资源一号02 C卫星多光谱数据没有蓝色波段，给制作真彩色影像带来了一定困难。本文针对02 C卫星多光谱波段的特点，分析了常用线性模拟蓝波段影像方法，选取多景不同时相的、覆盖山地或平地的真实数据进行加权法和平均值法的对比试验，定性与定量分析后的结果表明：基于加权法生成蓝波段的真彩色模拟结果，无论是从整体色调方面，还是从典型地类的颜色方面，均优于基于平均值法生成蓝波段的真彩色模拟结果，可进一步深入研究后进行规模化应用。

It is very difficult to map natural color image using Ziyuan -02 C satellite multispectral image for the lack of blur band . This paper analyzed the common natural color simulating methods based on the characters of multispectral bands , and carried out the comparisons of weighted and average methods on several real images coving mountain or plain areas individually imaging at different phases .The results show that the weighted method performs better that the average method considering the total color and those of typi -cal land use classes , which is suggested to be applied in Large -scale after further researching .
