B | Citing concerns about the effects of climate change, the International Olympic Committee said Friday it wants to pick two Winter Olympic host cities in July — putting Salt Lake City quickly into play for the 2034 edition.IOC president Thomas Bach said the Olympic body aims to confirm hosts for both the 2030 and 2034 Winter Games at its meeting on the eve of next year's Paris Olympics.Sweden, Switzerland and France have been working on possible bids for the 2030 edition and Salt Lake City officials have long targeted 2034. That would avoid the United States hosting back-to-back Olympics after the 2028 Los Angeles Summer Games.Picking Salt Lake City a decade in advance would give the IOC a trusted partner amid changing weather patterns and also could keep together people who have worked toward bringing the Olympics back the city that hosted the 2002 Games.The double award proposal by the IOC executive board still needs approval by the full membership at the Olympic body's annual meeting, which opens Sunday in Mumbai, India. That should be a formality.The IOC has declining options for Winter Games hosts. Bach noted that only 15 countries on three continents currently meet the criteria of having at least 80% of existing venues for snow sports and a “climate-reliable” outlook to host events in future decades.“We need to address very quickly this dramatic impact of climate change on winter sport,” Bach said in Mumbai. “By 2040, there remain practically just 10 NOCs who could host these snow events.”A likely longer-term project for the IOC is deciding on a rotation policy of a small pool of regular Winter Games hosts.The next deadline for the 2030 and 2034 Olympics will come Nov. 28-Dec. 1 at a board meeting in Paris. A single preferred candidate for each is expected to be chosen and then would enter into exclusive negotiations with the IOC.That is the new process for selecting Olympic host cities and regions, avoiding the once-traditional campaigns and votes which were at risk of vote-buying schemes.The Japanese city of Sapporo, which hosted the 1972 Winter Games, was once favored for the 2030 edition. That bid was officially dropped this week in fallout from criminal investigations and convictions for corruption tied to the Tokyo Olympics in 2021.___AP coverage of the Paris Olympics: https://apnews.com/hub/2024-paris-olympic-games。经核查,系上游禁牧围栏遭人为破坏所致,已向景区派出所报案,案件正在调查。 视频截图 经地质专家现场评估:牦牛扰动造成局部水体短时浑浊,为短期可逆影响,水体藻类预计一周内恢复;钙华本体结构扰动轻微,轻微创面可通过自然沉积数月内完成修复。

C | 此次事件暴露出管护工作存在短板,我们诚恳向公众致歉。

D | 下一步将全面排查防护设施,强化巡护值守,完善应急处置预案,严防同类事件重演。 据《人民日报》报道,黄龙于1992年列入《世界自然遗产名录》,以“彩池、雪山、峡谷、森林、滩流、古寺、民俗”七绝著称于世。联合国教科文组织评价其“具有绝妙的自然现象或罕见自然美的地区”,被认定为全球三大钙华梯田景观典范之一。 饱含碳酸钙的岩溶水在流动中二氧化碳逸出、碳酸钙沉积形成的层叠状石灰华景观,就是钙华。 “黄龙钙华纯度可以达到99%以上,是极高纯度的一种钙,”四川省地质环境调查研究中心高级工程师刘馨泽解释说,“钙华形成的条件比较严苛,需要很特别的‘源水’。

E | 黄龙处于青藏高原东缘,水体受高山冰雪融水补给,纯度高,颜色才好,结构才精巧。” 然而,除了地表水减少,钙华沙化黑化等问题客观存在,保护还面临着一些困难。在2020年,央视新闻就报道过一则“多名游客踩踏黄龙景区钙华,破坏无法修复”的新闻。

F | 在采访中,四川省地矿局一〇八地质队副队长李德华介绍,钙华形成速度较慢且十分脆弱,形成速度每一年最多的也就是几个毫米。

G | 不仅如此,首先,游客下去踩钙华滩,会造成一种很不好的社会影响,别的游客看到这些游客下去,可能竞相效仿。 第二,下去之后,原有的平衡打破了,把钙华破坏掉,根据人的轻重,破坏的程度可能不一样,但是,绝对改变了原生的层结结构关系。

H | 在九寨沟范围内,山水是融为一体的,人下去之后,人体所带的一些物质,可能也会对水质、环境有一定影响。 最重要的是,钙华滩在岁月沉淀下形成,无论是“牦牛踩踏”还是“人为踩踏”,问题的重点都不是通过比较“谁会带来更大的影响”,来判断谁更“有资格”进入钙华滩。两者的本质都是对脆弱地貌的破坏,如何杜绝这样的破坏才是问题的关键。返回,查看更多。
