To provide credible data for empirical model,a method of calculating the weighted average gray value of compartment area was designed in this paper.It worked especially when the compartment area was as large as pixel.The GeoTIFF form was adopted as the RS data type.The Matlab software was used to read and store RS image.The pixel was divided into smaller units to calculate the area of spackle in each pixel by counting the amount of the units.

：为了给遥感反演模型提供可靠数据，该文设计了一种按面积加权计算不规则图斑遥感影像灰度值的方法，特别是当图斑面积接近像元大小的时候；遥感数据采用被广泛支持的GeoTIFF格式，使用Matlab将遥感影像的灰度信息及元数据读取并存入数据库中；通过将像元分解成更小的单元，统计各像元在图斑内小单元的个数，计算图斑在各像元所占的面积，按照面积加权的方式计算得到图斑的平均灰度值。
