彭山县农业技术的提高对血吸虫病防治效果的影响

目的分析农业技术的提高对血吸虫病防治效果的影响。方法通过50年来彭山县血防综合治理中的资料整理,分析评估硝水田的减少、产业结构调整、退耕还林、农业新技术的应用与推广、免耕技术的推广和机耕的广泛使用、耕牛的处置等农耕技术的改变,对血吸虫病防治效果的影响。结果血吸虫病防治初期的1964年,血吸虫感染率达23.00%,晚期血吸虫病患者629例;1972年平坝地区放干硝水田后,同时开展了大规模的群众灭螺,血吸虫感染率下降为5.37%,而同期未放干硝水田的乡血吸虫感染率为13.43%;1984年平坝、丘陵地区大力发展农业基本建设,实施水改旱、水系改造,血吸虫感染率下降为1.52%;长丘山区先后实施了植树造林及退耕还林,到2001年血吸虫感染率下降为0.76%。结论农业技术提高对血吸虫病防治效果明显,但血吸虫病流行地域广,环境情况十分复杂,任何一项措施都不能彻底控制。
