中文导读 新华社10月18日发自长春、哈尔滨的报道介绍了东北虎豹国家公园的野生动物恢复与智能监测。去年年底，园内红外相机拍到一只野生东北虎带着五只幼崽活动，这是国内首次记录到野生东北虎“五胞胎”。据国家林草局公布的监测数据，公园内野生东北虎由2017年的27只增至72只，野生东北豹由42只增至115只；而20世纪90年代末的调查估计，国内野生东北虎仅剩12至16只。公园地跨吉林、黑龙江，面积约1.41万平方公里，2021年正式设立。如今，数以万计的红外相机、无线基站、无人机和卫星遥感组成监测体系，人工智能可识别30多种野生动物，并依据斑纹初步辨认虎豹个体。东宁林场的 Li Gang 回忆，过去换电池、取存储卡要徒步进山。随着虎豹活动范围扩大，村庄附近的相机还能在猛兽靠近时向巡护队和居民预警。文章最后说明，技术并不取代野外巡护，而是让巡护更有针对性。文中据新华社报道改写，种群数字与历史背景参考《中国日报》报道核对。
正文 Late last year , an infrared camera in northeast China filmed a wild Siberian tiger walking through the forest with five cubs behind her . It was the first record of such a large wild litter in China . According to a Xinhua report on October 18, three of the cubs have since left their mother . The footage is a small sign of a wider recovery in the Northeast China Tiger and Leopard National Park .
本段译文 去年年底，中国东北的一台红外相机拍到一只野生东北虎（西伯利亚虎）在林中行走，身后跟着五只幼崽。这是中国首次记录到野生东北虎一窝产下这么多幼崽。据新华社10月18日报道，其中三只幼崽此后已离开母亲。这段影像是东北虎豹国家公园更大范围恢复的一个小小迹象。
Official monitoring data show that wild Siberian tigers in the park have risen from 27 in 2017 to 72, and wild Amur leopards from 42 to 115. In the late 1990s , surveys estimated that only 12 to 16 wild Siberian tigers remained in China . Hunting limits protected areas and the repair of damaged forests helped prepare the ground . The park , which covers about 14,100 square kilometers in Jilin and Heilongjiang provinces , was formally set up in 2021.
本段译文 官方监测数据显示，公园内的野生东北虎已从2017年的27只增至72只，野生东北豹从42只增至115只。20世纪90年代末，调查估计中国境内只剩下12到16只野生东北虎。限制狩猎、设立保护地以及修复受损森林，为此后的恢复打下了基础。这座公园地跨吉林、黑龙江两省，面积约14100平方公里，于2021年正式设立。
Technology now does much of the watching . Tens of thousands of cameras are spread across the forest , and wireless signals cover more than 80 percent of the park , so footage can reach the park office within about a minute . Drones fly over remote land and look for possible fires or illegal activity . Artificial intelligence can recognize more than 30 kinds of animals and make a first guess about which tiger or leopard appears , because each big cat has its own pattern of marks . Researchers then check other features before they add the animal to its record .
本段译文 如今，大量观察工作由技术来完成。数以万计的相机分布在林区，无线信号覆盖公园80%以上的面积，因此影像大约一分钟内就能传到公园管理部门。无人机飞越偏远地带，查找可能的火情或非法活动。人工智能可以识别30多种动物，并初步判断画面中出现的是哪一只虎或豹，因为每只大型猫科动物都有自己独特的斑纹。研究人员随后会核对其他特征，再把这只动物加入它的档案。
For forest workers , the change is practical . Li Gang , who has worked at a forest farm in Dongning , Heilongjiang , since 2009, remembers walking into the mountains to change batteries and collect memory cards by hand . “On one occasion , I walked 17 kilometers carrying about 200 batteries and spare cameras ,” he told Xinhua .
本段译文 对林区工作人员来说，这种变化实实在在。自2009年起就在黑龙江东宁一处林场工作的Li Gang记得，过去要徒步进山，手动更换电池、取回存储卡。“有一次，我背着大约200块电池和备用相机走了17公里，”他对新华社说。
The recovery also brings a new challenge . In parts of the park , villages and wildlife areas overlap . Cameras near homes can detect tigers , leopards , bears and wild boars when they enter risk zones , and alerts go to patrol teams and local residents . Rangers can also warn people through local chat groups .
本段译文 恢复也带来了新的挑战。在公园部分地区，村庄与野生动物栖息地相互重叠。住宅附近的相机能在虎、豹、熊和野猪进入风险区域时发现它们，并向巡护队和当地居民发出警报。护林员还可以通过当地的聊天群提醒村民。
Not everything depends on machines . Workers have removed more than 290 sections of fence along the China-Russia border to reopen routes for wildlife . Li says the cameras do not replace rangers in the field , but they help patrols go where they are needed and avoid disturbing animals . “We want to give people and wildlife room to live without disturbing one another ,” he said .
本段译文 并非一切都靠机器。工作人员已沿中俄边境拆除了290多段围栏，为野生动物重新打开通道。Li Gang说，相机并不能取代在野外工作的护林员，但能帮助巡护去往真正需要的地方，并避免打扰动物。“我们希望给人和野生动物留出生活空间，彼此互不打扰，”他说。
