青藏高原农作物秸秆资源量历史数据集（1996-2018）

本数据来自1996年到2018年间西藏、青海、四川、云南、甘肃官方统计年鉴以及相关农业统计公报的秸秆资源量，青藏高原统计范围为西藏自治区和青海省全部地级市，甘肃省为甘南州，云南省为迪庆州，四川省为阿坝藏族羌族自治州、甘孜藏族自治州、凉山彝族自治州。该数据集主要包括青藏高原每个地区小麦秸秆、水稻秸秆、青稞秸秆和玉米秸秆资源量数据，单位为万吨。农作物秸秆资源量通常是根据农作物产量和草谷比系数进行估算，即秸秆资源量＝农作物产量×草谷比系数。数据表格中0值或者空值代表该地区未统计此类数据。

This dataset is compiled from straw resource quantity data sourced from official statistical yearbooks and relevant agricultural statistical bulletins of the Tibet Autonomous Region, Qinghai Province, Sichuan Province, Yunnan Province and Gansu Province between 1996 and 2018. The statistical scope for the Qinghai-Tibet Plateau includes all prefecture-level cities within the Tibet Autonomous Region and Qinghai Province; for Gansu Province, the scope covers Gannan Tibetan Autonomous Prefecture; for Yunnan Province, it refers to Diqing Tibetan Autonomous Prefecture; for Sichuan Province, it includes Aba Tibetan and Qiang Autonomous Prefecture, Garze Tibetan Autonomous Prefecture and Liangshan Yi Autonomous Prefecture. This dataset mainly contains straw resource quantity data of wheat, rice, highland barley and corn in each region of the Qinghai-Tibet Plateau, with the unit of ten thousand tons. Crop straw resource quantity is usually estimated based on crop yield and the straw-to-grain ratio coefficient, i.e., straw resource quantity = crop yield × straw-to-grain ratio coefficient. Zero values or null values in the data table indicate that such data were not statistically recorded for the corresponding region.
