Impact of Apply Remote Sensing Technical to Analysis Flooding Area in 1998 for Potential Diffusing of Oncomelania hupensis in Yangtze River Drainage Basin

摘要

Through many years of schistosomiasis control in China, the Oncomelania hupensis of the snail ecology and habitats distribution were understood. Due to the distribution of the snail habitats could be display by remote sensing image reality and impersonality, the study was performanced the forecast on the potential diffuse of the snail areas with unusual flooding along with Yangtze River drainage basin of schistosomiasis endemic area in 1998 by means of remote sensing image manipulation, the result was as follows.nArea of Three Gorges of Yangtze River: The area of Three Gorges of Yangtze River that was deal with by remote sensing image manipulation, it did not showed the Oncomelania hupensis snail habitats on the image manipulation and also confirmed by land investigate late. However, another kind of snail with the mane of Tricula sinica was discovered, in which the ecology habitats is the same with the Oncomelania hupensis snail.
