China unveils refined lunar map, empowering future moon exploration_我的网站

古剑奇谭

一 | A Chinese research team has completed an updated geologic map of the entire moon featuring a scale of 1:5 million, the Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS), said on Thursday. Representing a significant scientific iteration from the 2024 version, this map effectively rewrites the moon's geologic history based on the latest research findings. "The lunar geologic history has indeed been rewritten -- more precisely, refined and systematized," said Yang Zhiming, director of the IGCAGS. Specifically, a primary achievement of this update is the recalibration of the moon's ancient geologic eras. The new map systematically updates the age boundaries of the moon's three ancient geologic periods, namely the Aitkenian, Nectarian and Imbrian periods, drawing on recent advances in international chronology. Crucially, Chang'e-5 samples confirmed volcanic activity on the moon as recently as 2 billion years ago, extending its geologic lifespan by 1 billion years from the previously accepted 3 billion years. This independent dating data has now become a cornerstone of the global lunar geologic timescale. Highlighting these spatial discoveries, the new global lunar geologic map is the first comprehensive canvas to bear exclusive findings from the Chang'e-6 mission. "The lunar samples and this map will provide a new starting point for scientific discussions regarding the lunar far side," said Jin Ming, an associate researcher at the IGCAGS. The map details the age of young mare basalts on the lunar far side obtained from the Chang'e-6 samples, recording the region's volcanic history. Furthermore, it reveals that KREEP rocks, enriched with rare earth elements and other strategic resources, are far more continuous and abundant in the Oceanus Procellarum than previously estimated. This discovery, achieved by eliminating spectral noise, prompts a systemic reevaluation of the moon's early magma ocean crystallization and internal thermal evolution. Beyond its scientific data, the 2.8-by-1.2-meter map introduces a proprietary cartographic standard. Identifying over 13,500 impact craters and 81 basins, it employs a unique color scheme rooted in geologic logic and traditional Chinese aesthetics, following a "lighter for younger, darker for older" principle. Furthermore, this standard will also be applied to future geologic mapping of Mars and asteroids, ending reliance on foreign standard systems. "This goes beyond showcasing technological soft power. This standard will be extended to future planetary geologic mapping, establishing an independent intellectual property framework for China's deep space exploration," Yang said. 。中新网北京8月22日电题：义乌，一座城撑开56个民族的“人生舞台” 　　作者任德辉曾玥张斌董易鑫　　初到义乌，满眼是国际化的街景：招牌上的外语与中文紧密交织，非洲商人在五金档口熟练砍价，中东小伙在餐馆里穿梭忙碌。这座浙江中部的县级市，用两三代人的时间，从阡陌农田崛起为全球小商品之都。　　然而，比市场更动人的，是这里的“空间感”。这座仅1105平方公里的城市容纳了56个民族，让34万余名少数民族群众不仅找到了营生的机会，更找到了安放过往、施展抱负、传承文化的广阔舞台。航拍义乌市场一景。董易鑫摄　　人尽其才：凡是过往皆为序章　　新疆姑娘吐送尼莎肉孜买提(莎莎)的人生履历颇为丰富：学过多种语言，在云南当过警察，回乌鲁木齐做过翻译和老师。

二 | 当她来到义乌，这些看似零散的经历，在五爱社区找到了“接口”。　　五爱社区居住着2240余名各族群众，有来自62个国家的常驻外商。

三 | 作为辅警，莎莎调解纠纷、消除误会。依托社区成立的“阿依乐·莎莎”石榴红工作室，她时常策划中文课、手工班和AI讲座，促进邻里交往，让归属感在潜移默化中生长。

四 | 　　在义乌，个人的“存量”技能从不被浪费。

五 | 通过构建“1+3+3+N”民族工作服务体系，这座城市搭建起“石榴红”家园、共富基地、特色工作室等一批民族工作阵地，为不同背景的人才匹配岗位与角色，让每位建设者都能人尽其才、心有所寄。蒙古族姑娘塔娜介绍生意情况。董易鑫摄　　赋能梦想：从单打独斗到携手共富　　蒙古族姑娘塔娜刚来义乌时，口袋里仅有3000元人民币。　　她进过外贸公司，也自己倒腾过节日用品，生意起步之初，是义乌市民族团结进步促进会接纳了她。在这个圈子里，大家聊的是展位资源，谈的是市场风向，生意与生活上的互帮互助，让她度过了最艰难的起步期。　　如今，塔娜已创立多个外贸品牌，产品远销中亚、中东、北非。从曾经的“探路者”变成如今的“引路人”，她将企业打造成“大学生共富实践基地”，手把手教后辈闯荡国际市场。“我希望把‘义乌温度’带回家乡，带回草原。

六 | ”塔娜眼中的义乌不缺商机，更不缺情义。　　义乌的商业逻辑，不仅在于交易的便捷，还在于生态的包容。在这里，民族同胞从来不是孤立的个体，而是嵌入到全球最大的贸易网络中，共建生态，共享红利。畲族老板钟敏设计的民族风格创意饰品。董易鑫摄　　延展文化：让“小众”走向世界　　在义乌国际商贸城，畲族老板钟敏的饰品店是一处独特的风景。

七 | 热销品中，既有源自畲族“双凤朝阳”图腾的设计，也有取材自“十二花神”、《白蛇传》及穆桂英传说的创意。

八 | 这些融合传统文化与现代表达的作品，让世界各地的客商眼前一亮。　　“以前我们只卖产品，现在更希望在产品中传递我们的文化。

九 | ”钟敏感慨。一款“双凤朝阳”饰品，上市仅两个多月就售出700多套。从摆地摊到站上世界舞台，钟敏把生意越做越大的底气在于：义乌不仅拓宽了销售渠道，更让“小众文化”被世界看见。　　中欧班列拉长了市场的半径，全球数贸中心加速了货品的流转，而义乌这座城，则延展了文化的边界。　　在这里，56个民族的文化自信，随着集装箱一同出海，在世界版图上留下鲜明的中国印记。从就业到乐业，从安居到安心，义乌用一座城的胸怀，撑开了56个民族的人生维度。
