Abstract: The purpose of this study is to develop an information system for evaluating intensity of land use in development zone,so as to make the evaluating processes modeled and automated.After analyzing the requirement of land use intensity evaluation,database and software architecture and some key technologies such as 3D theme mapping,parsing engine of computing expression,integrative storing of multi-type data were designed according to requires of software engineering.The software was developed using the ArcGIS Engine Developer Kit and C# development language and was triumphantly applied in the case of land use intensity evaluating of Wuhan East Lake High-Tech Development Zone.It has been proved that the design methods and key technologies resulting in high efficiency and high-quality in the software should be introduced.
