目的：考察云南省高原丘陵血吸虫病流行地区不同农林业系统的防螺效果，为高原丘陵地区农林业血吸虫病防治工程建设提供参考。方法：2010年在云南省洱源县养螺农田建立多种农林复合系统防治螺林试验区，2018年开展经济效益和防治螺效果调查。建立了模糊综合评价模型，筛选综合效益较高的农林复合系统。结果：共建立了14种不同农林业系统的防治螺蛳林试验区。经济效益分析表明，“核桃+大蒜”模式经济效益最佳，年经济效益为27万元/hm2，其次是“核桃+辣椒”模式（年经济效益为12万元/hm2）和“核桃+蔬菜”模式（年经济效益为10.5万元/hm2）。“核桃+辣椒”、“核桃+烟草”、“核桃+大蒜”等8种农林业系统均未检出钉螺；然而，在其他类型的系统中发现了不同密度的蜗牛。模糊综合评价表明，“核桃+大蒜”模式综合防治效果最好，“核桃+辣椒”模式次之，“核桃+烟草”模式次之，纯草地模式对钉螺的防治效果不明显。结论：农林复合系统是高原丘陵血吸虫病流行地区林业血吸虫病防治的优先途径，既能达到防螺效果，又能促进贫困丘陵地区的经济发展和生态建设。
OBJECTIVE: To investigate the efficiency of various agroforestry systems for snail control in plateau hilly schistosomiasis-endemic areas of Yunnan Province, so as to provide insights into the construction of agroforestry schistosomiasis control projects in plateau hilly regions.METHODS: The pilot areas of snail control forests with various agroforestry systems were built in snail-breeding farmlands in Eryuan County, Yunnan Province in 2010, and the economic benefits and snail control effect were investigated in 2018. In addition, a fuzzy comprehensive evaluation model was created to screen the agroforestry system with high comprehensive benefits.RESULTS: A total of 14 types of pilot areas of snail control forests with various agroforestry systems were built. Economic benefit analysis showed that the"walnut + garlic"pattern had the best economic benefit, with annual economic benefits of 270 000 Yuan/hm2, followed by the"walnut + chili"pattern (annual economic benefits of 120 000 Yuan/hm2) and the "walnut + vegetables"pattern (annual economic benefits of 105 000 Yuan/hm2). No snails were detected in 8 types of the agroforestry systems, including the"walnut + chili"pattern, the"walnut + tobacco"pattern and the"walnut + garlic"pattern; however, there were snail found with various densities in other types of systems. Fuzzy comprehensive evaluation showed that the"walnut + garlic"pattern had the best comprehensive control effect, followed by the"walnut + chili"pattern and the"walnut + tobacco" pattern, while the pure grassland pattern showed no effect on snail control.CONCLUSIONS: The agroforestry system is a preferential approach of forestry schistosomiasis control in plateau hilly schistosomiasis-endemic areas, which not only achieves snail control effects, but also promotes economic development and ecological construction in poor hilly areas.
