| 摘 要： | 目的 利用遥感、地理信息系统和空间统计学方法，分析广州市登革热疫情与空间地理环境之间的关系。方法 利用遥感和地理信息系统技术用于多源地理空间环境数据的获取，Spearman法和多重回归法分析登革热疫情与地理环境因子之间的关系。结果 登革热疫情与土地利用类型、水体指数、地表温度、人口和国内生产总值间呈高度显著正相关，其中与夜晚地表温度和人口的相关系数分别为0.699和0.705。建立了登革热疫情与人口、夜间地表温度、土地利用类型之间的多重线性回归方程，R2=0.278，整体F检验P=0.001，回归方程具有统计学意义，其中人口对登革热疫情贡献最大。结论 登革热疫情与人口、经济等社会环境和温度、土地利用类型等自然环境密切相关，在今后的登革热防控中，应重点关注地理空间环境中人口密度和地表温度对疫情的影响。

| Abstract: | Objective To analyze the relationship between dengue fever epidemic and spatial geographical environment in Guangzhou,Guangdong province.Methods Remote sensing and geographic information system technology were used for the collection of multi-source geospatial data.Spearman method and multivariate regression analysis method were used to analyze the relationship between dengue fever epidemic and geographical environment factors.Results The results indicated that dengue fever epidemic was highly significantly positive correlated with land use type,water index,land surface temperature,population and gross domestic product,and the correlation coefficients between dengue fever epidemic and land surface temperature in night and population were 0.699 and 0.705,respectively.The multivariate linear regression equation between dengue fever epidemic and population,land surface temperature in night and land use type was established.The R2 was 0.278.The overall F test had a P value of 0.001,the difference was significant.The contribution of population to dengue fever epidemic was highest.Conclusion Dengue fever epidemic is closely correlated with social factors,such as population density,economy level,and natural environment factors,such as air temperature and land use type.Therefore,it is necessary to pay attention to the influence of population density,air temperature and in the future prevention and control of dengue fever. |
