L9（3^4）正交设计绵羊裸头科绦虫病分布规律的Fuzzy分析

FUZZY L_9(3~4) ORTHOGONAL DESIGN ON THE EPIDEMIC PATTERNS OF OVINE ANOPLOCEPHALIGAE CESTODES DISEASE INVESTIGATION

本文是利用Fuzzy分析法对1982～1984年作者在新疆奎屯垦区四个团场用L_9(3~4)正交表安排的绵羊裸头科绦虫感染分布调查结果进行分析。结果表明裸头科绦虫对垦区绵羊感染分布影响因素大小为绦虫种类>放牧类型>绵羊类别,并分别以无卵黄腺绦虫、山区放牧、羔羊水平组为最高。

The Fuzzy analysis method was used in this paper to analyze the result of the epidemic patterns of ovine anoplocephalidae cestodes disease investigation on an orthogonal design. The investigations were carried out from 1982 to 1984 in 4 state farms in Kuitun reclamation area, Xinjiang. Comparison of the factors influencing the epidemic patterns of ovine tapeworms disease showed that the species of cestodes was the most important factor, the types of the pasture and of the sheep were the second and the third one, respectively. Among them the affection rate of Avitellina tapeworms on lambs grazed on pastures on mountain area was the highest.
