鄱阳湖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.

静念园林好 商歌吾事——陶渊明归田探析
作者: 韦燕宁  来源:南宁师范高等专科学校学报 年份:2004 文献类型 :期刊 关键词: 人生价值  归田  恋情  质性自然  仕宦 
描述:陶渊明的一生中,曾数度为官,而每每又旋即辞官归田。这种复杂而矛盾的经历,为后人颇多揣测争议,但见仁见智,始终都没有对其归田的最根本原因得出较为一致的看法。笔者近日重读陶集,仔细搜检其思绪情感,发觉其对田园有一种与生俱来的深深依恋情结。这种情结包括他对田园生活难以割舍的秉性、对亲情故旧的眷恋以及欲以诗文彰显于世的愿望。笔者以为这些因素才是陶公归田的根本原因。

“隐逸”新概念与亦隐隐的陶渊明
作者: 高原  来源:兰州大学学报(自然科学版) 年份:1997 文献类型 :期刊 关键词: 自足的存在  性分  郭象  陶渊明  隐逸 
描述:东晋玄学主张万物各有性分,只须实现自己的性分,获得自身存在的统一,就是逍遥的、自足的存在。传统的“隐逸”由此逆转为“小隐隐林薮,大隐隐朝市。”与此“隐逸”新概念相关联的是东晋大诗人陶渊明据其性分,在其所主动选择的田园耕读生活中获得了自身存在的统一。
