Guizhou Provincial First Surveying and Mapping Institute，Guiyang， Guizhou Province， 55oooo China Abstract：Based on thelanduse situation 1990 to 2O2O from in Guiyang City，the spatiotemporal differentiation index Was used to study the spatiotemporal changes in land use in the study area.The ecological environment index was used to quantitatively analyze its ecological environment quality，and the relationship between land use types andregional ecological environment changes was studied.Theresults show that：Firstly，theconstruction landarea in the research area has been increasing year by year，with a total growth of 373.79km2 Due to urban expansion and development，the construction landarea has doubled in the next 1O years，while the water area has shown a trendof slow growth followedby fast growth.Thecultivatedlandand graslandareas havesignificantly decreased， while the forest andunused land areas have relatively small changes; Secondly，theconstruction land in Guiyang City is of high-speed change type（expansion index of5.21），the water area is a rapidly changing type （expansion index of 1.20），and the cultivated land and forest land areoflow-speed change type （expansion index of0.2O and 0.03，respectively）.Thirdly，theecological environment index shows afluctuating trend offirst increasingand then decreasing.Due to the rapid development of urban construction，the ecological environment index in the central urban area continues to decline，while the ecological environment in other districts and counties remains stable or has increased to some extent.The regional ecological environment index is positivelycorrelated with thecharacteristics of forest area changes.
