蓝山县南风坳是东亚—澳大利西亚迁飞通道的关键区段,每年有约350万只候鸟途经此地。该地区因独特地形被称为“千年鸟道”。
中新网永州9月22日电(盘俊杰 段祎 王艺淞)当前正值秋季候鸟南迁关键期。地处湘粤交界、南岭山脉核心候鸟迁徙通道的湖南永州市蓝山县四海坪候鸟保护监测站,于今年9月正式启用智能化雷达监测系统,24小时不间断空域扫描替代传统人工观测模式,为过境候鸟撑起科技“保护伞”,让千年南岭鸟道迈入智慧守护新阶段。
每年9月至次年春季,是候鸟集中迁徙的重要时段。全球共有9条主要候鸟迁飞通道,其中4条途经中国。作为全球最繁忙的候鸟迁徙通道,东亚——澳大利西亚迁飞通道串联22个国家,承载着约210种、超5000万只候鸟的迁徙往来。
湖南是东亚——澳大利西亚迁飞通道的关键区段。依托独特的山地地形与气候条件,永州蓝山县南风坳形成天然候鸟迁徙廊道,每年有百余种、约350万只候鸟途经此处迁徙,是名副其实的“千年鸟道”。
四海坪候鸟保护监测站坐落于蓝山云冰山旅游景区,凭借南岭山脉独特的地理与气候优势,形成南北气流交汇的天然风口,是中部地区候鸟南迁的必经要道。每到秋冬迁徙季,大量野生候鸟在此停歇、觅食、补给,再继续南迁旅程。
长期以来,当地候鸟保护工作主要依靠人工巡护、肉眼观测的传统模式,受恶劣天气、复杂地形、高海拔密林等客观条件限制极大。“阴雨天气无法观测高空迁飞鸟群,深山密林、高海拔区域人力难以抵达,观测存在大量盲区。”四海坪候鸟保护监测站工作人员唐嘉豪表示,以往候鸟迁徙规律研判多依赖工作人员经验,监测精准度、时效性和覆盖面均存在明显短板。
今年9月,智能化雷达监测系统正式投用,彻底补齐传统管护短板。该系统可实现24小时不间断全域空域扫描,自动识别、精准统计过境候鸟的种群类别、飞行高度、集群数量、迁徙速度等核心数据,实时汇总更新,搭建动态化候鸟迁徙数据库;同时,系统联动高清监控、智能巡检模块,全程记录候鸟活动状态、智能分析迁徙趋势,有效填补人工巡护无法覆盖高空空域、深山密林的监测空白,推动候鸟监测从“经验判断”全面转向“数据精准研判”。
监测站内,工作人员实时值守智能监测平台,逐条核对、梳理雷达传回的海量数据,精准记录候鸟迁徙峰值时段、优势种群、迁徙流向、单日过境数量等关键信息,规范整理归档、动态更新数据台账,保障监测数据真实完整、全程可追溯。自系统投用以来,监测站已观测记录鹭鸟、鸻鹬、雁鸭等水鸟及各类林鸟数十种,迁徙高峰期日均监测过境候鸟达数千只。
“如今依托实时动态监测数据,我们可精准掌握候鸟南迁时间节点、迁徙峰值、优势种群、栖息分布和迁徙规律,提前预判迁徙高峰,为精准开展巡护值守、隐患排查、栖息地管护提供科学的数据支撑。”唐嘉豪表示。
The five provinces of Qinghai, Tibet, Sichuan, Yunnan, and Gansu issued the "Action Declaration for the Protection of Wild Cordyceps Sinensis Resources in the Five Provinces and Regions" in Xining, clarifying five red lines, aiming to protect the alpine meadow ecology of the Qinghai-Tibet Plateau and wild Cordyceps sinensis resources, standardize market transactions, and balance ecology and people's livelihood.
Six colorful ibises, a national first-level protected wild animal, were recently observed in a lotus pond wetland in Lianjiang, Zhanjiang, Guangdong, setting a local record for the highest number of single observations. Experts believe that this is due to the continued advancement of local wetland ecological restoration and protection work, which provides a high-quality habitat for rare birds.
Panzhihua City in Sichuan has spent ten years successfully improving the ecological environment of the upper reaches of the Yangtze River through measures such as mine restoration, wetland management, and fishing ban protection. The former tailings pond has been transformed into a sea of flowers scenic spot, the deserted beach has been transformed into a place for internet celebrities to check in, and the water quality has continued to be excellent, realizing the green transformation of a resource-based industrial city.

Tropical depression TD29 continues to intensify and will become a mild typhoon "Shuliki" as soon as tomorrow. The Central Meteorological Administration stated that this Friday and Saturday are key turning points in the path. If the Pacific high pressure becomes stronger, it may approach Taiwan, which will affect Taiwan's weather on Monday and Tuesday next week, and there will still be great uncertainty.

In response to the impact of a total ban on feeding pigs with food waste starting next year, the Environmental Management Agency of the Ministry of Environment led various county and city environmental protection units to visit Hongqiao Environmental Protection Technology Company in Guanyin District, Taoyuan on the 22nd to learn about the rapid conversion of food waste into organic fertilizers and low-carbon production technology, and to seek solutions for the diversified decontamination of food waste in the future.

The overflow of Hualien's Matai'an barrier lake is approaching its first anniversary, and local farmland is still covered by sediment. Changhua Dacun Huashu Bank has joined hands with tribes and various civil organizations to launch the "Ma Tai'an Resilient Agriculture Startup" project. It is expected to plant 2,500 Moringa trees to create a spiritual restoration base to aid post-disaster reconstruction.
