摘要
目的分析钉螺新发现、复现规律,为制订有效的螺情控制策略提供依据。方法采取查阅历史资料及现场调查的方法 ,收集、整理分析2006～2009年安庆市的新增钉螺资料。结果 2006～2009年全市新增钉螺面积14 340 117m^2,新发现钉螺环境150个,复现钉螺环境数117个,两者钉螺面积比值为2.21:1。钉螺新发现和复现均以内陆、湖滩较为严重,主要原因是邻近有螺区钉螺扩散引起。钉螺复现环境数的74.4%(87/117)可归因于邻近有螺区钉螺扩散。钉螺复现距钉螺消灭年份最短的1年,最长的是35年,平均是10年。结论螺情受自然、社会经济诸多因素影响,易出现反复,血防工作应加强螺情监测与灭螺效果巩固。
Objective To under the current status of the newly discovered and recurred snails in Anqing City, and analyze its causes so as to provide scientific evidences for effective snail control strategies. Methods The data of snail situation of Anqing City from 2006 to 2009 was collected by field survey and retrospective investigation,and then analyzed. Results In the period of 2006 to 2009, the newly area of snail was 14340117 m2; the number of environmental units with the newly discovered snails and recurred snails amounted to 150,117, respectively, and their ratio of area was 2.21：1. The newly discovered and recurred tendency of snail situation were most sei＇ious in the inland and lake beach. Snail spreading from the adjacent areas was main reason for snail increasing, for which 74.4% （87/117） of environmental units with the recurred snails ascribed. An average recurring time after snail being eliminated was 10 years, and the shortest time was 1 year, the longest was 35 years. Conclusion As being affected by natural, socio-economic factors, snail situation prone to recurrence, and snail monitoring should be strengthened for schistosomiasis control.
