In Bai settlement formation and development history, its diverse natural appearances and rich cultural styles have the dual characteristics in natural and cultural heritage. Nuodeng salt-village is a connection between central plains culture and South Asia culture, also a complete ecological museum. By this time, this essay put Jinan springs under the view of mixed heritage based on the background of its history and geography, to identify the natural and cultural value of Nuodeng salt-village by comparison and conclude the heritage protection planning accordingly.展开更多
