Data from Multidimensional responses of grassland stability to eutrophication

The files contain cover and biomass data under ambient and nutrient addition (by NPK; up to 15 years) conditions at 55 NutNet sites (https://nutnet.org/), geolocations and growing seasons, and precipitation and potential evapotranspiration (1901 - 2021) at these 55 sites. Precipitation and potential evapotranspiration are used to calculate the standardized precipitation–evapotranspiration index (SPEI), these data were downloaded from https://crudata.uea.ac.uk/cru/data/hrg/cru_ts_4.06/.本数据集包含55个NutNet（全球养分添加实验网络，https://nutnet.org/）站点在原位环境与NPK养分添加（实验时长最长达15年）条件下的植被盖度与生物量数据、各站点的地理位置与生长季信息，以及1901年至2021年的降水量与潜在蒸散量数据。上述降水量与潜在蒸散量可用于计算标准化降水蒸散指数（SPEI），原始数据下载自https://crudata.uea.ac.uk/cru/data/hrg/cru_ts_4.06/。
