2015-2020年1:1500万我国大豆重金属含量空间分布图

2015-2020年1:1500万我国大豆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，记录全国主产区大豆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。

This dataset contains spatial distribution maps of heavy metal concentrations in soybeans across China at a scale of 1:15,000,000, spanning the years 2015 to 2020. The maps were grouped and generated separately by heavy metal category, and record the spatial locations of soybean sampling sites in major domestic production areas, along with the concentrations of 8 heavy metals and other associated metadata. The specific data items include: sample ID, sampling date, geographic information, total cadmium (Cd), total lead (Pb), total mercury (Hg), total arsenic (As), total chromium (Cr), total nickel (Ni), total copper (Cu), and total zinc (Zn). A total of 8 thematic atlases were compiled from this dataset.
