<strong>Abstract</strong> This dataset has been collected to check the predictability of forage quality of alpine grasslands from remotely sensed data. We investigated this relationship in the Gran Paradiso National Park (Western Italian Alps). In 2012 we collected a total of 142 grass samples within 19 experimental plots every two weeks during the whole growing season. From these samples we estimated biomass, relative and available crude protein, fiber (neutral detergent, acid detergent and lignin) and fiber digestibility (at 24 and 240 hours).Data were used in the following publication: L. Ranghetti, B. Bassano, G. Bogliani, A. Palmonari, A. Formigoni, L. Stendardi and A. von Hardenberg (2016). «MODIS time series contribution for the estimation of nutritional properties of alpine grassland».

**摘要** 本数据集旨在验证利用遥感数据预测高山草地饲草品质的可行性。研究以意大利西部阿尔卑斯山的格兰帕拉迪索国家公园为研究区,探究了遥感数据与饲草品质之间的关联关系。2012年,在整个生长季内,研究人员每两周于19个实验样地中采集共计142份草样。通过对这些草样的分析,我们测定了以下指标:地上生物量、相对粗蛋白与可利用粗蛋白、纤维类成分(中性洗涤纤维、酸性洗涤纤维与木质素)以及纤维消化率(分别测定24小时与240小时条件下的消化率)。本数据集已应用于以下发表论文:L. Ranghetti、B. Bassano、G. Bogliani、A. Palmonari、A. Formigoni、L. Stendardi及A. von Hardenberg(2016),《MODIS时间序列对高山草地营养属性的估算贡献》,《欧洲遥感期刊》,第49卷:691-718,DOI: http://dx.doi.org/10.5721/EuJRS20164936。 **数据结构** 1. field2012.csv - int_id:整数型,记录编号(序列号) - text_id:因子型,共142个水平,记录编号(字符串格式) - group:因子型,共18个水平,采样组编号(代表重复次数) - doy:整数型,采样日期的年积日 - plot:因子型,共19个水平,样地名称(与plot.2012$plot中的样地名称匹配) - AB:数值型,地上生物量(单位:克) - H2O:数值型,含水量(地上生物量与鲜重的比值) - CP:数值型,粗蛋白含量(占总重量的百分比) - NDF:数值型,中性洗涤纤维含量(占总重量的百分比) - ADF:数值型,酸性洗涤纤维含量(占总重量的百分比) - ADL:数值型,木质素含量(占总重量的百分比) - dNDF24:数值型,24小时中性洗涤纤维消化率(占中性洗涤纤维的百分比) - dNDF240:数值型,240小时中性洗涤纤维消化率(占中性洗涤纤维的百分比) 2. field2012_heights.csv - int_id:整数型,记录编号(序列号) - text_id:因子型,共142个水平,记录编号(字符串格式) - group:因子型,共18个水平,采样组编号(代表重复次数) - doy:整数型,采样日期的年积日 - plot:因子型,共19个水平,样地名称(与plot.2012$plot中的样地名称匹配) - h_tot:数值型,总生物量平均高度(单位:厘米) - h_green:数值型,绿色生物量平均高度(单位:厘米) 3. plots2012.dbf - plot:因子型,共19个水平,用于标识单个样地的字符串编码 - elevation:整数型,样地海拔高程,源自Tinitaly 10米分辨率数字高程模型(DEM)(详见正文) - aspect:整数型,样地坡向,由高程地图提取得到 - Localita:因子型,共19个水平,样地的描述性位置(意大利语标注)
