摘要

相关性。农林系统被认为可提供多种生态服务。人们认为,农林业通过支持多样化的土地利用方式、可持续的生活方式和收入来源,以及提高森林和农业的生产力和减少与天气有关的生产损失,可增强对气候变化影响的抵御能力并帮助适应气候变化。本综述旨在提供有关农林业在生态系统保护和减轻气候变化影响方面作用的真实证据。与单一作物种植和开放式谷物农业相比,农林业对生态系统保护和减少二氧化碳排放的贡献更为显著。然而,研究发现,农林业的固碳作用低于天然林。通过地上和地下生物量固碳、减少毁林造成的碳排放以及调整小气候是减缓气候变化的关键措施。农林业系统提供了重要的生态系统服务,如食物、薪材、饲料、收入和改良土壤,使社区能够更好地应对气候变化的影响。因此,农林业要想在生态系统管理中发挥关键作用,就必须得到高度重视。

The Role of Agroforestry in Ecosystem Services and Mitigation of Climate Change
Relevance. Agroforestry systems are believed to provide a multitude of ecological services. It is thought that agroforestry enhances resilience to the impacts of climate change and aids in adaptation by supporting diverse land use practices, sustainable lifestyles, and income streams, as well as increasing productivity in both forests and agriculture, and reducing weather-related losses in production.Results and Discussion. The aim of this review was to present genuine evidence on the role of agroforestry in ecosystem conservation and mitigation of climate change impacts. Compared to monocropping and open cereal-based agriculture, agroforestry has made a more significant contribution to ecosystem conservation and in reducing carbon dioxide emissions. However, it has been found that agroforestry contributes less to carbon sequestration than natural forests. Carbon sequestration through above-ground and underground biomass, carbon emission reduction from deforestation, and microclimate adjustment are key measures for mitigating climate change. Agroforestry systems provide essential ecosystem services, such as food, fuel wood, fodder, income, and improved soil production, which enable communities to cope better with the impacts of climate change. Therefore, agroforestry must be given significant attention if it is to play a crucial role in ecosystem management.
