2015-2020年我国1:1500万稻谷重金属含量空间分布图

2015-2020年我国1:1500万稻谷重金属含量空间分布图，以重金属种类为单位分组分别制图，记录全国主产区稻谷采样点分布的空间位置、8种重金属的含量等信息。数据包括：样点编号、采样日期、地理信息、镉总量、铅总量、汞总量、砷总量、铬总量、镍总量、铜总量、锌总量。共形成8个图集。

Spatial distribution maps of heavy metal concentrations in rice at a scale of 1:15 million across China, covering the period from 2015 to 2020. These maps are grouped and produced individually by heavy metal type. The dataset documents the spatial locations of rice sampling points in major national grain production areas, alongside the concentrations of 8 heavy metals at these sampling sites. The dataset contains the following entries: sample ID, sampling date, geographic information, total cadmium, total lead, total mercury, total arsenic, total chromium, total nickel, total copper, and total zinc. A total of 8 thematic atlases are created, with one atlas per heavy metal type.
