肥城市土地利用变化及驱动力分析

以肥城市为研究对象,利用最大似然监督分类法对肥城市1994年、2002年的landsat TM和2017年的landsat OLI遥感影像进行土地利用分类,依据土地利用动态度、土地利用转移矩阵对肥城市土地利用变化进行分析。实验表明:近23年来,肥城市土地利用变化明显,其中建设用地面积增加54.22 km^2,林草地面积增加80.87 km^2,耕地面积减少107.02 km^2、水体面积减少17.28 km^2;同时表明在经济驱动、政策引导以及人为因素的影响下肥城市土地利用程度会进一步加深。

Analysis of Land Use Change and Driving Force in Feicheng

Taking feicheng city as the research object,the landsat TM in 1994,landsat OLI remote sensing images in 2002 and landsat OLI remote sensing images in 2017 were classified into land use categories by the maximum likelihood supervised classification.The land use change in feicheng city was analyzed according to land use dynamic attitude and land use transfer matrix.The experiment shows that in the past 23 years,the land use of feicheng city has changed significantly,among which the construction land area increased by 54.22 km^2,the forest and grassland area increased by 80.87 km^2,the cultivated land area decreased by 107.02 km^2,and the water area decreased by 17.28 km^2.At the same time,it indicates that the land use of feicheng city will be further deepened under the influence of economic drive,policy guidance and human factors.
