青藏高原农业活动强度数据集（1980s-2015）

青藏高原农业活动强度数据集是基于县级农业统计数据，包括逐年耕地面积、农林牧渔劳动力、农机总动力、农村用电量、有效灌溉面积、农药使用量、化肥使用量、粮食作物总产量、农林牧渔生产总值，构建以农业投入指数和产出指数为一级指标，单位耕地面积农机总动力、单位耕地面积化肥施用量、劳动生产率等10个指标为二级指标的农业活动强度指标体系。利用熵值法确定各级指标权重，并通过层次分析法获得青藏高原县级农业投入和产出指数。基础数据来自国家统计局发布的统计数据，并对原始数据进行了核准与校正，具有较高可信度。数据集包括的1980s-2015年青藏高原县级投入产出指标和投入、产出指数一定程度上反映了青藏高原农业生产活动强度时空变化特征，为当地农业发展提供数据支持和理论参考。

This dataset of Agricultural Activity Intensity on the Qinghai-Tibet Plateau is constructed based on county-level agricultural statistical data, including annual cultivated land area, labor force for agriculture, forestry, animal husbandry and fishery, total agricultural machinery power, rural electricity consumption, effective irrigated area, pesticide application amount, fertilizer application amount, total grain crop output, and gross output value of agriculture, forestry, animal husbandry and fishery. An agricultural activity intensity index system is established, with agricultural input index and agricultural output index as its first-level indicators, and 10 second-level indicators such as total agricultural machinery power per unit cultivated land, fertilizer application amount per unit cultivated land, labor productivity, etc. The entropy weight method is used to determine the weights of indicators at all levels, and the analytic hierarchy process (AHP) is applied to calculate the county-level agricultural input and output indices of the Qinghai-Tibet Plateau. The underlying data are sourced from official statistics released by the National Bureau of Statistics, and the original data have been verified and corrected, with high reliability. The county-level input-output indicators, input indices and output indices of the Qinghai-Tibet Plateau from the 1980s to 2015 included in this dataset reflect, to a certain extent, the spatiotemporal variation characteristics of agricultural production activity intensity on the Qinghai-Tibet Plateau, and provide data support and theoretical references for local agricultural development.
