摘要
为阐明三峡建坝后水位变化对长江安徽段滩地开发利用及其对血吸虫病流行的影响 ,对长江安徽段江湖洲滩血吸虫病流行区人文、滩貌结构与植被分布、滩地开发利用以及钉螺分布等进行现况调查 ,结合三峡大坝工程对长江安徽段水位变化影响进行综合分析。结果长江安徽段江湖洲滩 16 .2 8%的滩地面积被农业开发利用 ,7.88%的滩地面积被开发为水产养殖 ,有 10 %左右的滩地被翻耕植树 ,已被农业开发的江洲湖滩 ,主要农作物有水稻、棉花、油菜、小麦。三峡建坝后长江中下游秋季水位将有所下降 ,使滩地露滩时间提前。表明三峡工程将有利于滩地农作物的播种 ,使滩地可开发耕种的面积扩大而有利于消灭滩地钉螺。
To clarify the impact of water level changes after The Three Gorge Dam construction on the exploitation and utilization of marshland in Anhui Province along Yangtze River, and the impact on prevalence of schistosomiasis. The data of population, constitution of marshland, distribution of vegetation, exploitation and utilization of marshland, distribution of snail were surveyed, and the impact on water level after Three Gorge Dam construction was analysed synthetically. The result showed that in Anhui Province, about 16.28% of the areas of marshland have been exploited and utilized by agriculture, about 7.88% of the areas have been utilized for aquastics, about 10% of the areas have been used for planting trees. The main crops grown were rice, cotton, oil crops and wheat. Water level in autumn will decrease in the middle and low part of Yangtz River after The Three Gorge Dam construction, the surface of marshland will emerge earlier in the year. It is suggested that the Three Gorge Dam construction will be beneficial for cultivating crops in marshland and areas of cultivable will enlarged to be beneficial for eliminating the snail of marshland.
