This plays a fundamental role in balancing the world’s carbon cycle and helping to combat climate change世界森林每年清除的二氧化碳估计为21亿吨。这在平衡世界碳循环和帮助应对气候变化方面发挥着根本作用 ;18;19;Forest Ecosystem (service)森林生态系统的服务;Grassland ecosystems草原生态系统;Grassland ecosystems草原生态系统;Grassland ecosystems草原生态系统;Grassland ecosystems草原生态系统;Grassland ecosystems草原生态系统;Ecosystem function and services;Ecosystem function and services生态系统功能和服务;Higher biodiversity usually increases ecosystem efficiency and productivity, stabilizes overall ecosystem functioning, and makes ecosystems more resistant to perturbations更高的生物多样性通常会提高生态系统的效率和生产力, 稳定整个生态系统的功能, 并使生态系统更能抵御扰动 Mobile, connected animal species provide critical ecosystem functions and increase ecosystem resilience by connecting habitats and ecosystems through their movements移动、互联的动物物种通过移动连接生境和生态系统, 提供关键的生态系统功能并提高生态系统的复原力 Their services include pollination, seed dispersal, nutrient deposition, pest control, and scavenging他们的服务包括授粉、种子传播、养分沉积、虫害控制和清理 Thousands of plant species that are the components of ecosystems harbour unique chemicals and pharmaceuticals that can save people‘s lives数以千计的植物物种是生态系统的组成部分, 它们拥有独特的化学和药物功效, 可以挽救人们的生命;Ecosystem function and services生态系统功能和服务;Ecosystem function and services生态系统功能和服务;Provisioning Services
