Abstract: Based on spatial statistical analysis and Web-MIS theory，Web system has been improved，introducing Web-MIS in Web system loosely coupled system statistical model and spatial statistical analysis concept，the system was developed using JZEE software.Java technology was integrated in the system to make Web applications more and more dynamic and agility，to achieve loosely coupled Web system performance.It has good application prospects.As forestry survey information platform an example，mathematical model of forestry survey and Web-MIS loose coupling system algorithm were designed.On this basis，forest resources management system was established.Input，update，query，statistics and other functions of the Web operating environment for forestry survey data were implemented.Real-time interaction effect of user and computer was achieved.
