基于支持向量机的六安市城区多源景观格局演化分析
Evolution of Landscape Pattern Analysis Based on Support Vector Machine of Multi-sources' Satellite Images in Lu'an Urban Area
摘要
Abstract
By multi-sources' and multi-temporal satellite images data gathering,the evolution of landscape pattern in 2009-2017 years in Lu'an city was analyzed by using support vector machine classification and GIS technology.The results showed:①The feature interpreting of image object is significant on Sentinel-2 satellite image,also the image resolution to meet the object classes identified standard and the overall classification precision reaches 92.41％.② In the dynamic change of Landscape structure,the water area remained stable,construction area increased by about 3.4 times and the eastward expansion tendency is obvious;the total amount of arable area and forest area decreased year by year in the eastern region and tends to be fragmented;unused areas is affected by the expansion of construction area,which has been in the wave changes.③In landscape evolution,water area maintains the dynamic equilibrium state,construction area and arable area increased respectively by 80.61％ and 55.64％,forest area and unused land reduced significantly by 63.39％ and 72.33 ％ respectively.④In the later stage of evolution,the construction area and arable area has been speeded up obviously,and the evolution rate of arable land began to decline,also the urban expansion is remarkable.关键词
