摘要
上海广富林郊野公园作为城市绿地的一个典型案例,其自生草本植物群落的季节性变化和多样性对于城市生态系统的功能和服务较为重要。该研究通过对广富林郊野公园春季与秋季草本植物群落的比较调查,分析了植物群落的季节性变化特征、物种多样性指数的季节性差异,以及不同管理强度对其群落结构和生态服务功能的影响。结果表明,生物多样性和功能多样性在弱干扰地块显著高于强养护地块,因此,减少人为干扰有助于生物多样性的恢复。该研究为城市绿地生态恢复和可持续管理提供依据,对促进城市生态系统的健康和可持续发展具有一定的意义。
As a quintessential urban green space,Shanghai Guangfulin Country Park plays a certain role in the functionality and services of urban ecosystems through the seasonal variation and diversity of its native herbaceous plant communities.This study conducted comparative surveys of the herbaceous plant communities in the park during spring and autumn to analyze the seasonal characteristics of the plant communities,the seasonal differences in species diversity indices,and the impact of varying management intensities on their community structure and ecosystem service functions.The findings indicated that biodiversity and functional diversity were significantly higher in areas with weak human disturbance compared with those under intense management,suggesting that reducing human interference contributed to biodiversity restoration.This research offers a basis for ecological restoration and sustainable management of urban green spaces,and has certain significance for promoting the health and sustainability of urban ecosystems.
