网络释义

用法例句

The software to calculate FID values using Avenue language based on Arcgis system was programmed, and then through practical calculation ofFID and its conversion mathematical relationship analysis under different contour-line interval in Baishuixi watershed, the results indicated that the FID can not only be used as the integrative and scientific measurem.

首先论述了以地理信息系统(GIS)为平台,基于分形信息维数(FID)表征地貌形态特征的原理和方法,采用Avenue语言开发了基于ArcGIS环境下地貌形态特征FID计算软件;并以长江流域白水溪小流域为例,进行了不同等高距下地貌形态特征FID的计算,通过对FID与等高距耦合关系的深入分析,结果表明:基于FID不仅可以对流域地貌形态特征进行宏观性、综合性定量表征,而且能够实现不同等高距下流域地貌形态特征的相互转换,有利于与流域形态特征相关联的水文、水土流失过程的动态模拟,同时可实现对现有地形数据的充分挖掘,填补我国大比例尺基础地理信息数据不足的缺陷。
