Abstract:

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。

English 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.
