摘要
根据1997～1999年现场调查资料,分析了太湖污染淤泥平面和垂直分布特征,估算了太湖各湖区及不同泥厚的底泥淤积面积和蓄积量。结果表明:全湖有69.83％面积为污染淤泥所覆盖,厚度最大达5m以上,底泥总蓄积量为19.15亿m^3,全湖平均底泥厚度为0.82m。淤泥分布湖西部较湖东部分布区域大,且泥层较厚;湖心区底泥分布少且薄;近80％的底泥分布在2m厚度以内。研究还表明:湖流作用、入湖河道位置和古河道分布是太湖底泥分布的主要影响因素。
Based on sludge investigating data collected in 1997 ~ 1999 in Lake Taihu, to analyze plane and vertical distributing characteristics of lake bottom sludge and calculate the accumulating areas and volumes at the different regions. The results showed that about 69.83% of the whole lake is covered with sludge. The total storage is up to 1.915× 109m3 and average thickness is 0.82m. Several obvious features were obtained in the results. Area of sludge in the west part is larger and thicker than the east, and that of the central part is less and thinner, about 80% of sludge is distributed within 2m thickness. It was discovered that lake current, the position of the rivers entering lake and distribution of the ancient rivers are the main factors of sludge distribution in Lake Taihu.
