2015-2020年我国1:1500万小麦重金属含量空间分布图

2015-2020年我国1:1500万小麦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，记录全国主产区小麦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 wheat at a scale of 1:15,000,000 across China from 2015 to 2020. The maps were separately grouped and produced based on heavy metal types, recording the spatial positions of wheat sampling points in major national wheat production areas, the concentrations of 8 heavy metals, and other relevant information. The dataset includes: sampling point 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 atlases were generated.
