摘要
植物物候是反映生态系统响应环境变化的重要指标。文中聚焦于城市化对景观植物花期物候的影响,总结国内外物候监测方法的发展历程,归纳出景观植物花期物候变化的主要规律,提炼出影响城市植物花期物候变化的环境驱动因子及其常用物候模型,明确现有研究中存在的短板及未来研究方向。研究分析得出,在北美、欧洲和亚洲等多个城市的生态系统中,景观植物的花期物候总体呈现提前趋势,且比乡村栖息地更早地进入花期;春花和虫媒授粉植物更易受到城市化的影响。但城市化对花期物候变化的作用机制仍然未知,其潜在生态后果亦难以明确。在未来需发展新的物候观测技术,从不同空间尺度开展实证研究以阐明以上问题。
Plant phenology is an important indicator of ecosystem response to environmental changes.With the view to understanding the impact of urbanization on flowering phenology of landscape plants,the paper summarizes the development process of national and international phenology monitoring methods,concludes the changing rule of flowering phenology of landscape plants,extracts the environmental factors affecting the changes of flowering phenology as well as the universal phenology models,and identifies the gaps in existing studies and the future research directions.Results show that the landscape plants in many urban ecosystems in North America,Europe and Asia have generally an advance in flowering phenology,and enter the flowering period earlier than those in rural habitats,and that spring flowers and insect pollinators are more susceptible to the impacts of urbanization.However,the working mechanisms of urbanization on flowering phenology are still unknown,and the potential ecological consequences are also difficult to assess.In the future,the new observation technology should be developed and the empirical studies should be implemented at different spatial scales to clarify the above issues.
