摘    要:目的分析诺阿卫星改进型甚高分辨率辐射仪归一化差值植被指数(NOAAAVHRRNDVI)与疟疾流行地区分布的相关性,探讨将遥感技术应用于海南省疟疾监测的可行性。方法收集1995年2月至1996年1月海南省各地疟疾发病资料,并通过其间海南省NOAAAVHRRNDVI10日复合遥感影像片获取各地各类NDVI指标值,计算发病率与相应NDVI值的相关系数。结果海南省各地疟疾年发病率与当地年均NDVI值、年均最大NDVI值、年均NDVI>145的区域面积构成比、NDVI>135的月份数呈显著正相关,与年均NDVI<145的区域面积构成比呈负相关。疟疾高发区分布与月度NDVI>145且持续9个月以上的地区分布较为一致。结论海南省疟疾地区分布与当地NDVI值有相关性,可以进一步考虑应用NDVI值进行疟疾监测的可行性。

Abstract:Objective To explore the relationship between malaria epidemics and NOAA-AVHRR NDVI. Methods Data on malaria were collected in all 19 counties in Hainan province from Feb,1995 to Jan,1996. Values regarding normalized difference vegetation index (NDVI)-related indicators including mean and maximum values of NDVI, the area proportion of NDVI values of 145-and 145+, months with NDVI values of 135+,140+, 145+, 150+ of these counties in this period were all extracted from NOAA-AVHRR images, using ERDAS 8.5 software. The coefficients of correlation of malaria incidences and these NDVI-related indicator values were then calculated with SPSS 11.0 . Results The incidence of malaria showed positive correlations to mean and maximum values of NDVI, the area proportion of NDVI values of 145+ and months with NDVI values of 135+,140+, 145+, 150 + respectively, but having negative correlation to the area of NDVI values of 145-. The malaria epidemic regions were in accordance with those regions that the NDVI values of 145+ were continueing for 9 months or more. Conclusion Malaria prevalence was associated with NOAA-AVHRR NDVI value which could be considered to be use for malaria surveillance in Hainan province.
Keywords:Malaria  Normalized difference vegetation index  Remote sensing
