摘要

公园、广场和绿树成荫的街道等城市绿地是以自然为基础的解决方案 (NBS) 的一部分,可为解决这些城市问题提供生态系统服务。然而,人们对树种的贡献以及公共管理下城市树木提供的整体生态系统服务了解有限,尤其是在拉丁美洲。本研究旨在提供利马市(秘鲁)城市树木在减少二氧化碳、颗粒物(PM2.5 和 PM10)和温室效应气体化合物(GEG)等高发污染物方面所作贡献的信息,使用的软件工具是用于估算生态系统服务的 I-tree 软件包。结果表明,利马公共管理下的城市树木在减少污染物、封存二氧化碳方面做出了重大贡献,其封存量接近拉丁美洲温带原生林水平的 50%,高于同一地区一些旱生原生林的测量值。其他被评估的污染物水平也显著降低。树种之间的差异也被观察到,这表明柽柳(Ficus pertusa L. f.)和红桉(Eucalyptus camaldulensis Dehnh.)对减少污染物的贡献更大,而Erythrina falcata Benth.作为一种本地树种,具有显著的碳储存能力(1.27吨/个)。这些信息对参与城市规划和管理(尤其是城市树木管理)的专业人员和公共机构具有重要意义。它表明,树种选择会影响城市污染物水平的缓解,同时增加其他生态系统服务,从而有助于改善市民的健康。

Contribution of urban trees to carbon sequestration and reduction of air pollutants in Lima, Peru

Urban green areas, such as parks, squares, and tree-lined streets, are part of nature-based solutions (NBS) that provide ecosystem services to address these urban issues. However, there is limited knowledge about the contribution of tree species and overall ecosystem services provided by urban trees under public management, especially in Latin America. This study aimed to provide information on the contribution of urban trees in reducing highly incident pollutants, such as CO2, particulate matter (PM 2. 5 and 10), and greenhouse effect gas compounds (GEG) in the city of Lima (Peru), using the I-tree package software tool for estimating ecosystem services. The results demonstrate that urban trees under public management in Lima significantly contribute to pollutant reduction and the sequestration and storage of CO2 in the city, being that storage is nearly 50% of the levels observed in native temperate forests in Latin America and higher than the value measured in some xerophytic native forests in the same region. Other evaluated pollutantś levels are significantly reduced. Differences among tree species were observed, showing amatillo (Ficus pertusa L. f.) and red eucalyptus (Eucalyptus camaldulensis Dehnh.) as higher contributions to pollutant reduction, with Erythrina falcata Benth. as a native species having significant carbon storage (1,27 t/individual).

This information is highly relevant for professionals and public institutions involved in urban planning and management, particularly urban tree management. It shows that tree species selection influences the mitigation of pollutant levels in cities while increasing other ecosystem services, thereby contributing to improving citizens' health.

期刊介绍: Ecosystem Services is an international, interdisciplinary journal that is associated with the Ecosystem Services Partnership (ESP). The journal is dedicated to exploring the science, policy, and practice related to ecosystem services, which are the various ways in which ecosystems contribute to human well-being, both directly and indirectly. Ecosystem Services contributes to the broader goal of ensuring that the benefits of ecosystems are recognized, valued, and sustainably managed for the well-being of current and future generations. The journal serves as a platform for scholars, practitioners, policymakers, and other stakeholders to share their findings and insights, fostering collaboration and innovation in the field of ecosystem services.
