摘　　要：生态状况的退化引起了人们的广泛关注,推动了定量分析生态质量方法的发展,加速了生态质量概念的完善,从而有利于指导未来生态环境保护政策的制定。基于当前生态系统功能和生物多样性生境的像素级历史基线的生态质量概念框架,应用卫星遥感和生态系统过程模型数据,经过正向归一化、相关性分析、基于粒子群优化的投影寻踪算法方面的数据质量控制,构建了2000–2018年空间分辨率为1公里的中国陆地生态系统生态质量数据集。通过共享本数据集,以期为生态评估理论和方法的发展,以及为宏观生态系统的管理和决策提供数据基础。The deteriorating ecological conditions have attracted widespread attention,spurring the development of quantitative analysis methods for ecological quality,improving the concept of ecological quality,and thus facilitating the formulation of future ecological environmental protection policies.Using satellite remote sensing and ecosystem process model data,we constructed a conceptual framework for ecological quality based on a pixel-level historical baseline of current ecosystem functions and biodiversity habitats through data quality control in forward normalization,correlation analysis,and projection pursuit algorithm based on particle swarm optimization,resulting in dataset of ecological quality indexes of terrestrial ecosystems in China from 2000 to 2018 with a spatial resolution of 1 km.By sharing this dataset,we aim to provide a data foundation for the advancement of ecological assessment theories and methods,as well as the management and decision-making of macro ecosystems.
