为了掌握不同海拔地域羊肺线虫病流行现状和季节动态，从而防治此病，采用贝尔曼氏幼虫分离法研究了康定县炉城镇折多塘村和康定县姑咱镇时济村羊肺线虫幼虫的发生情况。结果表明：折多塘村5月份肺线虫幼虫感染率为32．39％，是幼虫感染的高峰期，8月份为12．68％，再出现一次小高峰；时济村4月份幼虫感染率44．44％，也是幼虫感染的高峰期，而在6～9月份气温高达30℃以上，空气较为干燥，粪便中幼虫死亡率高，感染率基本为零。
為瞭掌握不同海拔地域羊肺線蟲病流行現狀和季節動態，從而防治此病，採用貝爾曼氏幼蟲分離法研究瞭康定縣爐城鎮摺多塘村和康定縣姑偺鎮時濟村羊肺線蟲幼蟲的髮生情況。結果錶明：摺多塘村5月份肺線蟲幼蟲感染率為32．39％，是幼蟲感染的高峰期，8月份為12．68％，再齣現一次小高峰；時濟村4月份幼蟲感染率44．44％，也是幼蟲感染的高峰期，而在6～9月份氣溫高達30℃以上，空氣較為榦燥，糞便中幼蟲死亡率高，感染率基本為零。

In order to grasp the different regional sheep pulmonary nematode disease prevalence and seasonal dy -namics ,so as to prevent the disease ,the situation of sheep nematode larvae were checked by Behrman's method in Kangding county Lucheng town Zheduotang village and Kangding county Guzan town Shiji village .The re-sults showed that :the infection rate of nematode larvae in May in Zheduotang village was 32 .39% ,which was peak of larva infection ,12 .68% in August ,another small peak .The infection rate of nematode larvae in April in Shiji village was 44 .44% ,which was the peak of larvae infection ,and from June to September ,due to the temperature up to 30 ℃ ,the dry air ,and high larval mortality in feces ,the infection rate was almost zero .
