Abstract: According to the problem that the calculating amount is large in multi-source data fusion, the paper designs and develops the calculating and analyzing software on data fusion based on evidence theory. Firstly, it proposes the structure of this software, and then analyzes and explains its function. Finally, considering multi-source water quality monitoring data as the target, the paper proves that it can reduce the calculating amount by using the software. In addition, it has convenient, high-efficient and all-purpose characteristics

Key words: D-S theory; Data fusion; Application software development
