摘　　要：利用DMSP/OLS NTL遥感影像数据,采用相关分析和回归分析探测灯光强度与GDP的密切程度.实验结果发现:在省级尺度下,多年DMSP/OLS NTL数据与GDP存在显著相关,相关系数达到0.956 4;为了探测DMSP/OLS NTL数据对小尺度的展布效果,进一步逐年以地级市尺度预测县级市尺度GDP并与统计局公布的GDP对比,其总量吻合程度高,说明DMSP/OLS NTL数据可以作为GDP网格化表达的辅助数据,最后借助DMSP/OLS NTL构建了福建省890m×890m尺度的GDP网格化影像图.In the study the DMSP/OLS NTL remote sensing image data is used, correlation analysis and regression analysis are introduced to detect the correlation between the intensity and GDP.The experi- mental results show that in the provincial scale, DMSP/OLS NTL data with GDP exists significant correlation, the correlation coefficient is 0.9564.To detect DMSP/OLS NTL data distribution effect of small scale, further to predict county level city scale scale GDP and the comparison of the bureau of statistics released by the GDP, the total match degree is high,which shows that DMSP/OLS NTL da- ta can be used as GDP grid of secondary data,findly the GDP of the Fujian Province 890 m）〈 890 m grid image is set up with the DMSP/OLS NTL.
