目的 了解南水北调东线工程源头地区钉螺分布及其对调水安全的影响.方法 每年春季采取系统抽样结合环境抽查法对东线工程源头地区进行钉螺分布调查,同时选择江都水利枢纽泵站消力池滩地定点监测钉螺扩散.结果 2006-2009年东线工程源头地区查出钉螺面积分别为256.11、184.55、164.92 hm~2和121.16 hm~2;感染性钉螺面积分别为8.3、1.0、1.0 hm~2和0 hm~2;活螺密度也呈逐年下降趋势.Google Earth地图显示东线工程源头地区钉螺主要分布在夹江和芒稻河.对江都泵站消力池滩地定点监测发现局限性低密度扩散钉螺,分析原因为引河疏浚工程建筑垃圾携带所致.结论 南水北调东线源头地区存在钉螺扩散的风险,因此有必要长期开展监测和控制.
目的 瞭解南水北調東線工程源頭地區釘螺分佈及其對調水安全的影響.方法 每年春季採取繫統抽樣結閤環境抽查法對東線工程源頭地區進行釘螺分佈調查,同時選擇江都水利樞紐泵站消力池灘地定點鑑測釘螺擴散.結果 2006-2009年東線工程源頭地區查齣釘螺麵積分彆為256.11、184.55、164.92 hm~2和121.16 hm~2;感染性釘螺麵積分彆為8.3、1.0、1.0 hm~2和0 hm~2;活螺密度也呈逐年下降趨勢.Google Earth地圖顯示東線工程源頭地區釘螺主要分佈在夾江和芒稻河.對江都泵站消力池灘地定點鑑測髮現跼限性低密度擴散釘螺,分析原因為引河疏浚工程建築垃圾攜帶所緻.結論 南水北調東線源頭地區存在釘螺擴散的風險,因此有必要長期開展鑑測和控製.

Objective To understand the distribution of Oncomelania hupensis snails in source areas of the east route of Southto-North Warter Diversion Project and evaluate the effects of the snails on the safety of water transfer.Methods The investigation of snail distribution was carried out in the source areas of the east route of South-to-North Warter Diversion Project every spring.The method of the random sample combined with environmental sample was used for the field investigation.The beach land in the stilling pool of Jiangdu Pumping Station was selected as a surveillance site to observe the snail spread.Results The areas of the snail habitats and infected snails were 256.11,184.55,164.92,121.16 hm~2 and 8.27,1.0,1.0,0 hm~2 respectively in the source areas of the east route of South-to-North Wafter Diversion Project from 2006 to 2009.The densities of living snails had a downtrend,too.Google Earth showed that the areas of snail habitats distributed mainly in the Jiajiang River and Mangdao River in the source areas.The snail habitats were detected in the beach land in the stilling pool of Jiangdu Pumping Station.The research results showed that the snail spread related to the wastes from the river of drawing water.Conclusion There are the risks of snail spread in the source areas of the east route of South-to-North Wafter Diversion Project,so that the long-term surveillance and control on the snails is very necessary.
