我国滇池流域1997-2017年20种重金属在沉积物中的含量分布数据整编

收集整编了1997-2017年内，国内外针对滇池流域内沉积物中重金属含量的文献调查与记录数据，数据包括含有一级流域名称、二级流域名称、地表水名称、采样区域、采样地点、点位名称、点位坐标（经度，纬度）、采样时间、采样水期（丰水期、平水期、枯水期）、采样项（水）、沉积物采样层次|单位、污染物名称、浓度值（最大值、最小值、平均值）|单位、标准偏差、分析信息备注、文献名称，数据来源具体信息、数据整编时间、数据整编单位、数据共享或使用限制、整编人员、审核人员等。

This dataset compiles literature surveys and recorded data regarding heavy metal concentrations in sediments within the Dianchi Lake Basin, sourced from domestic and international publications over the period 1997 to 2017. The collected data includes: first-level basin name, second-level basin name, surface water body name, sampling area, sampling site, sampling point name, point coordinates (longitude, latitude), sampling time, sampling hydrological period (high flow, normal flow, low flow), sampling item (water), sediment sampling layer and corresponding unit, pollutant name, concentration values (maximum, minimum, average) and corresponding unit, standard deviation, analysis notes, literature reference, detailed data source information, data compilation time, data compilation organization, data sharing or usage restrictions, compilation personnel, review personnel, and other relevant information.
