黄土高原县域贸易、旅游发展指标可视化数据集（1980-2019年）

数据集为黄土高原县域贸易、旅游发展指标可视化数据。数据内容包括黄土高原县域社会消费品零售总额、城镇社会消费品零售总额、进出口总额、居等6个指标，包括1980-2019年40个图层，数据是根据黄土高原各地市统计年鉴在ARCGIS软件矢量化形成。数据生产过程首先进行年鉴数据指标数字化，通过空间连接的方法赋值到矢量图形数据，形成结果。空间矢量图形数据精度为1:100万，经过处理后精度不低于原始数据。由于统计年鉴中有些年份数据缺项，造成图件某些年份数据是空值。数据应用为黄河流域社会经济研究、生态变化研究等。

This dataset comprises visualized data of county-level trade and tourism development indicators for the Loess Plateau. It includes a total of 6 indicators: county-level total retail sales of social consumer goods, urban total retail sales of social consumer goods, total import and export volume, and residential-related indicators, with 40 spatial layers spanning the period from 1980 to 2019. This dataset was generated via vectorization in ArcGIS software, using statistical yearbooks of prefecture-level cities across the Loess Plateau as the data source. The data production workflow first involves digitizing the indicator data extracted from the statistical yearbooks, then assigning the digitized values to the vector graphic datasets through spatial join operations to produce the final dataset. The spatial vector graphic data has a map scale of 1:1,000,000, and the accuracy of the processed data is no lower than that of the original source data. Due to missing data entries in certain years across the statistical yearbooks, the attribute values of the map layers for corresponding years are null. This dataset is applicable to socio-economic research, ecological change research and other related studies in the Yellow River Basin.
