广州城市公园不同绿地植物群落配置模式的抑菌功能分析

以广州市3个公园不同配置模式的植物群落为样地,测定分析其抑菌功能。结果表明:植物群落具有良好的抑菌作用;抑菌效果强度大小依次是乔灌草结构乔草结构草坪结构灌草结构;植物群落的抑菌效果在不同时刻的表现也不尽相同,乔灌草、灌草和草坪的抑菌效果均在16:00达到最好,灌草和草坪结构在8:00最差。

Antibacterial Function of Plant Community under Different Collocation Patterns of Urban Parks in Guangzhou

An experiment was conducted to study the antibacterial function of plant communities under different collocation patterns in three urban parks in Guangzhou city as the testing objects. The results showed that the plant communities had good antibacterial action, which was decreased in order of T+S+H>T+H>L>S+H. The antibacterial actions at different times of the day varied with the different plant structures. The first three plant community structures got the best antibacterial effects at 16:00, i.e., T+S+H, S+H, and L, and the latter two got the worst at 08:00.
