爲了解我國(guó)布魯氏菌病（以下簡稱煙到“布病”）一類地區羊布病造成(chéng好拿)的直接經(jīng)濟損失及防控投站通入合理性，構建了羊布病直接經(jīng)濟損失指标體系和防控成(chéng高火)本效益評估方法，并對(duì)我國(guó)羊主産區4省份17市縣對國的防疫部門和319個養羊場戶進(月林jìn)行實地走訪與問卷調查。共回收防疫部門問卷21份，場戶有效問卷301份土生，涉及124個布病羊場和177個無布病羊場。運用Excel、路農SPSS等軟件，對(duì)問卷數據進(jìn)行遠器統計分析。結果顯示：2020年單隻布病羊直接經(jīng)濟損說場失平均爲4 557元（不含奶羊），各省份羊布病損失爲 1.8億~20近視.4 億元，其中養羊場戶損失占比較高，占總損失的 7熱國3.0%~81.0%；各省份政府的布病防控效益成通美(chéng)本比爲5:1~3得關8:1。結果表明，羊布病導緻的經(jīng)濟損失嚴重，對(duì)其防控熱商可取得顯著經(jīng)濟效益。建小街議養殖戶及政府進(jìn)一步加大布病防控投入，而且政府應錢鐘提高預防性投入比重。本研究爲優化布病防控政策提供了技術支撐。

In order to identify the 做火direct economic loss caused by shee資船p brucellosis in class I來湖 area of China and長數 the financial rationality in its pre公月vention and control，an index system o從醫f direct economic loss caused by the讀大 disease and a cost-benefit evaluat煙窗ion method of its preventi電草on and control were estab自理lished. A field visit 舞還and questionnaire investigation were 舞了conducted in 319 farms/households下靜 and the disease prevention departme影唱nts in 17 cities/counties in 4 provin能生ces which are the main shee購鐵p production area. 21 qu電人estionnaires from the disease preventio討拿n departments and 301 fr科都om farms/households were collected書訊，covering 124 brucellosis infected farm白樂s and 177 brucello放房sis free farms.
