Land-cover is an indispensable basic information for climate change research, ecological environment assessment and geographical situation monitoring. In recent years, with the continuous improvement of Remote Sensing Science and technology and computer storage and computing capacity, the application demand of long time-series global 30m land-cover dynamic monitoring products is becoming more and more urgent. To achieve the goal of automatically monitoring long time-series global 30-m land-cover dynamics, we used our newly global 30-m land-cover products with fine classification system in 2020 (GLC_FCS30-2020) as the benchmark reference dataset, and then proposed a novel and automatic land-cover monitoring strategy by coupling with continuous land-cover change detection models with the dynamic updating algorithms, and finally produced the time-series global 30-m land-cover dynamic monitoring products (every 5-years) using the continuous time-series Landsat imagery. It should be noted that our global land-cover dynamic monitoring products inherited the classification system of GLC_FCS30-2020, containing 29 land-cover types.

土地覆盖（Land-cover）是气候变化研究、生态环境评估及地理国情监测不可或缺的基础信息。
近年来，随着遥感科学与技术、计算机存储及计算能力的持续提升，长时间序列全球30米土地覆盖动态监测产品的应用需求日益迫切。为实现长时间序列全球30米土地覆盖动态自动监测的目标，我们以新研发的2020年全球30米精细分类系统土地覆盖产品（GLC_FCS30-2020）作为基准参考数据集，提出了一种新颖的自动化土地覆盖监测策略——将连续土地覆盖变化检测模型与动态更新算法相耦合，最终利用连续时间序列Landsat影像生成了每5年一期的时间序列全球30米土地覆盖动态监测产品。需注意的是，我们的全球土地覆盖动态监测产品继承了GLC_FCS30-2020的分类体系，包含29种土地覆盖类型。
