摘要
在福建省沿海经济带生态地球化学调查基础上,根据地质背景和地貌类型、土壤酸碱度和SiO2含量,将调查区划分为36个生态地球化学区,归纳了各区特征性的化学元素种类。为了正确评价各生态地球化学区的质量,分析了福建省历史文化名镇(村)的地质背景,探讨了滨海地区土壤有机质含量和稻米汞含量的关系。结果表明,海峡西岸生态环境质量良好,花岗岩低山丘陵区特别优良,重金属元素异常主要分布在河口平原,而在滨海沙地有害元素的生物有效性高。
Based on the results of the eco-geochemical survey of economic regions along the coast of Fujian Province, geological setting, geomorphic types, soil reaction and SiO2 content, the surveying area can be divided into 36 eco-geochemical zones. The characteristic chemical elements of the eco-geochemical zones are also under the summing-up in the paper. In order to appreciate the quality of eco-geochemical zones, the author made an assay of the geological background of well-known historical and cultural towns or villages in Fujian Province and probed into the relations between the contents of soil organic matters and the mercury contents in rice corn along the offshore areas. It is shown that the ecological environment in the west bank of Taiwan Strait is all right, especially in low mountain rolling granite country. The anomaly of heavy metal elements is mostly distributed over the estuary plain and the biological effectiveness of harmful elements in sandy ground near sea is higher in Fujian Province.
