摘要: Land use/cover (LUC) and changes between 1990 2003 in a tropical mountainous watershed were analysed with Landsat TM images using GIS-RS approach. The La Antigua River upper catchment is 1325 km2, biodiverse hydrological region central Veracruz, Mexico. A large set of training pixels was used to optimize the representation environmental heterogeneity. Classification accuracy assessed spectral field-checked error matrices. Overall classification for (78.2%) (79.7%) satisfactory. Ancillary data (DEM) incorporated improve discrimination LUC categories. sensor proved sensitive enough separate different patterns related classes this complex landscape. time interval scale selected are suitable strategic planning purposes. Depletion montane cloud forest, its conversion pasture agriculture, by far most important change over period study.
