(Xinhua/Bolortsetseg)The "China Corner" themed exhibition made its debut in the Blue Zone of the 17th Session of the Conference of the Parties (COP17) to the United Nations Convention to Combat Desertification (UNCCD) in Ulan Bator, capital of Mongolia, on Monday, showcasing China's experience and achievements in combating desertification. Held under the overall theme of COP17, "Restoring Land, Restoring Hope," the exhibition presents China's efforts and achievements in combating desertification through five chapters across three dimensions. Chapter 1: The Great Green Wall - Strengthening the Ecological Security Barrier in the North Since 1978, China has launched a series of major ecological projects, including the Three-North Shelterbelt Forest Program (TSFP), widely recognized as the world's largest afforestation program. The TSFP was launched in 1978 and is scheduled to run until 2050. It is being implemented in eight phases, with the program currently in its sixth phase. Since the implementation of the TSFP began, forest and grassland coverage in the project area has reached 40.76 percent, while the treatment rate of desertified land has reached 67.82 percent. Chapter 2: Prairie Conservation and Restoration - Bringing Grasslands Back to Life Since the 14th Five-Year Plan period, China has rehabilitated and restored nearly 15.33 million hectares of degraded grassland. In addition, nearly 80.66 million hectares of grassland have been restored through measures such as grazing bans and enclosure, benefiting approximately 12 million farmers and herders. Chapter 3: International Cooperation - Building a Green Community with a Shared Future Upholding the concept of a community of life on Earth, China has established desertification cooperation platforms with Arab countries, Mongolia, and Central Asian countries. It has also supported Belt and Road countries in their efforts to combat desertification, sharing Chinese experience and solutions for global ecological governance. Chapter 4: Scientific Prevention and Control - Combining Knowledge and Technology to Enhance Governance Efficiency China adheres to an integrated approach to the protection and systematic management of mountains, rivers, forests, farmlands, lakes, grasslands, and deserts. It adapts measures to local conditions, prioritizes water-efficient approaches to ecological restoration, and implements targeted treatments in different areas. In terms of technological advancement, the utilization rate of high-quality seeds has exceeded 75 percent, while the mechanization rate of sand control has reached 50 percent. The application of new equipment has increased the efficiency of sand-control operations by more than threefold. Chapter 5: Coordinated Development of Ecological Industries - Achieving Green Prosperity Together China has developed ecological industries and ecotourism initiatives tailored to local conditions, promoting the integrated development of ecological protection, industrial growth, and improvements in people's livelihoods. These efforts have helped transform desert and sandy areas into "green homes," enabling local communities to increase their incomes and achieve greater prosperity. China has seen a continuous decline in the areas affected by desertification and land salinization, becoming the first country in the world to achieve "zero growth" in land degradation. Approximately 53 percent of manageable salinized land has been effectively treated, making China a global leader in ecological restoration. During COP17, which runs through Aug. 28, the "China Corner" will also host a series of thematic side events to facilitate exchanges on ideas, technologies, and practices for combating desertification.

有最新报告指出,如今大学正面临一场严重的作弊危机:越来越多学生用生成式 AI 作弊,没人盯着的线上考试,直接被绕得干干净净,根本起不到考核作用。相关机构也提醒高校:这种无人监考的考试,在 AI 面前基本不堪一击,学生很容易就能钻空子。像 ChatGPT 这类 AI 工具,输几句话就能写出完整论文,现在学生用得特别普遍,已经给整个大学教育出了个大难题。这份报告来自英国智库“政策交流”,他们直接呼吁英国大学:赶紧叫停没人监考的居家远程考试,AI 作弊的风险已经越来越高了。

五 | 还有不少大学官网直接明说自己有线上考试,但半句不提监考措施。而现在已经有好多研究证实,大学生用 AI 应付作业和考试,早就成了普遍现象。英国高等教育政策研究所今年 3 月的调查显示,94% 的学生都承认,自己完成课程考核的时候用过生成式 AI。牛顿教授在报告里说,如果大学还想在 AI 时代保住办学自主权和存在价值,就得从根上重新设计考核方式。他建议,无人监考的线上考试必须立刻叫停,大学得优先用那些经得住考验、不怕 AI 钻空子的考核方法。老师也得好好培训他写道:“不管是线下还是线上、笔试还是其他形式,考核都得有人当面监督,这才该是常态。”除此之外,他还提了两个方向:一是得好好培训大学老师,让他们懂怎么设计靠谱、有效的考核;二是要给用人单位更详细透明的信息,说明毕业生当年是通过什么考核方式拿的学位。作为自由民主党前党魁,文斯爵士评价这份报告 “质量很高,来得也正是时候”。他在序言里写:“现在太多大学的考核体系,AI 一用就直接绕过去了,这么下去学位越来越不值钱,大学的教育作用也会被慢慢架空。”
图源:豆包AI翻译“更关键的是,那些不肯用 AI 作弊、踏踏实实学习的学生,和愿意走捷径的人比起来,反而吃大亏。认真学习虽然难,但收获是实打实的,现在却因为作弊的人变多,变得没了优势。”“要想让公众还信得过学位的含金量,还认可高等教育的社会价值,高校就得赶紧大刀阔斧地改考核方式。除非远程考试能做到百分百安全,不然就该换回线下考试。”牛津大学奥里尔学院院长门多萨勋爵也支持这份报告,说它点出了 “威胁学位标准公正性的一大新问题”。他写道:“期末考核大量用无人监考的线上考试和居家论文,本质上就是在怂恿学生用 AI 作弊。
