Land use changes of Xiangshan County based on RS And GIS

摘要

Xiangshan County is one of the most important areas in Zhejiang Province. The land use changes interpretion and its changing rules are the main aims of the paper. Firstly, for the classification system was the foundation of the study, it had to be built. Secondly, the tasks were the collection and preprocessing of the high resolution remote sensing images in 2009 and 2012. Thirdly, the interpretation standard was established based on the different spectrum features according to the different land use types in remote sensing images. Fourthly, the interpretation of RS images in 2009 and 2012 were done respectively, and then the land use data of Xiangshan county in different times were got. At last, the changing rule of different land use types was analyzed. Remote Sensing (RS) and Geographic Information System (GIS) were used adequately during the whole process. Remote sensing can provide abundant and real-time information, and Geographic Information System has powerful functions in data processing and spatial analysis, so the combination of RS and GIS has perior advantages compared with the traditional methods, and is highly effective in analyzing the land use/land cover changes in study area.
