摘要
概述了南洞庭湖湿地的基本情况,对湖区湿地生态退化进行了分析,认为湿地存在泥沙淤积严重、自然湿地面积减少、生物多样性降低、水质污染加剧、湿地功能衰退等生态问题,并对退化原因进行初步分析,认为人为因素是南洞庭湖湿地生态退化的主要原因.
This paper summarized the basic circumstance of wetlands in the South Dongting Lake, and then analyzed ecological degeneration. It considered that mud filled up seriously, acreage of natural wetlands reduced, biology diversity depressed, water pollution pricked up, wetlands function declined, and so on. This paper gave out the reason of degeneration and acknowledged that artificial factor was the main reason to the degeneration of South Dongting Lake wetlands.
