【摘要】：三峽工程運(yùn)行是否導(dǎo)致長江中下游血吸蟲病蔓延問題引起了廣泛關(guān)注。2003~2010年先后在洞庭湖區(qū)布置了26個(gè)螺情監(jiān)測站,進(jìn)行跟蹤監(jiān)測。監(jiān)測數(shù)據(jù)表明,2014年與2003年螺情比較,洞庭湖洲灘有13個(gè)監(jiān)測點(diǎn)未查到釘螺,9個(gè)有螺監(jiān)測點(diǎn)活螺平均密度降低了96.27%;2014年有螺點(diǎn)占總監(jiān)測點(diǎn)的34%,有螺洲灘面積和分布范圍正在快速縮小,洲灘釘螺向垸內(nèi)擴(kuò)散機(jī)率大幅減小。
[Abstract]:Whether the operation of the three Gorges Project leads to the spread of schistosomiasis in the middle and lower reaches of the Yangtze River has aroused widespread concern. From 2003 to 2010, 26 monitoring stations were placed in the Dongting Lake region to track and monitor the schistosomiasis. The monitoring data show that the snail situation in 2014 is compared with that in 2003. Oncomelania hupensis has not been detected at 13 monitoring points in Dongting Lake, and the average density of live snails in 9 snail monitoring points has been reduced by 96.277.In 2014, the snail points accounted for 34 percent of the total monitoring points, and the area and distribution of the snails at the Luozhou beach are shrinking rapidly. The probability of snail diffusing into embankment is greatly reduced.
