黄土高原县域固定资产投资发展指标可视化数据集（1980-2019年）

数据集为黄土高原县域固定资产投资发展指标可视化数据。数据内容包括黄土高原县域全社会固定资产投资、新增固定资产、住宅开发投资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 provides visualization data for county-level fixed asset investment development indicators in the Loess Plateau. The data covers 6 indicators including total social fixed asset investment, newly increased fixed asset investment, and residential development investment, with 40 spatial layers spanning the period from 1980 to 2019. All data was vectorized using ArcGIS software based on the statistical yearbooks of prefecture-level cities across the Loess Plateau. The data production workflow first digitizes the indicator data extracted from the statistical yearbooks, then assigns the digitized values to the vector graphic datasets via spatial join operations to generate the final products. The original spatial vector graphic data has a precision scale of 1:1,000,000, and the post-processing precision is not lower than that of the raw data. Due to missing data entries in certain years from the source statistical yearbooks, some year-specific records in the map layers contain null values. This dataset is applicable to social and economic research, ecological change research and other relevant studies in the Yellow River Basin.
