中亚北鲵的生存状况、濒危程度与保护研究

中亚北鲵（Rannodon sibiricus kessler）又名新疆北鲵,分布于中亚中哈（哈萨克斯坦）边境阿拉套山为中心的两国边境地区,已列入世界红皮书濒危物种,新疆一级保护动物.我国学者在1989年发现于新疆温泉县,经多次调查及估算最高时达到8 000尾.作者在2004年7月考察,发现数量已极少,4处泉水地估算仅有800尾左右（不包括当年还未出卵囊的幼鲵）,种群数量已急剧下降,急需加强保护.可采取扩建保护区、保护生存环境、禁捕、人工繁育和移殖的方法扩大种群数量和分布区.

Research on Ranodon Sibiricus Kessler Living Conditions and Imminent Danger Degree and Protection

Ranodon sibiricus kessler,is distribute at border area taking Alato Mountains as centre on border of China and Kzakhstan,has listed in imminent danger species of World Red Data Book and Xinjiang's Class A protective animal.In 1989 scholar of our country found it in Wenquan County Xinjiang,estimate the most reach 8 000 through investigation for many times.Investigation in July 2004,the writers found less number,estimate only about 800 on four spring water hand in all(do not include small salamnder in ovicyst),population quantity extremely drop,and need strengthening protection badly.To adopt extend protective area,protecting living environment,forbiding catching,artificial propagation and trans-breeding method to enlarge population quantity and distribution area.
