5. CONCLUSIONS 
The land-use dynamic monitoring system of Guangdong 
Province is mainly built for the production, so the system 
designing focuses on the algorithms practicality and functions. 
Due to the influence of the resolution of remote sensing image 
and other factors, the accuracy of change polygon is different. 
In order to meet the actual application, the limit values may be 
adjusted for the change polygon detected in the system. The 
automatic detection of the change polygon is regarded as a kind 
of the supplemental measures for land use dynamic monitoring 
so as to improve the production efficiency. The system has 
gained preliminary application in the production, and be 
expected to obtain more reliable and more accurate change 
polygon with the improvement of the data source, detection
