In order to optimize the soil environmental monitoring process, an integrated mining model framework was presented on the basis of data warehouse and workflow mining technologies for the first time. This integrated mining model is made up of a data model and an integrated mining model. The data model is the data source for the integrated mining which is built by using Snow Flake Schema. The integrated mining model consists of local mining and global mining. That is to say, firstly, monitoring cell mining, point mining and monitoring data mining are fulfilled respectively, then global mining model is run to opimize the monitoring process. The paper brings forward how to build up these models and the framework, and what variables should be delivered. This study provides a guideline for enhancing work efficiency of soil environmental monitoring, for expanding the functions of Lab Information System(LIMS), and for building the soil environmental monitoring expert system in the future.
