| 摘 要： | 全球地表覆盖分布及变化是气候变化研究、生态环境评估、地理国情监测、宏观调控分析等不可或缺的重要基础信息.国际上现有全球五套地表覆盖数据产品的空间分辨率为1 km或300 m,数据精度、分类体系、时空分辨率等均存在不足.为了满足全球变化研究与地球模式模拟的需求,应该研制具有较高时空分辨率、更符合全球变化需要、精度较好的全...

| Abstract: | Global land cover data is fundamental for many application areas,especially for climate change and global sustainability studies.Several global land cover data products at 1 km or 300 m spatial resolution have arisen from different national or international initiatives.With a focus on mapping different vegetation types worldwide,they were developed with coarse-resolution remote sensing data and using different mapping approaches.The inconsistencies and uncertainty of these data products have been studied an... |
