多房棘球绦虫(Echinococcus multilocularis)的幼虫期导致罕见而致命的肝病即人类的泡型包虫病(HAE)。绦虫在狐狸(或狗类)与一些小型哺乳类动物之间以寄生虫-寄主的方式进行循环传播。中国中部一些地区的人类泡型包虫病属于地方流行病,在部分乡村的发生概率达到15%。本文研究如何利用遥感数据并基于地区景观特性获取该流行病清晰地空间危害分布图。遥感数据分析的结果显示,人类居住地附近的草地或灌木是HAE传播的一个主要危险区域,从空间分布上看,这些区域是小型哺乳动物等中间寄主的聚集处。
The larval phase of Echinococcus multilocularis results in a rare and fatal liver disease, human en bloc echinococcosis (HAE). Tapeworms circulate in a parasite-host fashion between foxes (or dogs) and small mammals. Humanoid hydatidiform encephalopathy is endemic in some parts of central China, with a probability of 15% in some villages. This article studies how to use remote sensing data and obtain a clear spatial hazard map of the epidemic based on regional landscape characteristics. The results of remote sensing data analysis show that grasslands or shrubs near human settlements are a major risk area for the spread of HAE and are spatially distributed aggregates of intermediate hosts such as small mammals.
