赛加羚羊是一种神奇的野生动物,现存2个亚种。其中俄罗斯亚种在第一次世界大战结束时仅剩1000只,至二战结束时恢复到9万只,到20世纪60年代上升到130万只以上,但目前又下降到10万只左右。在我国已经灭绝的可能是赛加羚羊蒙古亚种,该亚种在蒙古国的现存野生种群估计只有数百头。导致赛加羚羊野生种群大幅变动的原因很多,首当其冲的应该是赛加羚羊对气候变化的适应性较差。该物种的栖息地通常人烟稀少,气候寒冷,植被覆盖率较差,一旦遭遇持
The saiga is a magical wildlife with two subspecies existing. Among them, the Russian subspecies had only 1000 left by the end of World War I, up to 90,000 at the end of World War II and above 1.3 million in the 1960s, but now it has dropped to about 100,000. The extinct in our country may be the saiga Mongolian subspecies, which is estimated to have only hundreds of existing wild populations in Mongolia. There are many reasons that lead to wild changes in saiga wild populations, and above all bear the brunt of saiga adaptability to climate change. The species habitat is usually sparsely populated, cold climate, poor vegetation coverage, once encountered
