广西是中国人工林面积最大的省区,人工林面积约1.5亿亩,约1000万公顷,居中国第一。此次监测站建设旨在提升林业碳计量精准度,支持碳汇交易和生态政策制定。
中新网南宁10月11日电(韦佳秀)广西壮族自治区市场监督管理局10日介绍,日前,广西壮族自治区计量检测研究院联合中国计量科学研究院、广西科学院,依托中国林业科学研究院热带林业实验中心,在凭祥市建成中国首个面向南亚热带人工林的“天—空—塔—地”全要素碳通量综合监测应用场景。
这一突破性成果标志着广西在林业碳计量精准化、立体化、长时序化方向迈出开拓性一步,将为中国“双碳”战略实施、面向东盟生态合作提供关键技术支撑。

具体来说,这个监测站最厉害的“法宝”,是一台精度达到十亿分之一级别的温室气体分析仪,相当于给森林装了个超灵敏的“鼻子”——哪怕空气中每十亿个气体分子里多了一个二氧化碳,仪器都能精准捕捉到。在这个“超级鼻子”24小时不停监测下,森林每分每秒“吸”了多少碳、“呼”了多少氧,温度降水变了之后固碳能力有什么变化,全部能实时记录下来,连土壤里微生物呼吸释放的二氧化碳都能算得清清楚楚,相当于把森林的“新陈代谢”过程全程直播。
广西是中国人工林面积最大的省区,人工林面积约1.5亿亩(约1000万公顷),居中国第一。有了这套精准监测系统,林业碳汇项目交易时,买卖双方有了可核验的数据支撑,农户种的树吸了多少碳、能换多少钱,拿出监测数据就能明明白白结算。
这套监测系统产出的精准数据,用处还不止算碳账:以后想知道怎么种树固碳效率最高、不同树种适合种在什么地方,都能从监测数据里找答案,也能给广西制定碳中和目标、出台生态补贴政策提供最实在的依据。
广西的南亚热带人工林和东盟很多国家的森林类型相近,这套监测方法未来还能推广到东盟国家,为跨境生态保护、全球热带森林碳汇评估提供中国经验,让广西的林业技术也能走出国门,为全球气候变化治理贡献广西力量。(完)

Typhoon No. 28 Little Bear intensified into a severe typhoon on the morning of the 11th. It is currently located 700 kilometers east of Iwo Jima, moving north-northwest and will not affect the East Asian land. Meteorological experts pointed out that tropical disturbances are still active in the low latitudes of the western Pacific, and a new typhoon may be generated later this week, named "Qiangpi". However, the follow-up path is very different. Some models predict that it will go westward and approach Taiwan. It is necessary to continue to observe the configuration of the trough line and the subtropical high.

A large number of poisonous man-of-war jellyfish have recently appeared at Waiao Beach on the north side of Wushi Port in Yilan County. Surfers felt severe pain after accidentally touching it, describing it as being "electrically exploded". Tourists also picked up the jellyfish and buried them. The Ocean Council warned that the tentacles of man-of-war jellyfish contain toxin stinging cells. Human contact will cause severe pain and red whip marks. Even if the toxicity may still be fatal, the public is urged not to touch it.
Wang Longgui, a retired fisherman from Longmatan District, Luzhou City, became a public welfare fisherman after the fishing ban in the Yangtze River. He patrolled a 10-kilometer section of the river for six years and witnessed the return of fish. Through ecological protection, cross-border collaboration and green development measures, Luzhou promotes the restoration of the Yangtze River water ecology and realizes the transformation from "relying on water to draw water" to "protecting water and promoting water".
The Yichang oil depot of PetroChina Hubei Sales Company was located in the core protection zone of the Chinese sturgeon and was completely relocated to the Yaojiagang Chemical Park in Dongshi Town, Zhijiang. It was dismantled and regreened using a sawing method with zero pollution. At the same time, China Three Gorges Corporation announced that my country's first batch of fully artificially bred third-generation Chinese sturgeon fry have survived for more than two months and have an average weight of more than 100 grams. Two-way efforts are being made to help the recovery of the Chinese sturgeon population.
Affected by the cold air, most areas in the north will experience a temperature drop of 4 to 6°C in the next three days, with a local temperature drop of 8 to 12°C, accompanied by winds of magnitude 4 to 5 and gusts of magnitude 6 to 8. Shaanxi, Shanxi, Hebei and other places will experience local heavy rain or heavy rain, and southwest, Jiangnan and other places will usher in a new round of rainfall.

The Central Meteorological Administration predicts that the high temperature today will be about 29 to 31 degrees in the northern and eastern half, 31 to 33 degrees in the central and southern parts, and the highest temperature in the inland areas will be 34 to 35 degrees, and may reach 36 degrees in some places. Sun protection and hydration are also reminded. Outlying islands and air quality are also explained. The weather will be mainly cloudy to sunny in the next few days, with occasional brief showers in the east.
