摘要：目的为高原缓丘区兴林抑螺提供造林模式。方法在已营建抑螺防病林(示范区)和未营建抑螺防病林(对照区)样地上按原利用方式调查钉螺,分析营造抑螺防病林对钉螺的影响。结果对照区活螺框出现率和活螺密度分别为26.81%和0.94只/0.1m2,8类土地利用方式环境钉螺活螺框出现率和活螺密度差异均有统计学意义(F=11.29、12.71,P均<0.01),渍水低地、水田和水旱轮作地钉螺数量较大,旱作农地和林地钉螺数量较少。与造林前相比,抑螺防病林营造5年后活螺框出现率和活螺密度降低幅度在62.70%～89.98%和74.03%～94.00%。与对照区相比,示范区活螺框出现率和活螺密度分别下降了52.04%～87.36%和52.20%～95.45%。结论高原缓丘区抑螺防病林的营建可有效控制钉螺。
Objective To provide better afforestation/forestation patterns for snail（Oncomelania hupensis） control in gentle hilly region in China.Methods The snails were investigated and the effects of afforestation on snail community were analyzed at the plots with or without snail controlling forest.Results The community of snails exhibited a middling variation at the area with-out snail controlling forest（control area）,where the living snail frame occurrence（LSFO） and mean snail density（MSD） were 26.81% and 0.940 snails per 0.1 m 2,respectively.There were significant differences in LSFO（F =11.29,P 0.01） or MSD（F = 12.71,P 0.01） among the eight land use types at control area.Higher snail numbers occurred in lowland,paddy field and paddy-upland rotation land,whereas the lower were in dry farming land and plantation.After 5 years of plantation,LSFO and MSD re-duced by 62.70%-89.98% and 74.03%-94.00% under 5 land use types,respectively.LSFO and MSD reduced by 52.04%-87.36% and 52.20%-95.45%,respectively at the demonstration area compared with those at control area.Conclusion Afforestation/forestation would effectively reduce snail community irrespectively of land uses at gentle hilly region in plateau.
