中文摘要：

将DEM信息与遥感影像信息有效结合是实现信息强化表达的有效途径,本研究通过在所选梯田实验样区布设实验样点,获得该点所处梯田田面的田面宽度值及由DEM数据求取的坡度值,基于两者关系进行了相关拟合、反演、分类及假彩色合成实验,强化了梯田信息的表达效果。结果表明：通过DEM与遥感影像数据进行地物的联合特征分析,可有效提高研究对象的信息量,为实现梯田信息的强化表达提供了一种新的途径。

英文摘要：

It is an effective way to enhance the expression of information by combination of DEM and remote sensing image information. In this research,the terrace width and the slope value of the DEM data were obtained by setting the experimental sample points. Based on the relationship between terrace width and slope value,fitting,inversion,classification and false color composite were carried out so that the expression of the terrace information was enhanced. The results show that the combined feature analysis of DEM and remote sensing image data can improve information content and provide a new way to finish terrace information enhancing.
