调查区位于E75°18′～ 75°32′,N40°22′～40°32′之间,面积约270平方公里。灰旱獭Marmota baibacina为调查区内啮齿动物的优势种群,谢氏山蚤Oropsylla silantiewi为灰旱獭主要寄生蚤。用细菌学方法从3只自毙灰旱獭脏器中检出3株鼠疫菌,确定吐尔尕持地区为一块新的鼠疫自然疫源地。
The survey area is located between E75 ° 18 ’~ 75 ° 32’ and N40 ° 22 ’~ 40 ° 32’ with an area of about 270 km2. Marmota baibacina was the dominant species of rodents in the survey area.
