摘要
在深入分析有效辐射理论公式的基础上,利用日射站和常规气象站观测资料,确定有效辐射拟合的经验函数式;利用数据集群技术,建立一系列不同时空尺度的有效辐射估算模式;通过误差分析,最终确定适用于全国范围有效辐射计算的拟合模型;采用确定的有效辐射拟合模型,结合黄河流域及其周边常规气象站观测资料,对黄河流域1960~2000年有效辐射进行计算,利用ArcGIS将站点有效辐射拟合结果进行空间内差,获得黄河流域有效辐射的空间分布。
Under thoroughly analyzing on the theoretic formulation of effective radiation as well as referring similar studies carried before, a series of effective radiation models of different temporal and spatial scales were developed, with the technique of data integration. The accuracy of different models was analyzed thoroughly. Monthly effective radiation simulation models for China were selected. By virtue of the selected models together with routine meteorological data of 164 stations, in and around the Yellow River basin, monthly effective radiation of the Yellow River basin from 1960 to 2000 were estimated. Using the interpolation function of ArcGIS, spatial distribution of effective radiation of the Yellow River basin was generated.
