Abstract

OBJECTIVE

To evaluate the snail control effect and eco-economical benefit of the forest for snail control and schistosomiasis prevention in mountainous regions.

METHODS

From 2006 to 2010, the retrospective survey, field inspection and family interview were adopted to collect the data of snail status, and the economic income and ecological environment of local region in rice paddy, seedling bed, irrigation channel and kaleyard channel in Sanying Village, Eryuan County, Yunnan Province, where the Flourishing Forest and Controlling Snails Project was implemented.

RESULTS

After the implementation of the project, compared to 2006, the snail areas in rice paddy, seedling bed, irrigation channel and kaleyard channel in 2010 reduced by 70.5%, 91.0%, 49.7%, and 58.8%, respectively; the occurrence rates of frames with living snails dropped by 81.6%, 97.2%, 84.4% and 87.9%, respectively; and the average densities of living snails dropped by 79.0%, 97.8%, 86.0% and 93.6%, respectively. The economic income of farmers and ecological environment improved obviously.

CONCLUSIONS

The forest for snail control and schistosomiasis prevention in mountainous areas not only has an obvious effect on snail control, but also can yield significant economic and ecological benefits.

目的

评估山区控螺防病林的控螺效果及生态经济效益。

方法

2006年至2010年，采用回顾性调查、实地考察和入户访谈等方法，收集云南省洱源县三营村实施“兴林抑螺”项目的稻田、秧田、灌溉渠道和菜园渠道的螺情数据以及当地的经济收入和生态环境数据。

结果

项目实施后，与2006年相比，2010年稻田、秧田、灌溉渠道和菜园渠道的有螺面积分别减少了70.5%、91.0%、49.7%和58.8%；活螺框出现率分别下降了81.6%、97.2%、84.4%和87.9%；活螺平均密度分别下降了79.0%、97.8%、86.0%和93.6%。农民经济收入和生态环境明显改善。
