监测生态交错带等自然地区土地覆盖的变化已成为森林管理的重要工具，特别是在保护区。本研究利用遥感技术、地理信息系统（GIS）和景观生态学定量指数，分析了蒙卡约自然公园（西班牙）1987年至2010年森林覆盖的时空变化。这两年使用四张陆地卫星图像绘制了该保护区的九个代表性土地覆盖类别。 1987年和2010年土地覆盖图总体分类精度分别为87.65%和84.56%。在景观层面获得的景观指标显示破碎化程度的增加，从而导致景观空间多样性的增加。着眼于类别层面，结果显示无柄橡树（Quercus petraea）和山毛榉林（Fagus sylvatica）的森林扩张，这是这个自然公园的两个重要的生物气候指标，因为它们是这些物种在欧洲最南端的位置。主要引进松林的减少和混合灌木地区向天然林地区的转变解释了上述破碎化的增加。这些结果与评估期间森林管理者设计的自然保护策略一致。
Monitoring the change in land cover in natural places, such as ecotones, has become an important tool for forest management, especially in protected areas. The present work analyses the spatial and temporal changes in forest cover in Moncayo Natural Park (Spain) from 1987 to 2010 using remote sensing techniques, geographical information systems (GIS) and quantitative indices of landscape ecology. Four Landsat images were used to map nine representative land cover categories in this preserved area in both years. The overall classification accuracies in land cover cartographies in 1987 and 2010 were 87.65% and 84.56%, respectively. Landscape metrics obtained at the landscape level show an increase in fragmentation and, as a result, an increase in landscape spatial diversity. Focusing on the class level, the results show a forest expansion of sessile oaks (Quercus petraea) and beech forest (Fagus sylvatica), two important bioclimatic indicators in this natural park, because they are the southernmost locations for these species in Europe. The decrease of mainly introduced pine forest and the transformation of mixed shrub areas into natural forested areas explain the aforementioned increase in fragmentation. These results are in agreement with the strategies for nature conservation designed by forest managers during the period evaluated.
