摘要 为改善平阴县生态环境,为农业区划、环境保护和地方病防治等领域提供全新的地球化学资料
和科学依据,开展了平阴县生态地球化学调查。调查发现,平阴县周边及其西部农田区有As、Ni、
Cd、Cr、F、Cu、Mn、S、Hg等以重金属为主的元素异常,平阴县周边元素异常具有异常衬度较高、
富集系数大等特征,西部农田区异常具有各元素套合关系好、多数异常衬度不高、富集系数小的特
点。研究结果表明,西部农田区异常以As、Cd为主要成分,元素含量与SiO2,Al2O3,Fe
2O3等常量组分间具有显著的相关性,随SiO2含量的增加而降低,随Al2O3,Fe2O3含
量的增加而增加,说明土壤常量组分及其所决定的土壤质地是导致异常形成的主要因素;而平阴城
区异常以S、Hg、As、Zn、Mn等元素为主,是典型的受人类综合污染而产生的异常。
Abstract ::In order to improve the ecological environment of Pingyin County and provide geochemical
data and scientific basis for agricultural division, environmental protection and local disease
prevention and control, the authors carried out ecological geochemical survey in Pingyin County. The
results show that Pingyin County area and its west farmland have such anomalies as As, Ni, Cd, Cr, F,
Cu, Mn, S and Hg, with the main elements being heavy metals. In Pingyin area, the soil anomalies are
characterized by low anomalous contrast and low concentration coefficients, whereas in west
farmland, the main anomaly components are As and Cd, and the element content is remarkably
related to major elements of SiO2,Al2O3,Fe2O3, being negatively related to SiO2, and positively
related to Al2O3 and Fe2O3. All these characteristics suggest that the major elements in soil and the
soil texture are main factors causing anomalies. In contrast, the anomalies in Pingyin County are
mainly anomalies of S, Hg, As, Zn and Mn, which are evidently caused by human composite pollutions
like industrial soot, industrial sewage and domestic waste.
