全球0.5°×0.5°分辨率草地空间分布数据集（1911-2010年）

该数据集是基于综合顺序分类法的全球草地空间分布数据，将过去100年(1911-2010年) 划分为4个时期，每30年为一个时期。数据基于CRU提供的气温和降水数据，经过计算，生成1920s(1911-1940年)、1950s(1941-1970年)、1970s(1961-1990年)和1990s (1981-2010年)4个时期的全球草地生态系统空间分布图(grass)及同时期的年均气温(mean_t)和年均降水(prep)数据，草地分类数据图例：1.冻原与高山草地类组（Tundra & alpine Steppe）；3. 典型草地类组（Typical grassland）；4.热带稀树草原类组（Tropical Savanna）；6.荒漠草地类组（Desert grassland）；7.温带湿润草地类组（Temperate humid grassland），数据格式为TIFF。本数据集地理空间范围是全球陆地，不含南极大陆等区域。

This dataset is global spatial distribution data of grasslands based on the Comprehensive Sequential Classification Method. It divides the past 100 years (1911–2010) into four 30-year periods. Using air temperature and precipitation data provided by the Climatic Research Unit (CRU), it generates spatial distribution maps of global grassland ecosystems (grass) for four periods: the 1920s (1911–1940), 1950s (1941–1970), 1970s (1961–1990), and 1990s (1981–2010), alongside corresponding annual mean air temperature (mean_t) and annual mean precipitation (prep) data for each period. Legend for grassland classification data: 1. Tundra & Alpine Steppe; 3. Typical Grassland; 4. Tropical Savanna; 6. Desert Grassland; 7. Temperate Humid Grassland. All data are stored in TIFF format. The spatial scope of this dataset covers global terrestrial areas, excluding regions such as the Antarctic continent.
