目的研究四川省山丘地区依托系统化生态体系建设阻断血吸虫病传播的效果,为探索血吸虫病防治策略的调整提供依据。方法选择四川省眉山市东坡区山丘型血吸虫病历史重流行区盘鳌乡作为示范区,实施以系统化生态体系建设和血吸虫病防治工作相结合的综合治理措施,并对示范区项目实施后的居民经济收入、血防效果指标等进行比较和分析。结果综合示范区项目于2009年起实施,共投入生态园区建设经费31 735.10万元,建成了优质蜜柚和藤椒等果木为主的经济林种植基地1 866.68 hm2(占园区总耕地面积的72.66%),以及土地生态保护主题园区585.35 hm2,综合整治了历史钉螺分布环境面积的97.04%。到2015年示范区农民人均纯年收入增加4 938元,平均年增长率为14.69%。示范区淘汰了全部耕牛,实现了机械化耕作。居民改水受益率上升52.84%,无害化厕所覆盖率上升18.30%。人群血清学检测血吸虫阳性率从7.69%降至3.50%,病原学检测阳性率从1.18%降至0。查出有螺面积从23.33 hm2降为0。人群血防知识知晓率和行为正确率分别从85.50%、82.60%提高至95.70%、93.90%。结论依托系统化生态体系建设的血吸虫病综合防治策略,符合当前山丘型流行区防治工作的实际,可发挥较好的生态、经济和血防综合效益和效果,为山丘型流行区推进血防工作进程、巩固防治成果、最终实现阻断和消除血吸虫病目标提供了有效的防治新模式。 Objective To study the effect of blocking the transmission of schistosomiasis in the hillsides of Sichuan Province based on the systematic ecological system and to provide basis for exploring the strategy of schistosomiasis control. Methods Pan-Ao Township, a historical endemic area of ​​schistosomiasis mongholicus in Dongpo District, Meishan City, Sichuan Province, was selected as a demonstration area to implement a comprehensive management approach combining the construction of a systematic ecological system and prevention and control of schistosomiasis. The project implementation After the residents of economic income, blood defensive effect indicators such as comparison and analysis. Results The comprehensive demonstration zone project was put into effect in 2009 with a total investment of 31.735 million yuan for the construction of eco-parks. The economic forest planting base mainly consisting of high-quality pomelo and vine peppers was established with 1 866.68 hm2 (accounting for 72.66% of the total cultivated land in the park) ), And 585.35 hm2 of the park for the theme of land ecological protection, which comprehensively rehabilitated 97.04% of the total environmental area for snails. By 2015, the per-capita annual net income of farmers in the demonstration area will increase by 4 938 yuan, with an average annual growth rate of 14.69%. The demonstration area eliminated all cattle and realized mechanized farming. Residents benefit from water improvement rate increased 52.84%, harmless toilet coverage increased 18.30%. The positive rate of serological detection of schistosomes in population decreased from 7.69% to 3.50%, and the positive rate of etiological detection decreased from 1.18% to 0. The snail area was reduced from 23.33 hm2 to 0. The rate of knowledge on the awareness of blood-borne diseases and the correct rate of behavior increased from 85.50% and 82.60% to 95.70% and 93.90% respectively. Conclusion The comprehensive prevention and control strategy of schistosomiasis based on the systematic ecological system accords with the actual prevention and treatment work of current hill-type endemic areas, and can exert better comprehensive benefits and effects of ecology, economy and blood-erosion prevention. Process, consolidate the prevention and treatment results, and finally achieve the goal of blocking and eliminating schistosomiasis provide an effective new prevention and treatment model.
