新时代中国调研行之文化中华丨良渚遗址：高科技呵护文明圣地光彩

Core Viewpoint - The "Liangzhu Plant Essential Oil," initially effective in controlling moss at the Liangzhu archaeological site, has lost efficacy due to moss developing resistance, prompting researchers to develop a "2.0 version" of the product [1][3]. Group 1: Research and Development - The original essential oil was effective for six months, but its effectiveness has now decreased to four to five months [3]. - Researchers are exploring various methods to protect the Liangzhu site, including the use of natural plant agents and innovative techniques like light-based physical methods to combat moss and mold [5][8]. - The Liangzhu site, characterized by its moist environment, presents unique challenges for preservation, requiring continuous exploration and adaptation of methods [3][7]. Group 2: Interdisciplinary Collaboration - The Liangzhu archaeological site protection involves collaboration across multiple disciplines, including physics, chemistry, hydrology, geology, biology, and big data [8]. - The establishment of the first southern humid environment soil heritage protection laboratory in China, covering 1,500 square meters, aims to provide scientific solutions for the preservation of Liangzhu and other similar sites [8]. - The preservation efforts are supported by various academic institutions, including the Chinese Academy of Cultural Heritage, Dunhuang Research Institute, and several universities, indicating a collaborative approach to heritage conservation [8]. Group 3: Historical Context and Significance - The Liangzhu archaeological site was discovered in 2007, with the water conservancy system found in 2015, and it was designated a UNESCO World Heritage Site in July 2019 [7]. - The preservation work at Liangzhu is closely integrated with archaeological research, especially after the park's opening to the public, highlighting the need to balance visitor experience with site protection [7]. - The site’s climate, characterized by cold winters and hot, humid summers, poses significant risks to the stability of the earth structures, necessitating innovative preservation strategies [7].
