- 鄱阳湖及周边经济区土壤镉的含量与分布
- 作者： 程钊 江俊杰 李丹 赖劲虎 吴代赦 来源：地球与环境 年份：2015 文献类型 ：期刊 关键词： 分布 鄱阳湖 镉 土壤
- 描述：采用双层网格布点法,在研究区分别采集表层和深层土壤样品9829和2467个,测定了样品的镉含量和pH值。表层土壤镉含量呈对数正态分布,含镉范围0.024~4.619mg/kg,宜用几何平均值0.157mg/kg表征其平均含量。深层土壤镉含量显著低于表层,含量范围0.010~1.982mg/kg,算术平均值和几何平均值分别为0.098mg/kg和0.080mg/kg。研究区7地市表层土壤镉含量几何平均值较30年前上升34.6%~165%。据《土壤环境质量标准GB15618-1995》,以镉为评价指标时,研究区以Ⅰ类土壤为主,分布面积占总面积的78.36%,次为Ⅱ类土壤、分布面积占总面积的15.92%,Ⅲ类和劣Ⅲ类土壤仅占总面积的5.72%,显示土壤环境质量良好,但仍须采取有效措施遏制镉污染的迅猛发展。

- 描述：Seasonal water-level fluctuations(WLF) play a dominate role in lacustrine ecosystems. River-lake interaction is a direct factor in changes of seasonal lake WLF, especially for those lakes naturally connected to upstream and downstream rivers. During the past decade, the modification of WLF in the Poyang Lake(the largest freshwater lake in China) has caused intensified flood and irrigation crises, reduced water availability, compromised water quality and extensive degradation of the lake ecosystem. There has been a conjecture as to whether the modification was caused by its interactions with Yangtze River. In this study, we investigated the variations of seasonal WLF in China’s Poyang Lake by comparing the water levels during the four distinct seasons(the dry season, the rising season, the flood season, and the retreating season) before and after 2003 when the Three Gorge Dam operated. The Water Surface Slope(WSS) was used as a representative parameter to measure the changes in river-lake interaction and its impacts on seasonal WLF. The results showed that the magnitude of seasonal WLF has changed considerably since 2003; the seasonal WLF of the Poyang Lake have been significantly altered by the fact that the water levels both rise and retreat earlier in the season and lowered water levels in general. The fluctuations of river-lake interactions, in particular the changes during the retreating season, are mainly responsible for these variations in magnitude of seasonal WLF. This study demonstrates that WSS is a representative parameter to denote river-lake interactions, and the results indicate that more emphasis should be placed on the decrease of the Poyang Lake caused by the lowered water levels of the Yangtze River, especially in the retreating season.
