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/hm, followed by the"walnut + chili"pattern (annual economic benefits of 120 000 Yuan/hm) and the "walnut + vegetables"pattern (annual economic benefits of 105 000 Yuan/hm). 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.

目的

探讨不同农林业系统在云南省高原山区血吸虫病流行区控制钉螺的效果，为高原山区农林业血吸虫病防治工程建设提供参考。

方法

2010年在云南省洱源县的钉螺孳生农田建立了不同农林业系统的抑螺林地试验区，并于2018年对其经济效益和抑螺效果进行调查。此外，建立模糊综合评价模型筛选综合效益高的农林业系统。

结果

共建立了14种不同农林业系统的抑螺林地试验区。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）。在包括“核桃+辣椒”模式、“核桃+烟草”模式和“核桃+大蒜”模式在内的8种农林业系统中未检测到钉螺；然而，在其他类型的系统中发现了不同密度的钉螺。模糊综合评价表明，“核桃+大蒜”模式综合防治效果最佳，其次是“核桃+辣椒”模式和“核桃+烟草”模式，而纯草地模式对钉螺控制无效果。
