通过对不同植物群落配置的生态效应分析研究,为城市绿地植物的选择、配置、布局等提供有力的依据,并为构建最佳的城市绿地模式进行研究与探讨。在秋季和春季,选择徐州市故黄河沿岸的黄楼公园,对其植物群落的不同配置模式采用自然沉降法测定抑菌功能并分析比较。结果表明,在春季、秋季不同植物群落对空气细菌均具有一定的抑制作用;秋季植物配置模式垂柳、女贞抑菌效果最好、抑菌率均在50%左右;春季垂柳抑菌效果最佳,抑菌率为55.90%。实验表明,合理的树种选择和植物群落配置,对改善空气质量具有积极意义。
Through the analysis of the ecological effects of different plant communities, it provides a strong basis for the selection, allocation and layout of urban greenland plants, and studies and discusses the best mode of urban greenland construction. In autumn and spring, the Yellow House floor of the Yellow River in Xuzhou City was chosen. The natural sedimentation method was used to determine the bacteriostasis function of different plant models and the comparison was made. The results showed that in spring and autumn, different plant communities had certain inhibitory effects on airborne bacteria. In autumn, the weed resistance effect of weeping willows and privet flowers was the best, and the antibacterial rate was about 50% , Antibacterial rate was 55.90%. Experiments show that reasonable tree species selection and plant community configuration have positive significance for improving air quality.
