摘要: 面对生态退化风险,我国草地资源迫切需要现代遥感技术建立规范化遥感解译框架来支撑草地新时期的调查与管理。本研究通过对文献分析和历史资料的整理,梳理我国草地资源调查工作历程,分析草地资源调查技术的进展与不足。在此基础上,结合遥感标准光谱端元空间的优势,勾画草地资源类型学-草地资源调查-管理之间的关联与尺度效应,提出多尺度融合嵌套的草地资源遥感解译框架,并建议推动草地系统知识共享平台的搭建,为草地资源适应性管理研究与实践提供重要支撑。

Abstract: Facing the increasing risk of ecological degradation, it is urgent to establish a standardized framework of remote-sensing image interpretation to conduct grassland investigation and management. This study summarized the history of grassland resource investigation and analyzed the development of investigation technology in China through literature collection and historical data collation. Taking advantage of spectral endmember space, the correlation and scale effect among grassland resource typology, investigation, and management were established. We also proposed an interpretation framework of spectral endmember space based on a multiscale fusion strategy for grassland and made a suggestion of a sharing platform of grassland systematic knowledge, which would provide a support for the researches of management and other practices of grassland resources.

Key words: Grassland resources, Investigation history, Spectral endmember space, Interpretation framework, Sharing platform
