ABSTRACT
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.
