摘要

本文报道了使用过剩

210

Pb含量在泥芯样中的垂直分布计算得出江西省鄱阳湖底泥的近代沉积速率。由于湖区各部位地理、地貌、水文等条件的差异，故湖区各测点的沉积速率也不同。全湖以湖心区的沉积速率最低：三个测点中有二个因沉积率太低未能检出，另一测点的沉积率为0.14 cm/a。其次是东北湖湾区，平均沉积率是0.19cm/a。入湖扩散区为入鄱阳湖的五河泥沙的主要淤积区域，且该区地理水文等因素差异甚大，因此，沉积率变幅也较大，其值为0.08—0.28cm/a。入江水道区的湖湾部分，由于长江泥沙淤积之故，其沉积率为全湖所有测点中最高，其值分别为0.23 cm/a和0.62cm/a。

Abstract

The ediment accumulation rates were estimated from the vertical distribution of excess

Pb measured in sediment cores collected from Lake Poyang

Jiangxi. These rates were various with the difference in hydrology. The sedimentation rates are the lowest in the middle region of the lake

in which two samples could not be determined and the other one is 0.14 cm/a. The sedimentation rates are lower in the northeast basin section

averaging 0.19 cm/a. In the diffusion area of the lake from which 5 rivers enter sand deposion is more than in other areas of the lake and the hydrology factors are various

the sedimentation rate variation is lager. They are from 0.08 cm/a to 0.28 cm/a. Because of the and from the Yangzhi River the sedimentation rates are the highest in the water-way section of the lake

averaging from 0.23 cm/a to 0.62 cm/a.
