Chinese scientists complete comprehensive geological map of the moon_我的网站
一 | 中新网北京8月24日电(记者 李京泽 李晓喻)中国外交部发言人林剑24日主持例行记者会。 有记者提问：近日，美方个别官员在社媒攻击中方科技企业，妄称有关中企的高风险技术将造成间谍活动、网络攻击和网络中断风险，并敦促美国在西半球伙伴国迅速转向可信赖的供应商，以保护其公民和国家主权。
Using the latest data from the Chang'e lunar exploration program and other lunar exploration efforts, Chinese scientists have completed a 1:5,000,000 geological map of the entire moon, for the first time providing a more detailed global classification of the moon's late-stage geological layers and key scientific support for China's future lunar research station, landing site selection and deep-space exploration, while contributing to humanity's exploration on the Solar System's evolution, the Xinhua News Agency reported on Thursday.
Measuring approximately 280 centimeters in length and 120 centimeters in height, the lunar geological map includes detailed maps of the moon's polar regions, precisely identifying over 13,000 impact craters and 81 basins, while classifying 14 geological structure types and 17 rock types.
According to the map's compiling team from the Institute of Geology, Chinese Academy of Geological Sciences, the map has achieved systematic innovations in three key areas, based on the latest exploration data from the Chang'e lunar exploration program and other missions, and balancing scientific accuracy and accessibility.
The map updates the moon's geological timescale, revising the starting ages of key periods. The starting ages of the Aitkenian Period and the Nectarian Period have been adjusted to 4.33 billion years and 4.17 billion years, respectively, while the starting age of the Imbrian Period has been slightly revised to 3.92 billion years. This map for the first time provides a more detailed global classification of the moon's late-stage geological layers.
The map also updates the moon's material inventory with high-resolution mineral distribution data and improved rock classifications. Findings from the Chang'e-4 and Chang'e-6 missions led to the identification of gabbronorite in the South Pole-Aitken (SPA) Basin, offering new insights into the moon's deep interior.
The map introduces a customized visualization system for its 1:5,000,000 scale. To meet the requirements of the 1:5,000,000-scale mapping, researchers established differentiated minimum representation scales for various geological features. This ensures that the large-scale map maintains overall readability while preserving key geological characteristics of major scientific significance.
According to Yang Zhiming, director of Institute of Geology, the newly released lunar geological map will support China's future lunar research station, landing site selection, and deep-space exploration, while contributing new Chinese insights into the study of Solar System evolution.

。中方对此有何评论？ 林剑：有关言论捏造事实、颠倒黑白，是赤裸裸的科技霸凌与单边胁迫，中方对此坚决反对。 中国科技企业技术先进、性价比高、服务安全高效，在海外开展业务期间，严格遵守各国法律法规和行业规范，受到当地合作伙伴和民众高度认可和青睐，也为当地经济社会发展和就业作出积极贡献，是名副其实、可信赖的供应商。倒是美方长期在拉美和加勒比搞监听监控、网络攻击，让美洲国家感到不安全、不可信赖。 我们奉劝美方停止政治操弄，停止干涉主权国家自主选择合作伙伴的权利，多做有利于拉美和加勒比地区繁荣稳定的实事。(完） 【编辑:胡寒笑】。
