- 浅谈江西鄱阳湖区域的瓷上绘画职教环境
- 作者： 徐光达 支林 来源：戏剧之家 年份：2015 文献类型 ：期刊 关键词： 职业教育 传统 瓷上绘画 反传统 反思性教学
- 描述：“瓷上绘画”又名为瓷版画,是江西省内一门独特的民间绝技,有着自己独特的语言魅力和欣赏价值。但是,随着一代代老艺人的离去,其制作工艺也几近失传。2013年,江西科技师范大学开办了“瓷上绘画班”,成为了江西首例从传统文化中去开发新型职业人才培养模式的尝试,在传承传统文化的同时,又为学生的就业开辟了新的道路、新的方向、新的起点。

- 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.
