该数据集是公元前 10000 年至公元 2100 年的 1 千米全球耕地数据集。它包含从过去到未来共计 131 幅 1 千米分辨率的全球耕地地图。公元前 10000 年至公元前 2100 年的时间间隔为 1000 年，公元前 1 年至公元前 1700 年的时间间隔为 100 年，公元前 1700 年至公元前 2100 年的时间间隔为 10 年。公元 2010 年之后，提供了八种未来 SSP-RCP 情景。地图数值表示 1×1 千米网格单元内的耕地比例。", "ds_source": "

This dataset is a 1-kilometer global farmland dataset from 10000 BC to 2100 AD. It contains a total of 131 global farmland maps with a resolution of 1 kilometer from the past to the future. The time interval between 10000 BC and 2100 BC is 1000 years, the time interval between 1 BC and 1700 BC is 100 years, and the time interval between 1700 BC and 2100 BC is 10 years. After 2010 AD, eight future SSP-RCP scenarios were provided. The map values represent the proportion of cultivated land within a 1 × 1 kilometer grid cell.
