nature moso bamboo forests in different regions of Zhejiang Province were taken as the research objects, 54 sample plots were set up, and spatial structure indices (aggregation index, competition index and age mingling) were used to analyze spatial structure characteristics and differences of moso bamboo forests in different regions of Zhejiang Province. Result The mean competition index of moso bamboo forest in different regions of Zhejiang Province is 2.88-8.81, among which Yuyao is the largest and Qingyuan is the smallest. The mean age mingling is 0.30-0.84, the largest in Huangyan and the smallest in Wuyi. The mean aggregation index is 0.73-1.24, the largest in Ninghai area and the smallest in Yuyao area. There was no significant difference in age mingling and aggregation index among different regions in Zhejiang Province, whereas there was significant difference in competition index among different regions in Zhejiang Province(P < 0.05). Conclusion The spatial distribution pattern of moso bamboo forests in Zhejiang Province was mainly aggregated distribution. The spatial structure index has a certain regional variation trend, and the competition index decreases gradually from north to south. |
