Phosphorus cycling in antimony area

To disclose the composition and diversity of native microbiomes in mining environments and clarify they adapt to different gradients of heavy metal pollution, we selected the worlds largest Sb mining area (XKS, Hunan, China) as our study area. From the central mining area to the adjacent area at different distances, we randomly collected soil samples from 30 sites to cover different levels of Sb contamination. Soil cores collected were separated into six sections (i.e., 0-5, 5-10, 10-20, 20-30, 30-40, 40-50 cm).

为探明矿山环境中本土微生物群落的组成与多样性，并阐明其对不同梯度重金属污染的适应机制，本研究选取全球最大的锑（Sb）矿区——中国湖南XKS矿区作为研究区域。从矿区中心向不同距离的周边区域，随机采集30个点位的土壤样本，以覆盖不同水平的锑污染程度。所采集的土壤柱样被划分为6个深度分层：0~5 cm、5~10 cm、10~20 cm、20~30 cm、30~40 cm及40~50 cm。
