摘要

减轻气候变化和全球城市化的不利影响是地方当局和城市管理者的主要任务之一。作为一项长期解决方案,城市和城郊森林有可能通过提供生态系统服务来减轻气候变化的影响,如去除空气污染物、缓解城市热岛、储存碳、调节当地气候、限制洪水风险、降低噪音水平、改善公民的身心健康及其福利。为了促进、保护和提高城市周边森林的效益,需要充分描述森林生态系统的状态,并了解其结构和功能。本研究的目的是调查布加勒斯特城郊主要森林之一的结构、多样性和健康状况。2015年和2020年,在永久样本监测网络(PSMN)中进行了生物物理测量(胸径、总高度、木材质量、生态等级)和森林健康状况评估。该PSMN由位于罗马尼亚布加勒斯特附近的城市周边Stefănești森林中的46个样地组成。利用Shannon (H)指数和Gini (G)指数对树种多样性进行表征。我们的研究证实,林分水平上较高的树种多样性指数和生物特征变异维持了生态系统对气候变化的恢复和适应能力,同时增强了它们提供各种生态系统服务的能力。获得的见解对于帮助森林管理者、政策制定者和任何利益相关者评估和建立生态系统服务模型至关重要。

Structure and diversity in a periurban forest of Bucharest, Romania
Mitigating the adverse effects of climate change and worldwide urbanization is one of the main tasks of local authorities and city managers. As a long-term solution, urban and periurban forests have the potential to mitigate the impacts of climate change by providing ecosystem services such as removing air pollutants, mitigating the urban heat islands, storing carbon, regulating local climate, limiting the risk of flooding, reducing noise levels, and improving the physical and mental health of citizens and their welfare. To promote, conserve, and enhance the benefits offered by the periurban forests, it is needed to adequately describe the forest ecosystems state, and understand well their structure and functionality. The objective of this study was to investigate the structure, diversity, and health status of one of the main periurban forest in Bucharest. In 2015 and 2020, biophysical measurements (diameter at breast height, total height, wood quality, cenotic class) and assessments of forest health status were conducted in a permanent sample monitoring network (PSMN). This PSMN consists of 46 sample plots located in the periurban Stefănești forest near Bucharest, Romania. The calculation included tree characteristics and stand volumes, while the tree species diversity was characterized using the Shannon (H) and Gini (G) indexes. Our study confirmed that higher diversity indexes of tree species and variability amongst the biometric characteristics at forest stand level sustain ecosystem resilience and adaptability to climate change, simultaneously bolstering their capacity to provide various ecosystem services. The gained insights are critical in helping forest managers, policymakers, and any stakeholders in the effort to evaluate and model the ecosystem services.
