The green infrastructure of the city of Novi Sad is characterized by a significant presence of ornamental invasive alien species, which might lead to their uncontrolled spread and suppression of autochthonous dendroflora. This study aimed to determine the ecosystem services and disservices of ornamental dendroflora in Novi Sad, as well as how they can affect urban green areas. Of the total ornamental dendroflora in Novi Sad, 88.33% of species with a good adaptation were determined, while 10% had a medium and 1.67% had a very good adaptation. Thirty-four allochthonous species showed very high (38.24%), moderate (47.06%), and low (14.71%) invasive potential according to the conducted invasiveness risk assessment. These species are also characterized by high (2.94%), moderate (67.65%), and low (29.41%) allergenic potential. On the contrary, 26 ornamental autochthonous species are characterized by moderate (38.46%) and low (61.54%) rates of spread on public green areas, while also characterized by high (26.92%), moderate (50%), and weak (23.08%) allergenic potential. Ornamental dendroflora provides many more positive ecosystem services, such as urban afforestation, climate regulation, decorative-aesthetic value, air and water purification, ecotourism and recreation, and other services that are of great benefit to the residents of that city. The highest calculated values of ecosystem services in allochthonous and autochthonous species were 27 and 26.5 (out of possible maximal value 40), while ecosystem disservices accounted down to the value of - 13.5 (out of possible minimal value - 22). Therefore, intrinsic disservices such as the production of large amounts of green waste of ornamental dendroflora can be shifted into a novel ecosystem service-green solutions based on nature, to avoid unsuitable deposition of seeds in the soil and creation of suitable vegetation on public green areas.
诺维萨德市的绿色基础设施以大量观赏性外来入侵物种为特征，这可能导致它们不受控制地扩散并抑制本地树木植物群。本研究旨在确定诺维萨德市观赏性树木植物群的生态系统服务和负效应，以及它们如何影响城市绿地。在诺维萨德市的观赏性树木植物群中，确定了88.33%适应良好的物种，而10%适应中等，1.67%适应非常好。根据进行的入侵风险评估，34种外来物种显示出非常高（38.24%）、中等（47.06%）和低（14.71%）的入侵潜力。这些物种还具有高（2.94%）、中等（67.65%）和低（29.41%）的致敏潜力。相反，26种观赏性本地物种在公共绿地上的传播速率为中等（38.46%）和低（61.54%），同时也具有高（26.92%）、中等（50%）和弱（23.08%）的致敏潜力。观赏性树木植物群提供了更多积极的生态系统服务，如城市造林、气候调节、装饰美学价值、空气和水净化、生态旅游和娱乐，以及其他对该市居民非常有益的服务。外来物种和本地物种生态系统服务的最高计算值分别为27和26.5（可能的最大值为40），而生态系统负效应低至-13.5（可能的最小值为-22）。因此，诸如观赏性树木植物群产生大量绿色废物等内在负效应可以转化为一种新的基于自然的生态系统服务——绿色解决方案，以避免种子在土壤中不适当的沉积，并在公共绿地上创造适宜的植被。
