Study on land use and land cover change in Tianfu new area based on RS&GIS

Land use has taken on more significance as a result of population increase and urbanization, particularly in emerging nations. The management of natural resources like water, vegetation, and arable land is made easier by the direct observation of land use changes in particular locations at different periods through the use of land categorization photographs. This investigation of land use changes and their features in Tianfu New Area, Chengdu, is based on land satellite imagery from 2011 and 2021. Process the data, extract the land use Stochastic matrix, and do a thorough analysis using remote sensing and GIS tools. The findings show that there are five different forms of land usage in Tianfu District between 2011 and 2021: arable land, construction land, unused land, forest land, and water area, with arable land continually making up the greatest share of the overall area. The conversion of arable and forest land, along with relatively minor changes in the water area, has resulted in the highest rise in the area used for building among all other forms of land use. Additionally, there are large geographical disparities in land use changes, with the north and south of Tianfu New Area experiencing fewer major changes than the south.
