摘要
生态质量是指一定时空范围内生态系统要素、结构和功能的综合特征,具体表现为生态系统的状况、生产能力、结构和功能的稳定性、抗干扰和恢复能力。生态系统的质量是我国生态文明建设和生态环境监测的重要内容,多时空尺度观测技术的发展为生态系统质量监测与评价提供了新机遇,但同时也对国家尺度生态要素、生物多样性和生态功能的观测标准与技术规范提出了新的要求。本国家重点研发项目自2017年7月立项以来,围绕国家尺度生态质量监测技术与规范,开展了生态系统网络观测技术规范、台站生态要素监测、区域生物多样性和区域生态功能监测技术与规范的研究,在典型农林草湿地生态系统开展应用示范。项目在生态质量综合监测指标体系构建、生态系统研究网络观测技术、区域生物多样性和区域生态功能监测、基于无人机和机器学习的荒漠植被监测等方面取得了重要进展,促进了生态质量监测技术的发展。我们组织本专辑从不同视野集中系统介绍本项目已取得的生态质量监测技术和评价方法,以期促进生态学及其观测技术的发展。
Ecological quality is defined as the stability, adaptability and resilience of an ecosystem. Monitoring and assessing ecological quality are important bases for China's ecological civilization construction. The national key research and development program "Technologies and guidelines for monitoring ecological quality of terrestrial ecosystems in China", launched in July 2017, includes plans to study the observation technologies and provide guidelines on the ecological in-situ observation, the regional biodiversity and ecosystem function monitoring and its applications, all of which contribute to national ecological quality assessment. A year after its implementation,some important progress has been achieved, such as building the indicator system for comprehensive monitoring of ecological quality and improvement of the methods, mass data transmission, infrared camera-based monitoring of biodiversity, multi-angle automatic spectral observation systems, and unmanned aerial vehicle(UAV) based desert monitoring. We have organized this special issue and attempted to introduce the monitoring techniques and assessment methods on ecological quality from different perspectives in order to further promote the development of ecology and its observation methods.
