浙江杭嘉湖平原区环境地球化学研究

ENVIRONMENTAL GEOCHEMICAL STUDY OF HANGZHOU-JIAXING-HUZHOU PLAIN,ZHEJIANG PROVINCE

根据杭嘉湖平原区区域地球化学调查结果，对本区开展了区域和城市（杭州市）环境质量评价的环境地球化学研究。研究结果表明，杭嘉湖平原区区域环境质量和杭州市区环境质量良好，各环境质量区较好的反映各区内工业生产水平、人口密集程度、历史长短。通过对杭州市不同环境质量区内蔬菜的分析研究证明，杭州市区污染区内有害元素尚未对人体健康产生影响，但为防止今后出现超标现象，应当高度重视，加强土壤环境保护。

Based on achievements gained in regional geochemical investigation conducted in Hangzhou-Jiaxing Huzhou plain, the authors carried out environmental geochemical research for the purpose of evaluating regional andcity (Hangzhou) environmental quality. The results show that regional environmrnt quality of this area and urbanenvironmental quality of Hangzhou City are good, and that various environmental quality districts quite satisfactorilyreflect their industrial production levels, population densities and history. Analytical study of vegetables from different environmental quality districts of Hangzhou City has proved that harmful elements in the polluted district ofHangzhou City have not yet affected human healty; nevertheless, importance should be attached to soil environmental protection to prevent harmful elements from exceeding standards.
