- 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.

- 基于AHP和GIS的现代文化产业科技发展水平评价及区域品牌建设研究——以鄱阳湖生态经济区为例
- 作者： 许其高 廖智华 来源：电子测试 年份：2015 文献类型 ：期刊 关键词： 现代文化产业 GIS技术 AHP(层次分析法) 区域品牌 产业集群 鄱阳湖生态经济区
- 描述：文化产业区域品牌形成的前提是文化产业集群的基本成熟,要达到这一点,必须进行自主创新,尤其是科技创新。本文首先介绍鄱阳湖生态经济区现代文化产业集群的发展现状,随后利用AHP(层次分析法)测度区内9个城市的现代文化产业科技发展水平,并使用GIS技术作出该区现代文化产业科技发展水平分形图。最后在上述基础上,从区域品牌建设的角度提出现代文化产业集群的发展对策,并提炼出以创建区域品牌为目标的现代文化产业集群发展的几个战略重点。
