可可西里藏羚羊进入回迁季-新华网 新华社西宁7月25日电（记者王金金）记者从三江源国家公园管理局长江源园区可可西里管理处五道梁保护站获悉，监测显示，此前前往可可西里腹地卓乃湖区域迁徙产仔的藏羚羊正陆续结束产仔，开始携幼仔返回原栖息地。 五道梁保护站附近的监控画面显示，7月25日，大约40只雌性藏羚羊带领3只藏羚羊幼仔陆续通过青藏公路3002公里处、青藏铁路五道梁北大桥，藏羚羊已经开始回迁。 专家分析，近年来，回迁羊群中藏羚羊幼仔数量占藏羚羊群总体数量的四分之一至五分之一。 中国科学院西北高原生物研究所副研究员连新明说：“回迁初期，藏羚羊面临较高的被捕食风险，因此羊群中的幼仔数量会比较少，甚至可能出现没有幼仔的情况。” 根据三江源国家公园管理局长江源园区可可西里管理处统计，藏羚羊回迁数量总体呈逐年上升态势，2019年藏羚羊回迁数量为4860只，比2018年增加338只。 连新明说：“预计今年藏羚羊回迁将在9月初结束，回迁藏羚羊数量仍有望继续增加。” 藏羚羊属国家一级保护动物。 每年5月底，来自青海三江源、西藏羌塘、新疆阿尔金山等地的藏羚羊都要前往位于可可西里腹地的卓乃湖产羔。 我国藏羚羊保护专家、陕西省动物研究所（西北濒危动物研究所）研究员吴晓民说：“藏羚羊回迁是雌性藏羚羊结束产仔后，陆续带着幼仔回到栖息地的过程。起初离开产仔地的回迁群体较为庞大，但随后藏羚羊将根据不同的地理种群、沿不同路径回到它们各自的栖息地。” 为确保藏羚羊群安全回迁，记者了解到，日前三江源国家公园管理局长江源园区可可西里管理处已安排工作人员在主要回迁区域，持续开展视频监测和辖区巡逻。 如发现有藏羚羊群试图穿越公路，巡山队员会在第一时间进行临时交通管制，让羊群安全通过野生动物通道，保证其在回迁途中尽可能少受人类干扰。
Tibetan antelope in Hoh Xil enters the moving-back season - www.xinhuanet.com Xinhua News Agency, Xining, July 25 (Reporter Wang Jinjin) – The reporter learned from Wudaoliang Protection Station, Hoh Xil Management Office, Yangtze River Source Park, Three-River-Source National Park Administration, that monitoring showed that Tibetan antelopes who had migrated to Zhuonaihu Tibetan Antelope Aggregation area, the hinterland of Hoh Xil, were finishing giving birth successively and began to bring their cubs back to their original habitat. According to the monitoring pictures near Wudaoliang Protection Station, on July 25th, about 40 female Tibetan antelopes led three young Tibetan antelopes to pass through the Beida Bridge of Wudaoliang on the Qinghai-Tibet Highway 3002 km in succession, and the Tibetan antelopes have started to move back. According to expert analysis, in recent years, the number of Tibetan antelope cubs in the Tibetan antelopes moving back accounted for one fourth to one fifth of the total number of Tibetan antelopes. Lian Xinming, an associate researcher of the Northwest Plateau Institute of Biology of the Chinese Academy of Sciences, said: "In the early stage of moving-back, Tibetan antelopes face a higher risk of being preyed, so the number of cubs in the Tibetan antelopes will be relatively small, and there may even be no cubs. ” According to the statistics of Hoh Xil Management Office of Yangtze River Source Park of Three-River-Source National Park Administration, the number of Tibetan antelopes moving back has been increasing year by year. In 2019, the number of Tibetan antelopes moving back was 4,860, with an increase of 338 compared with 2018. Lian Xinming said: "it is expected that the moving-back of Tibetan antelopes will end in early September this year, and the number of Tibetan antelopes moving back is still expected to continue to increase. ” Tibetan antelope is a national first-class protected animal. At the end of May every year, Tibetan antelopes from Sanjiangyuan in Qinghai, Qiangtang in Tibet, and Altun Mountain in Xinjiang all go to Zhuonaihu Lake in the hinterland of Hoh Xil to give birth to lambs. Wu Xiaomin, an expert on Tibetan antelope protection in China and a researcher of Shaanxi Institute of Zoology (Northwest Institute of Endangered Zoological Species), said: "the moving-back of Tibetan antelopes is a process in which female Tibetan antelopes return to their habitats successively after giving birth. At first, the moving-back population leaving the breeding area is relatively large, but then the Tibetan antelope will return to their respective habitats along different paths according to different geographical populations. ” In order to ensure the safe moving-back of Tibetan antelopes, the reporter learned that the Hoh Xil Management Office of Yangtze River Source Park of Three-River-Source National Park National Park Administration has arranged staff to continuously carry out video surveillance and patrol in the main moving-back areas. If it is found that Tibetan antelopes try to cross the highway, the mountain patrol team will carry out temporary traffic control at the first time, so that the Tibetan antelopes can safely pass through the wildlife passage, and ensure that they are as little disturbed by human beings as possible during the moving-back.
