From Qu Yuan’s questions to the sky to today’s Digital Earth — a call to understand, connect and protect our shared planet.从屈原《天问》到今日数字地球——以技术理解世界，以合作守护共同的地球家园。
The round skies ninefold stay,
Who contrives them that way?
What feat of might so vast,
Who first works in the past?
How does th’ pivot-cord tied,
Where’s heaven's axis bide?
What eight pillars stand right,
Why the southeast sinks height?
Among the ninefold sphere,
Where lodge, to what adhere?
There nooks and bends they hold,
Who knows their number told?
圜则九重，孰营度之？
惟兹何功，孰初作之？
斡维焉系，天极焉加？
八柱何当，东南何亏？
九天之际，安放安属？
隅隈多有，谁知其数？
2,300 years ago, the great Chu poet Qu Yuan stood on a riverbank and, in The Heavenly Questions, asked how the heavens were structured and ordered. Today, Digital Earth is answering with aerospace information technology.
Grounded in Earth system science, Digital Earth integrates big data, artificial intelligence, cloud computing and geospatial information technologies. Through Earth observation and spatiotemporal information, it provides new ways to understand the planet and support decisions for sustainable development. The ancient question “Who contrives them that way?” now echoes in the everyday work of Digital Earth across industries.
Emerging from the ancient land of Chu and shaped by more than two thousand years of history, Wuhan now stands vibrant on the banks of the Yangtze River. To bring together government, industry, academia, research institutions and application users from China and abroad, and to explore how Digital Earth can advance sustainable development, the 2027 Digital Earth Empowering Sustainable Development Forum and Expo is planned for September 17–19, 2027 at Wuhan International Expo Center. We warmly invite you to join us.
两千三百年前，楚国伟大诗人屈原立于江畔，在《天问》中叩问苍穹的结构与秩序；今天，数字地球正以空天信息技术作答。
数字地球以地球系统科学为基础，深度融合大数据、人工智能、云计算与空间信息技术，开展对地观测、汇集时空信息，为可持续发展提供新的认知框架与决策支撑。当年的“孰营度之”，已成为今日数字地球服务千行百业的日常。
自楚国故地走来，历经两千三百年风雨，武汉正以蓬勃生机立于长江之滨。为汇聚国内外政产学研用各方力量，共谋数字地球赋能可持续发展之道，2027数字地球赋能可持续发展论坛暨博览会拟定于2027年9月17日至19日在武汉国际博览中心举行。我们诚挚邀请您拨冗莅临，共襄盛会。

On the banks of the Yangtze and the shores of East Lake, Wuhan looks forward to welcoming you.长江之畔，东湖之滨。江城武汉期待与您相聚。
In the vast universe, our blue planet orbits the Sun. On Earth, life flourishes in all its diversity. “We must live, and ensure that future generations can too!”
Digital Earth is more than a technical concept. It integrates geographic information systems, spatiotemporal big-data visualization, virtual reality, cloud computing, artificial intelligence and other advanced technologies into a platform for comprehensively observing and understanding the planet. It also carries a cultural commitment to love and protect the Earth for future generations.
Wuhan lies in China’s heartland, where the Yangtze meets the Han River. Known as the “River City” and a historic crossroads, it combines a strong heritage in surveying and remote sensing with a growing digital and aerospace economy. Digital Earth connects the world just as Wuhan connects regions.
In line with the Sustainable Development Goals of the United Nations 2030 Agenda, we call for action across the following seven areas:
浩瀚宇宙中，蓝色星球绕日运行；地球之上，绚丽缤纷的生命绽放、繁衍。——“我们活，也让子孙活！”
数字地球，既是融合地理信息系统、时空大数据可视化、虚拟现实、云计算与人工智能等技术所构建的“全面感知和理解地球”的平台，也蕴含着人类热爱地球、守护地球、惠及子孙后代的庄严承诺。
武汉位于中国腹地中心，长江与汉江在此交汇。作为“江城”和历史上的“九省通衢”，武汉兼具测绘遥感领域的深厚积淀与不断发展的数字经济、航天产业基础。九省通衢通天下，数字地球连世界。
结合联合国《2030年可持续发展议程》的可持续发展目标（SDGs），我们倡议围绕以下七个方向共同行动：
Build agricultural digital twins covering mountains, rivers, forests, farmland, lakes and grasslands; support precision irrigation, fertilization, pest and disease warning and climate-risk management; strengthen food traceability, price-risk monitoring, technology transfer and capacity building so Digital Earth can serve farms at every scale.构建覆盖“山水林田湖草”的农业数字孪生体系，推动精准灌溉、精准施肥、病虫害智能预警与气候风险防控；加强粮食全链条质量追溯、价格风险监测、技术转移与能力建设，让数字地球服务不同规模的农业生产。
Develop basin-scale digital twins integrating satellite, aerial, ground and underwater observations; strengthen real-time monitoring and risk assessment for water changes, pollution, floods, droughts and glacier retreat; use visualization to support precise water management and public awareness.共建流域数字孪生体系，整合卫星遥感、航空摄影、地面传感与水下监测；强化水体变化、水质污染、洪涝干旱、冰川退缩等动态监测与风险评估；以可视化平台支撑精细化用水管理与公众节水意识。

We will promote wider application of Digital Earth technologies, remote-sensing data sharing, technology transfer and talent development, bringing Wuhan’s experience and solutions into global cooperation.
今天，我们汇聚于长江之畔、东湖之滨——武汉。这座城市依托长江经济带核心区位，以及测绘遥感与数字经济领域的深厚积淀，为这场对话提供了天然场景。我们将推进数字地球技术的广泛应用，推动遥感数据共享、技术转移与人才培养，让武汉经验与武汉方案进入更广泛的国际合作。
