古堰画乡景区及其周边土地利用演变研究

Research on Land Use Evolution of the Scenic Spot of Ancient Weir Painting Hometown and Its Surrounding Areas

以古堰画乡景区及其周边区域为研究对象,利用ENVI等软件对研究区2009年、2014年、2018年三个关键时点遥感影像进行研究分析。结果显示:建设用地是古堰画乡景区及其周边土地利用演变的主体和主要驱动,它引起林地、耕地、水域和未利用土地等其他用地类型相应变化。研究期内建设用地面积增加最多,其他类型用地面积均不同程度地减少。建设用地基本不向其他土地类型转化,其他土地类型虽有相互转化,但都主要向建设用地转化。影响研究区土地利用演变的主要因素包括旅游者、当地政府和村民,其中政府是最主要的推动因素。

Taking the scenic spot of Ancient Weir Painting Hometown and its surrounding areas as the research object,the paper analyzes the remote sensing images of three crucial time points in the research area in 2009,2014 and 2018 by using ENVI and other software.The results display that the construction land is the main body and main driving factor of the land use evolution in the scenic spot of Ancient Weir Painting Hometown and its surrounding areas,which causes the corresponding changes of other land types including woodland,cultivated land,water area and unused land.During the research period,the area of construction land increased the most,while the area of other types of land decreased by varying degrees.Construction land was normally not transformed to other land types.Although other land types could be transformed into each other,they were mainly transformed into construction land.There are main factors affecting the land use evolution in the research area,including tourists,local government and villagers of which the government is the most important promoting factor.
