湖北省是我国血吸虫病疫情最严重的区域之一,是我国血防工作的重点区域。近些年来,虽然湖北省的血防工作取得了显著成就,但疫情仍时有发生,实现血吸虫病传播阻断的目标还有大量工作要做。由于钉螺是血吸虫病传播的唯一中间环节,灭螺、控螺就成为血防工作最重要、最有效的途径之一。鉴于此,对湖北省近期钉螺的地理分布进行了详细的制图与空间分析,对于确定灭螺、控螺的重点区域具有明显的指示意义。首先收集整理了湖北省血吸虫年报及各县市的查灭螺资料,并利用软件ArcGIS软件将钉螺螺情数据导入数据库,建立湖北省钉螺地理信息基础数据库,绘制了钉螺空间分布图,然后对钉螺分布的空间特征进行了分析。主要结论如下:省内钉螺及钉螺易感地带沿长江中游、汉江两岸以及与两江相通的湖泊洪泛区分布,并呈明显的粗带状;各流行区类型(湖沼垸外亚型、湖沼垸内亚型和山丘型类型)钉螺地理空间分布具有明显的区域差异;江湖洲滩为钉螺主要孳生环境,总体沿两江呈不连续窄带状分布,沟港环境钉螺分布范围广而离散。 Hubei Province is one of the areas with the most serious epidemic situation of schistosomiasis in our country and is the key area for our country’s blood-disease prevention work. In recent years, although remarkable achievements have been made in blood and disease prevention in Hubei Province, the epidemic still occurs from time to time. There is still a great deal of work to be done to achieve the goal of blocking the transmission of schistosomiasis. As snails are the only intermediate link of schistosomiasis transmission, snail control and snail control have become one of the most important and effective ways to prevent blood diseases. In view of this, a detailed mapping and spatial analysis of the geographical distribution of snails in Hubei Province in recent years is of great significance in determining the key areas for snail control and snail control. Firstly, the annual report of schistosoma japonicum in Hubei province and the information of check snails in various counties and cities were collected and collected. The data of snails were imported into the database by software ArcGIS software. The database of snail geography information in Hubei Province was established and the spatial distribution of snails was drawn. The spatial characteristics of distribution were analyzed. The main conclusions are as follows: In the province snail and snail susceptible zone along the middle reaches of the Yangtze River, the Hanjiang River and the two rivers are connected with the floodplain floodplain distribution, and showed a rough band; the prevalence of the type of area There was a significant regional difference in geosynaptic distribution of Oncomelania hupensis. The rivers and lakes were the main breeding habitat for Oncomelania hupensis, which distributed discontinuously and narrowly along the two rivers. The distribution of Oncomelania hupensis in the ditch-harbor environment was wide and disperse.
