中国环境背景值数据集(1970-1988年)

我国环境背景值研究是由研究土壤开始，逐渐扩展到水、生物、大气等其他要素。其研究过程大体分为三个阶段：一、1970年开始，中国科学院、某些地方环境单位及农业科研单位，先后开展了部分城市及部分地区的土壤及农作物的环境背景值调查研究。二、自982年开始，我国把环境背景值研究列入了国家重点科技攻关项目。组织了辽、吉、黑、湘、粤五省的环境监测，开展了松辽平原、湘江谷地的土壤环境，松花江水系、洞庭湖水系、珠江流域的北江水系，以及而江流域地下水环境背景值研究。此阶段不但获得了大量有价值、可比的30几个元素的背景值数据。三、自1986年起，全国环境背景值研究在960万平方公里的土地上展开，研究范围包括除台湾省以外的各个省份，分析元素达50余个。水环境背景值在整个长江流域展开，它标志着我国环境背景值研究进入了有计划、大规模、全面、系统的新阶段。本数据集整理了国内环境背景值领域数十年科学研究的成果，研究对象包括：土壤、水体、岩石、生物，背景元素包括：Cs、 Mg、 Fe 、Zn、 Mn、 Cu 、Ba、 Sr、 Mo 、Se 、Li、Be、Cr、Co、Ni、As、Zr、Pb、Cd、Hg、Fe等等。

Research on environmental background values in China initially focused on soil studies, and gradually expanded to other environmental media including water, organisms and the atmosphere. The overall research process can be divided into three stages:
1. Starting in 1970, the Chinese Academy of Sciences (CAS), local environmental institutions and agricultural research institutions successively carried out surveys and studies on environmental background values of soil and crops in certain cities and regions.
2. Starting in 1982, China included research on environmental background values into national key scientific and technological research projects. Environmental monitoring was organized in five provinces: Liaoning, Jilin, Heilongjiang, Hunan and Guangdong, and studies were conducted on soil environmental background values in the Songliao Plain and Xiangjiang River Valley, as well as groundwater environmental background values in the Songhua River system, Dongting Lake system, Beijiang River system of the Pearl River Basin and Xijiang River Basin. This stage yielded a large number of valuable and comparable background value data for more than 30 elements.
3. Starting in 1986, national-scale research on environmental background values was carried out across China's 9.6 million square kilometers of territory, covering all provinces except Taiwan Province, with more than 50 elements analyzed. Water environmental background value studies were conducted across the entire Yangtze River Basin, which marked that China's research on environmental background values has entered a new stage of planned, large-scale, comprehensive and systematic development.

This dataset collates the results of decades of scientific research in the field of domestic environmental background values. The research objects include soil, water, rock and organisms, while the background elements include Cs, Mg, Fe, Zn, Mn, Cu, Ba, Sr, Mo, Se, Li, Be, Cr, Co, Ni, As, Zr, Pb, Cd, Hg, Fe, etc.
