摘要： 目的  了解林业血防工程对钉螺糖原、蛋白质含量及氨基酸组成的影响。 方法  在长江安徽段上、中、下游各选择一个实施林业血防工程的环境，并在其邻近选择一个有螺草滩作为对照观察点，分别采集一定数量钉螺，测定并比较不同环境钉螺糖原、蛋白质含量及氨基酸组成。 结果  3个观察试点林地环境钉螺的蛋白质含量分别较相邻近的对照草滩环境钉螺蛋白含量降低21.5%、11.5%、15.0%；糖原含量分别降低5.5%、5.7%和5.3%。3个试点中，安庆和铜陵林地钉螺的氨基酸含量分别较邻近草滩（芦苇滩）钉螺低47.1%和51.5%，而无为林地和草滩钉螺氨基酸含量基本接近。 结论 林业血防工程对钉螺生物体的营养成分产生一定的影响，造成钉螺营养不良，可能是螺口密度下降的原之一。

Abstract:

Objective To understand the influence on the content of protein, amino acid and glycogen for snails in project of afforestation for schistosomiasis control. Methods  One spot with the project of afforestation for schistosomiasis control and one spot with marsh (reed beach) nearby were selected in the upstream, midstream and downstream regions along the Yangtze River in Anhui Province, respectively. Snails in the spots were collected to detect the content of protein, amino acid and glycogen. Results  The content of protein for snails in woodland was 21.5%、11.5%、15.0% lower than that in grass land in the three spots, and glycogen was 5.5%、5.7% and 5.3% lower than that in grass land, respectively. The content of amino acid for snail in woodland was 47.1% and 51.5% lower than that in grass land in Anqing and Tongling spot, and little difference in Wuwei spot. Conclusion  The project of afforestation for schistosomiasis control had certain influence on nutritional composition of snails, and caused malnutrition for snails. It might be one of reasons for the decline on snail density.
