文档介绍：摘要建国初期血吸虫病流行给江西人民造成了严重的危害,党和政府积极组织群众开展血防工作,建立了一套以政府为主导,各阶层群众密切配合的严密的血吸虫病防控体系。在当时的社会环境下,湖区人民主要采取“治疗病人、病畜,消灭传染源”,“围湖造田、变水田为旱地,改变钉螺孳生环境”、“开新填旧、铲除、火烧杂草,消灭钉螺”和“药物灭螺、管粪管水,避免群众接触有螺水体”等四项改变湖区生态环境的措施,积极开展血吸虫病防治工作。 1950——1984年江西血防工作具有明显的“环境改造”的特点,它以消灭钉螺为中心,主要是通过改变钉螺的生存环境以阻断血吸虫病的传播。“环改血防”对鄱阳湖区域生态环境变迁产生了深刻的影响。一方面它对血吸虫病流行确实产生了一定的防控效果,疫区的感染率降低,疫情压缩,有利于湖区的经济发展和人民的身心健康,优化了疫区生态环境。另?方面它也付出了沉重的环境代价, 导致了湖区水情恶化、洪涝不断、水域污染、生物多样性减少等生态环境问题。关键词:1950——1984;“环改血防”;鄱阳湖区;自然生态变化 Abstract At the beginning ofPRC was prevalence ofschistosomiasis caused serious hann to the people of Jiangxi Province,munist Party and the anized themasses actively tocarry out the work ofschistosomiasl8 astrictschistosomiasis prevention and control system which lS ,the strata of themasses closely cooperation the social enviro姗ent atthattime,people oflake area mainly adopt 4methods tochange the 1ake ecological environment and actively carry out schistosomiasis preventlOn and contr01 work,which are”take thetreatment ofpatients,sick animals and eliminate the source ofinfection”,”reclaim theland,change ofpaddy fields todry land,changing thesnailha_bitatserⅣiroluIlent”,”Open upnew,fill old,eradication and fireweed,and eliminating ofsnails”and”using ofdrugs toeliminate snails,takemanagement of manure andwater toavoid themasses in contact with the water ofsnail”.
