东北地区辐射资源栅格化信息系统的建立
ESTABLISHMENT OF GRID INFORMATION SYSTEM OF RADIATION RESOURCE IN NORTHEAST OF CHINA
【摘要】 借助GIS平台和DEM数据 ,生成东北地区 1km× 1km经度、纬度、海拔高度、坡度、坡向数据库。利用 1960年~ 1990年累年月平均气候资料 ,采用气候学方法计算了东北地区 189个气象台站总辐射、直接辐射、PAR和地表有效辐射的月值和年值 ;并用极轨气象卫星资料处理软件和VB6 0语言处理了 1992年辽宁省 5月~ 8月的NOAAAVHRR数据 ,得到了辽宁省 5月~ 8月月均 1km× 1km网格的地面反射率数据。在此基础上 ,分省建立了各种辐射值与宏观地理因子 (经度、纬度、海拔高度 )的三维二次空间分布模式。半理论半经验地定量分析了坡度坡向对总辐射和PAR的影响 ,最终建立了东北地区辐射资源栅格化信息系统。
【Abstract】 By employing GIS, VB6 0 and 1km×1km DEM of northeast of China ,1km×1km databases in aspects of longitude、latitude、altitude、slope were established. Using climate data from 1960 to 1990, monthly and annual data of total radiation, direct radiation, PAR and effective radiation of earth surface of 189 station in northeast of China was calculated. 1km×1km monthly surface albedo of Liaoning province from May to August in 1992 was calculated using NOAA AVHRR Data dealt by the Polar orbit satellite data processing software and VB6 0. On the base of the work, the spatial distribution model for each province of northeast of China was established in terms of different geographical dimensions as longitude, latitude and altitude. The influence of slope and aspect to total radiation and PAR was analyzed in empirical and theoretical perspectives. Finally, the grid information system of radiation resource in northeast of China was established.
