Abstract

To fully understand the dynamics of land use change it is necessary investigate the net change, exchanges and transitions occurring between land use categories. Therefore, this research explores the spatial and temporal trends of changes in land use, vegetation and water bodies in the state of Nayarit from 1993 to 2014. To do so, the INEGI vegetation maps (series II and IV) for both dates were validated with field observation, resampled and overlaid using TerrSet environment in order to calculate the change matrix, and from it estimate the losses, gains, net changes, total changes and exchanges between land use categories. Results indicate that of the 2,783,572.50 hectares of the total area, 58.06% remained without any change and 41.94% experienced some change. Within such area, 15.42% were exchanges between land categories whereas 26.52% were net change. Agriculture is the category that gained most area; occupying 18.17% of the total in 1993 and 22.14% in 2014. Oppositely low forest has decreased from 20.82% to 13.76% during the same period.

1993-2014年墨西哥纳亚里特州土地利用、植被和水体变化的空间分析

为了充分了解土地利用变化的动态，有必要调查土地利用类别之间发生的净变化、交换和转换。因此，本研究探讨了1993年至2014年纳亚里特州土地利用、植被和水体变化的时空趋势。为此，通过实地观测验证了两个日期的INEGI植被图（系列II和IV），并使用TerrSet环境重新采样和叠加，以计算变化矩阵，并据此估计土地利用类别之间的损失、收益、净变化、总变化和交换。结果表明，在总面积的2783572.50公顷中，58.06%没有任何变化，41.94%经历了一些变化。在这一区域内，15.42%是土地类别之间的交换，而26.52%是净变化。农业是获得最多面积的类别；1993年占18.17%，2014年占22.14%。同期，相对较低的森林从20.82%下降到13.76%。
