Analysis of land use change in Da'an city based on GIS and RS

Land use change analysis is based on land use change,analysis and prediction of regional future land use change trend.Based on Landsat remote sensing data in 1986,2000 and 2018,this paper conducts quantitative analysis and research on land use situation of Da'an city through calculation of dynamic attitude and transfer matrix.The results show that the main types of land use in Da'an city are grassland,cultivated land and water area,which account for 75%of the total area of the city,while construction land,forest land and other land only account for 25%.During the past 32 years,the land use type of Da'an city changed obviously,and the area of cultivated land and residential land increased obviously.The area of natural grassland,forest and water decreased,while the area of other land decreased after increasing.The area of different land types increases or decreases mainly because of their mutual transformation,with grassland and other types of transformation the most frequent.The results of this study can be used for land structure adjustment of Da'an city and provide reference for environmental governance and future urban development.
