摘　　要：洞庭湖湿地作为中国重要的湖泊湿地,受区域和流域内地质、地球化学背景、地理条件、工农业生产及人类生活等因素的综合影响,区内环境地球化学问题非常突出,主要表现在:洪涝灾害频繁、水体污染严重、土壤退化明显、酸雨危害加剧等方面。这些一方面导致生物多样性降低、另一方面对人类的生存造成了很大的威胁。为了保护洞庭湖区的湿地资源并加以合理利用,必须进行有效的湿地区域生态地球化学调查,作出合理的分类评价,治理湿地污染,在此基础上进行湿地资源利用与保护规划。The Dongting lake is an important lake wetland in China. Due to the comprehensive influence of geology, geochemical background, geographical condition, industrial and agricultural production, human being activities etc., the environmental geochemical problems in the area are becoming more and more serious, such as frequent flood and waterlogging calamity, severe water pollution, soil degeneration, acid rainfall, etc. These problems have resulted in reduction of biological diversity and threatened the living of human being. In order to protect and reasonably utilize wetland resources of the Dongting lake, the effective regional ecological and geochemical investigation must be carried out to make out reasonable classification evaluation and wetland pollution control, and on the base of these work, to make utilization and protection plan of wetland resources.
