Abstract: Objective To evaluate the schistosomiasis control effect of sequential farmland consolidation and replacing bo? vine with machine. Methods Two farmlands of Qianjiang City were selected as experimental districts，and the sequential imple? menting farmland consolidation and replacing bovine with machine were carried out. The schistosomiasis epidemic situation was ob? served continuously. Results From 2008 to 2012，the human schistosome infection rate decreased by 78.90%，in which the sero? positive rate decreased by 47.88% （χ2 = 368.58，P < 0.01）and the stool positive rate decreased by 55.88%（χ2 =29.92，P < 0.01） . The schistosome infection rate of cattle was 2.54% in 2008，but from 2009，there were no cattle in the area. The Oncomela? nia snail area decreased by 54.78%，and the rate of frames with living snails and the mean density of living snails decreased by 76.49% and 72.63%（χ2 = 11.34， 12.86， P < 0.01）respectively. Since 2009，no infected snails were found. Conclusion The se? quential implementing farmland consolidation and replacing cattle with machine can effectively control the transmission of schisto? somiasis.

摘要： 目的 目的 探索序贯实施 “土地整理和以机代牛” 措施控制血吸虫病的效果。方法 方法 选择潜江市熊口农场和运粮湖 农场为试区， 序贯实施土地整理和以机代牛措施， 观察血吸虫病疫情变化。结果 结果 2012年人群血吸虫感染率比2008年下 降了78.90%， 其中血检阳性率下降47.88% （χ2 =368.58， P＜0.01）， 粪检阳性率下降了55.88% （χ2 =29.92， P＜0.01）； 2008年 耕牛感染率为2.54%， 此后成为无牛区。有螺面积下降54.78%； 活螺框出现率下降76.49% （χ2 =11.34， P＜0.01）； 活螺平均 密度下降72.63% （χ2 =12.86， P＜0.01）； 2009年起， 未查到感染性钉螺。结论 结论 序贯实施土地整理和以机代牛措施， 可有效 控制血吸虫病传播。
