摘要:
依托收集的耕地土壤重金属污染案例资料，建立了我国138个典型区域的耕地土壤重金属污染数据库，并利用《土壤环境质量标准》（GB15618—1995）中的二级标准作为评价标准，测算了我国耕地的土壤重金属污染概况。研究表明：（1）我国耕地的土壤重金属污染概率为16.67%左右，据此推断我国耕地重金属污染的面积占耕地总量的1/6左右；（2）耕地土壤重金属污染等别中，尚清洁、清洁、轻污染、中污染、重污染比重分别为68.12%，15.22%，14.49%，1.45%，0.72%；（3）8种土壤重金属元素中，Cd污染概率为25.20%，远超过其他几种土壤重金属元素；此外，也有一些区域发生Ni，Hg，As和Pb土壤污染，但是Zn、Cr和Cu元素发生污染的概率较小；（4）辽宁、河北、江苏、广东、山西、湖南、河南、贵州、陕西、云南、重庆、新疆、四川和广西14个省、市和自治区可能是我国耕地重金属污染的多发区域，特别是辽宁和山西的耕地土壤重金属污染可能尤其严重。
Abstract:
Based on the data collected from documents, a database of heavy metal pollution, involving in 138 of regions, in soils of cultivated land in China, was established to calculate the degree of heavy metal pollution of cultivated land in China according to the second grade value from the Standard of Soil Environmental Quality (No.GB15618—1995). The following conclusions can be drawn as: (1) the probability of heavy metal pollution in soils of cultivated in China was about 16.67%, implying that 1/6 of cultivated land in China may suffer from heavy metal pollution; (2) the proportions of pollution degrees ranked as clean, relative clean, light pollution, moderate pollution and severe pollution were 68.12%, 15.22%, 14.49%, 1.45% and 0.72% of the total area of cultivated land, respectively; (3) the pollution probability of Cd was about 25.20%, significantly exceeding pollution levels of the other heavy metals. Moreover, the heavy metal pollution of As and Pb occurred occasionally in cultivated land in China but pollution of Zn, Cr and Cu seldom happened; (4) cultivated lands in Liaoning, Hebei, Jiangsu, Guangdong, Shanxi, Hunan, Henan, Guizhou, Shaanxi, Yunnan, Chongqing, Xinjiang, Sichuan and Guangxi, especially for Liaoning and Shanxi, may be the key regions of heavy metal pollution.
