湖沼钉螺孳生环境分布的遥感调查研究

以试验区不同环境类型洲滩钉螺螺情与环境因子进行了调查分析，利用遥感图像编制地貌类型图，土壤类型图和土地利用类型图，在地理相关分析与主导因素分析基础上采取多图件逐步套合方法，以土地利用类型图为主，结合地面钉螺抽样调查和钉螺被动扩散等非遥感信息进行多信息复合，编制了试验区钉螺孳生环境分布图。

IDENTIFICATON OF THE DISTRIBUTION AREA OF ONCOMELANIA HUPENSIS BY REMOTE SENSING

The distribution and environmental factors of Oncomelania hupensis were investigated inthe typical swamp areas of Yangtze River.Geomorphic map, soil map and land utilizationmap ab the basic information sources were made by remote sensing images.At the sametime, on the basis of geographic correlation analysis and main factors analysis,the map ofdistribution area of Oncomelania hupensis was elaborated by using the land utilization map asa main information combined with non-remote sensing information such as Oncomelaniahupensis sampling investigation on the swamp region.
