宁夏银川市市区表层土壤重金属含量数据集

土壤中重金属的含量关系到生态系统健康，城市中土壤重金属将直接或间接地危害居民人体健康。2015年，以宁夏银川市市区为研究区，按照3 km x 3 km的格网布设采样点位置，实际采样时再对位置进行微调。取表层土壤，在室内自然风干，去除杂质等。利用X-荧光光谱仪(XRF)测定土壤样品中六种重金属（Co、Cr、Cs、Mg、Pb和Ti）的含量，得到宁夏银川市市区表层土壤重金属含量数据集。该数据集包括：（1）样点的地理位置数据；（2）表层土壤重金属含量数据。数据集存储为.kmz、.shp和.xls格式，数据量为73.8 KB，由8个数据文件组成（压缩为2个文件，18 KB）。该数据集的研究成果发表在《国外医学.医学地理分册》2017年38卷第4期上。

The concentration of heavy metals in soil is closely linked to ecosystem health, and heavy metals in urban soils can directly or indirectly jeopardize the health of residents. In 2015, the urban area of Yinchuan City, Ningxia Hui Autonomous Region was selected as the study area. Sampling points were initially laid out in a 3 km × 3 km grid, with minor adjustments made to their positions during actual sampling. Topsoil samples were collected, air-dried indoors, and impurities were removed. An X-ray fluorescence spectrometer (XRF) was used to determine the concentrations of six heavy metals (Co, Cr, Cs, Mg, Pb, and Ti) in the soil samples, thereby establishing the heavy metal concentration dataset of topsoil in the urban area of Yinchuan City, Ningxia. This dataset includes two parts: (1) geographic location data of sampling points; (2) heavy metal concentration data of topsoil. The dataset is stored in .kmz, .shp, and .xls formats, with an uncompressed total size of 73.8 KB. It consists of 8 individual data files, which are compressed into 2 files with a total size of 18 KB. The research outcomes based on this dataset were published in *Foreign Medical Sciences: Section of Medical Geography*, Volume 38, Issue 4, 2017.
