摘要
通过森林地上生物量(AGB)遥感产品验证获得全面、准确的遥感产品质量信息,是提高产品精度、改善产品质量的重要依据,也是正确使用产品、扩大产品应用范围的重要保障.随着探测森林生态系统结构参数的卫星数据逐步增加,未来将生产更多的森林AGB遥感产品,因此获得高精度的产品和高可信度的质量信息也将愈加重要.文中从参考数据的获取与质量控制流程,以及验证方法、指标、工具和报告等方面综述森林AGB遥感产品验证的研究进展,探讨需要重点加强的研究方向,为进一步提高森林AGB遥感产品验证的准确度和可靠性提供思路.
Abstract
Obtaining accurate quality information of forest aboveground biomass(AGB)remote sensing products through the validation is crucial for enhancing product accuracy and quality and for ensuring proper use of the products and expanding their scope of application.The increased number of satellites collecting data on forest ecosystem structure parameters leads to the emergence of more forest AGB products,and it is therefore increasingly vital to have high-precision products and reliable quality information.This paper reviews the research progress of the validation of forest AGB remote sensing products from the aspects of collection and quality control of reference data as well as validation's methods,indicators,tools and reports,and discusses key areas in the further research that need to be enhanced,with the aim to provide ideas for further improving the accuracy and reliability of the validation of forest AGB remote sensing products.
