以血吸虫病典型流行区湖北省公安县为研究区,以行政村为基本研究单元,通过空间自相关和分组分析方法探究公安县钉螺空间分异规律,进而运用逐步回归、地理加权回归和地理探测器模型探讨公安县钉螺分布影响因素及其交互作用。结果如下: ( 1)公安县钉螺密度具有较强的空间集聚特性,形成2个较大的热点集聚区;综合考虑公安县钉螺密度水平和空间连接性,将公安县划分为高、中、低3个钉螺密度区。( 2)人口密度、水网密度、水田比例、春季NDVI和秋季NDVI是公安县村级尺度钉螺密度主要影响因素,其影响效应具有空间异质性。( 3)从整个研究区来看,两因子交互作用均产生非线性增强( NE),即两因子交互作用于钉...

Schistosomiasis is a parasitic disease that threatens human health and impedes socioeconomic development in the Oncomelania hupensis endemic areas. Oncomelania is the only intermediate host of schistosoma japonicum,and therefore to analyze the spatial-temporal distribution patterns of Oncomelania and their influencing factors is of vital importance for Schistosomiasis control. Hubei province has long suffered from the threat of the Schistosomiasis. This paper selected Gongan county,which is a typical Oncomelania hupensis endemic area,to study spatial disparity of Oncomelania density with the m...
