Abstract: BiodiversityMapping is an integrative biodiversity assessment software. Different from other general or professional biodiversity software, this package combines the calculation of various diversity measures with geographic information system (GIS). The main techniques involved in this package are the visual programming method and component development. These two techniques are widely used in rapid application development, especially in GIS projects. Shape View Objects, a free Delphi-based GIS component package designed by Ecological Software Solutions, is the key to the combination. BiodiversityMapping was developed with visualized software development tools and can work under Windows 98/NT operating systems. It has a user-friendly interface and a size of about 6 MB. Thirty-seven measurements of α and β diversity, which can be plotted on a GIS map, are included in the package. With BiodiversityMapping, we calculated and plotted Shannon-Wiener indices of Carabus insects collected from 11 habitat types of Xiaolongmen, Liyuanling and the top of Dongling Mountain, Beijing. Right-tailed Sum Diversity Ordering on these sites was also deployed. These calculations give graphical explanations for the species diversity of Dongling Mountain in an intuitive way. The computer aided analysis on Dongling Mountain shows that BiodiversityMapping, which can calculate many diversity measures easily and accurately, is a powerful tool for biodiversity assessment.
