  Protecting the Mogao Grottoes has become a daunting task due to a variety of problems, such as changes in the colors of the ancient paint after exposure to light, the efflorescence of the frescos over time, and the variable changes in humidity and heat generated by visitors, all of which can cause damage to the invaluable frescos. Digitalization is an important way to keep the grottoes alive forever.
  The Dunhuang Academy inaugurated "Digital Dunhuang", a digitalization project, in order to create digital versions of the Mogao Grottoes in the 1990s. The project aims to establish complete digital files on the grottoes, including its full collection of cultural relics, by processing and permanently storing 2D and 3D data through the application of photogrammetry and 3D digital reconstruction technologies, among other approaches.
  "By the end of 2021, the project had finished compiling a digital data collection on 268 grotto caves in Dunhuang, image processing for 164 caves, and the 3D reconstruction of 45 painted sculptures, 146 caves and seven ruins, while delivering a panoramic tour program for 162 caves. Our academy also completed the digital scanning of more than 50,000 archived images and established a digital team with over 100 members," said Wu Jian, director of the Dunhuang Academy's Conservation and Research Division.

  提出这样的目标,底气在哪里?
  一是产业发展提速提质,共富根基更加扎实.5月17日,桐庐举行重大项目集中签约推进大会,包括吉利集团在内的10个重大项目,涵盖新能源,新材料,快递物流,医疗器械等多个领域,总投资247.15亿元.桐庐县委书记夏积亮告诉记者,在项目招引过程中,桐庐锁定大企业,科创型企业,加快产业发展模式向智力支撑型,技术支撑型转变,力争打造更有竞争力的产业集群,迈向绿色低碳的共富之路.
  二是美丽建设领先领跑,共富底板更加亮丽.作为浙江省推进共同富裕第一批实践试点,桐庐制定出台美丽乡村,美丽经济两个行动方案,推进实施17个示范村,12条风景线建设,其中2条风景线入选杭州市未来乡村共富引领带建设.今年,桐庐开展新一轮美丽乡村建设,进一步打通"两山"转化通道,把乡土风貌,特色文化与现代旅游需求有机结合.上半年全县村级集体经济总收入为2.14亿元,经营性收入1.38亿元,23个村经营性收入达到100万元.一季度农村居民人均可支配收入为12744元,同比增长6.9%,增幅居杭州市第一位.
  三是文化文明兴盛兴旺,共富内涵更加充实.桐庐今年实现乡村"复兴少年宫"全覆盖,总量达195个,49项充满乡土特色的课程丰富了乡村少年儿童的暑期生活.同时,桐庐推出"忆江南·富春山居游",以富春江为纽带,串起桐君山,严子陵钓台,大奇山国家森林公园等核心景区,让游客真切感受"富春山居图"实景地的独特魅力.
  夏积亮表示,写好文旅融合文章,是桐庐争当共同富裕县域标杆的重要举措,必须加紧探索打造具有富春山居辨识度的文化标识,丰富差异化的公共文化服务供给,建设范仲淹纪念馆,中国诗词文化馆等一批地标性文旅场馆. (经济日报记者 黄 平 柳 文)
