- 试论明清时期鄱阳湖地区民间信仰的佛教化趋同
- 作者： 程宇昌 来源：江西社会科学 年份：2015 文献类型 ：期刊 关键词： 佛教 鄱阳湖 明清时期 民间信仰
- 描述：湖区民间信仰的佛教化,这与佛教名山庐山的宗主地位的辐射作用密不可分,与民间佛事活动、观音菩萨的普世价值的影响也不可分割。在这些因素的影响下,民间信仰与佛教交相互融,尤其是民间信仰神灵的佛教化,呈现出佛教化色彩。

- 鄱阳湖非平稳水位波动及其与长江的交互作用关系
- 作者： 戴雪 万荣荣 杨桂山 来源：地理学报(英文版) 年份：2015 文献类型 ：期刊 关键词： Yangtze earlier seasonal intensified downstream lacustrine river representative flood dominate
- 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.

- 长江上游水库调度缓解鄱阳湖枯水情势作用研究
- 作者： 要威 余启辉 游中琼 来源：人民长江 年份：2015 文献类型 ：期刊 关键词： 三峡水库 水库调度 鄱阳湖 提前蓄水 控制性水库 枯水情势
- 描述：近年来,鄱阳湖出现了枯水时间提前、枯水位偏低、持续时间延长等现象,其中水库蓄水是造成鄱阳湖枯水情势恶化的重要原因之一。对通过调整长江上游干支流控制性水库蓄放水过程来缓解鄱阳湖枯水情势可行性进行了研究。分析比较了三峡水库及上游控制性水库提前蓄水或延长蓄水时间等4个方案对缓解鄱阳湖枯水情势的效果。结果表明,调整上游干支流控制性水库调度运用方式,只能在部分时段缓解湖口水位降低的情势,且幅度较为有限,难以根本解决湖区低枯水位的问题。
