| 摘 要： | 对成都市不同类别的5个公园绿地进行抽样调查,对其物种组成、优势度与多样性指数等进行了统计和分析。调查表明:成都市公园绿地保存有较丰富的古老、珍稀树种资源;各公园乔木层优势度指数偏低,神仙树公园(社区公园)最高;以新益州公园物种多样性最为丰富。总体而言,乔木的多样性指数大于灌木。根据对物种多样性及乔木层优势度的分析,对各公园的群落组成、结构特点提出了改造建议。

| Abstract: | Through conducting a sample survey of five different types of park greenbelts in Chengdu, their species composition, the dominance, and the diversity index were calculated and analyzed. The result showed that the ancient rare tree resource was abundant in park greenbehs in Chengdu. The tree dominant index of Shengxianshu Park was higher than other parks. The diversity index of Xinyizhou Parks was higher than other parks. To sum up, the tree diversity index was higher than the shrub. Based on those above, the reasonable suggestion of the species composition, structure characteristics and the improvement were proposed. |
