RESUMEN

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.

RESUMEN

Relevant projects carried out within the Yangtze River economic belt on the impact of schistosomiasis epidemic and transmission are important issues for ecological priority in the process of implementing the strategy. The key problems of schistosomiasis epidemic risk,epidemic happening repeatedly,difficulty of rehabilitating Oncomelania hupensis snail control and schistosomiasis prevention forest,lag of evaluation system and platform construction,lack of basic research,et al. were ana-lyzed in the Yangtze River economic belt taking ecological priority as the basis in this paper. Then corresponding countermea-sures to these challenges were put forward so as to provide the reference for the national forestry schistosomiasis control pro-grams,which include:execution of the comprehensive prevention and control strategy,scheming of the new round of forestry schistosomiasis control programs,strengthening schistosomiasis prevention and control,promoting productivity in existing forest-ry to consolidate and improve the achievements of previous forestry schistosomiasis control programs,and promoting the intensi-ty of technological innovation to improve the technological level of forestry schistosomiasis control programs.

RESUMEN

Objective To real?timely monitor the environment in the forestry schistosomiasis control project(CFSCP)area and to early warn the status of Oncomelania hupensis snails in the schistosomiasis endemic area. Methods Based on ArcGIS Engine 10.1 software,the Geographic Information System(GIS)platform of the forestry schistosomiasis project of real?time mon?itoring,early warning and emergency management in Renshou County,Sichuan Province,was designed and established. Re?sults The functions of the platform mainly included real?time monitoring of the environment in CFSCP area,and early warning of the crisis status of O. hupensis snails,as well as editing the map of snail distribution,query,spatial analysis and other GIS functions. Conclusion This platform could provide the scientific support to the forestry administrative department of the CF?SCP area.
