(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.

。他们发现，在日常生活中，使用社交媒体网站的人表现出与可卡因或海洛因上瘾者相似的行为特征。相关论文已发表在《行为成瘾杂志》上。该研究首先要求71名参与者使用Bergen-Facebook成瘾量表对他们使用Facebook的情况进行评分。然后，受试者继续完成爱荷华游戏任务（IGT），这是一个评估决策能力受损程度的经典研究工具。具体方法是向参与者展示四包卡片和四组卡片。每张卡片都显示了获得或损失的金额。要求参与者在其中进行选择，以最大限度地提高收益。正如研究中解释的那样，“参与者还被告知，有些卡片比其他的好，如果他们想做得好，就应该避免坏卡片，选择好卡片。”研究人员发现，声称自己是Facebook过度用户的参与者在IGT上的表现比他们的同龄人差，他们选择了两张“坏”卡片，提供即时B。

二 | 但最终导致了损失。在IGT的后一部分，当参与者有足够的时间观察卡片并知道哪些卡片预测了最大的风险时，实验中显示的行为差异具有统计学意义。从额叶脑损伤患者到海洛因依赖者，IGT已被广泛应用于各个研究领域，但作为一种检测社交媒体依赖者的手段，它仍然是一种创新的方法。随着结构研究的不断深入，研究者们可以肯定地将现有的学习物质成瘾的方法论框架应用于社交媒体用户。虽然上述研究范围较窄，但很有意思，为后续研究提供了一些方法。研究人员已经意识到，在理想的研究状态下，研究人员可以观察参与者的社交媒体使用情况，并根据他们的行为而不是他们填写的调查对他们的社交媒体使用情况进行排名。
