| 通过对广州市8个公园内蜜源植物实地调查，探讨了广州市城市公园绿地秋季开花植物与蜂蝶类传粉者之间的关系。结果表明：8个公园内秋季蜜源植物107种，隶属47科90属，65种植物处于花期；传粉者以蜂蝶类为主，在9:00—11:00时和13:00—15:00时是访花高峰时期，蜂类在各时段的访花频次高于蝶类；海珠湖公园、海珠国家湿地公园以及白云湖公园（东湖）的蜜源植物种类和传粉昆虫访花频次均高于其他公园；植物的花部特征和物候期对吸引传粉昆虫传粉存在一定影响。因此，根据园林植物的开花特性和传粉者吸引能力，合理应用园艺品种和外来植物，科学配置蜜源植物景观，有利于城市园林植物传粉，对城市森林生态系统具有重要意义。 |

| Abstract: |
| Based on the field investigation of nectariferous plants in eight parks in Guangzhou, the relationship between the autumn flowering plants and bee butterfly pollinators in urban parks in Guangzhou was discussed. The results showed that there were 107 species of nectar plants belonging to 90 genera and 47 families in the eight parks in autumn, and 65 species were in the flowering stage. The pollinators were mainly bees and butterflies. There were two peak periods of visiting flowers from 9:00-11:00 a.m and 13:00-15:00 p.m, and the frequency of visiting flowers of bees was higher than that of butterflies. In Haizhu Lake Park, Haizhu National Wetland Park, and Baiyun Lake Park (East Lake), the species of nectar source plants and the frequency of pollinating insects visiting flowers were all higher than other parks. The flower characteristics and phenological period of plants have a certain influence on attracting pollinating insects. Therefore, according to the flowering characteristics of garden plants and the attraction ability of pollinators, the rational application of garden varieties and exotic plants, and the scientific allocation of nectar plant landscapes are beneficial to the pollination of urban garden plants, which is of great significance to the urban forest ecosystem. |
