LUCC Remote Sensing Monitoring on Manwan Dam Immigrant Settlement Area

Based on the application of remote sensing technique, integratedly considering field investigation background, the paper selects Man-Wan Dam Immigrants Settlement area as the case study to analyses and explore local LUCC. Concretely, by use of the Landsat TM satellite images in different time of 1988, 1996 and 2000, Man-Wan Dam Immigrants Settlement land cover condition were monitored, and data analysis was completed on land cover changes in class composition and spatial distribution. The results shows that, with the Dam setting up, land cover changes has its characteristic in the mountain Immigrants Settlement area. The behavior is that mountain slope dry land mix with other cover types is of dominance relative to other cover classes, and shrubbery cover area reduces rapidly while dry land mix with other cover types increase quickly. Integrated research associated with field investigation, some primary conclusion can be made like that, in mountain Immigrants Settlement area, the main reason of LUCC comes from the limit of the mountain natural conditions; another drive may be the lag of land use management manner by man-made action. So it is necessary to enhance land use plan and management of Dam Immigrants Settlement area in Lancang River basin, prompt local social sustainable development.
