Abstract:

Objective To evaluate the performance of small Oncomelania snail control projects in Hubei Province in 2009 and 2010，so as to explore the best snail control project in different areas. Methods The expense?effect，expense?efficiency and cost?utility analyses were carried out to analyze the small snail control projects with reference to the relevant schistosomiasis japoni? ca prevention and control index system. Results The coverage rate of snail control was 40.15%，the decrease rate of the snail ar? eas was 32.86%，the unit cost for the snail control was 0.39 Yuan/m2 ，the cost of reducing 1% of the snail area was 67.34 ten thou? sand Yuan，the total benefit was 15 554.14 ten thousand Yuan，the ratio of cost to benefit was 7.03，the net benefit was 13 341.44 ten thousand Yuan，and the ratio of cost to net benefit was 6.03，and the investment ratio was 1∶2.11 in the 183 small snail control projects. Conclusion There is an obvious and respectable short?period effect of the small snail control projects.

摘要：

目的 对湖北省2009年和2010年小型灭螺工程进行绩效评价， 探索不同地区最优效益工程的灭螺措施。方法 参照血吸虫病防治有关指标体系， 对湖北省小型灭螺工程费用?效益、 费用?效果及费用?效用进行评价。结果 183项小型灭螺工程灭螺覆盖率为40.15%， 有螺面积下降率为32.86%。单位面积灭螺费用为0.39元/m2 ， 有螺面积下降1%的费用为67.34万元。总效益为15 554.14万元 ， 总效益费用比为7.03； 净效益为13 341.44万元， 净效益费用比为6.03； 政府与工程单位投资比为1∶2.11。结论 小型灭螺工程短期效果明显， 效益良好。
