摘要：为了开展神农架国家公园土地覆盖动态演变过程研究,揭示土地覆盖时空变化规律为神农架国家公园的环境保护、生态文明建设提供理论基础。利用1990-2016年的遥感影像数据,采用监督分类的最大似然分类器对影像进行分类,从土地覆盖类型变化和土地覆盖时空变化两方面分析神农架国家公园土地覆盖变化检测。结果表明：（1）神农架国家公园近30年来土地覆盖类型以植被为主,植被面积一直处于增长趋势,占土地覆盖总面积的比重逐年增加,由1990年的80.58%增长到2016年的94.20%;（2）近30年神农架国家公园植被面积不断增加,非植被面积不断减少且动态度依次增大,土地覆盖变化缓慢,但植被覆盖面积呈上升趋势,植被增加重心主要集中在中部,植被减少重心比较分散。
In order to study the dynamic evolution of Shennongjia National Park land cover, the spatio-temporal change of land cover was analyzed to provide the theoretical basis for the environmental protection and ecological civilization construction of Shennongjia National Park. The maximum likelihood classifier was used to classify images based on the remote sensing image data from 1990 to 2016. Shennongiia National Park land cover change detection was analyzed in terms of land cover type and the temporal and spatial variation of land cover. The results show that（1）The main types of land cover has been vegetation in Shennongjia National Park in recent 30 years, vegetation area has been increasing, and the proportion of total land cover area has increased year by year, from 80.58% in 1990 to 94.20% in 2016; （2）The vegetation area increased continuously in Shennongjia National Park in recent 30 years, and the non-vegetation area decreased and the dynamic degree increased successively. The land cover change of Shennongjia National Park has been slow, but the vegetation coverage area is on the rise, the center of gravity of vegetation increase is mainly in the middle, while the vegetation reduction is dispersed.
