On the location conditions for propagating the culture of the Yangtze basin

从自然生态环境角度 ,探讨了长江文化繁衍的区位条件 .分析表明 :长江流域地处世界亚热带的一方宝地 ,是滋养文化的“绿洲”和“沃土”;贯穿中国地形的三大阶梯 ,促成了文化的差异性与不平衡性 ;背靠“世界屋脊”、面向浩翰海洋 ,成为文化交流的屏障与通道 ;位于自然过渡区和生态交错带 。

This paper probes into the location condition for propagating the culture of the Yangtze River from the angle of natural ecological environment. The analysis indicates that, the Yangtze basin is located in a precious terra of subtropics, which is 'oasis' or 'rich soil' for nourishing culture; it backs to 'the roof of the world' and faces to the vast ocean which makes it the protective screen and passageway for culture communication; it is located between the natural interim zone and ecological crisscross belt, which presents the abundance and diversity of the culture.
