Different types of vegetation in the riparian zone of the Gil Gonzales river basin were determined using a spectral analysis of ASTER images with spectral indexes and the normalized vegetation index, return light ratio and Tasseled Cap Transformation. In each type of the vegetation, plots measuring 30 * 30 m were installed and the floristic and structural variables and functional traits related to the ability to absorb nutrients and sediment retention were evaluated. Also, a cost-distance model was applied to determine the spatial distribution of the buffering capacity along the riparian area. For this purpose, the average values of the vegetation structure and functional traits were used as friction variables. Five different vegetation types, well differentiated in structure and distribution of functional traits, were determined. The different tree species comprising the riparian vegetation were classified into four functional types of plants: in terms of ability to absorb nutrients: “conservational species “ characterized by low growth rates and low rates of nutrient exchange and “acquisitive species “ characterized by high growth and high rates of nutrient exchange. Due to the condition of sediment retention, species were classified as “interceptive“, characterized by presenting modifications at the trunk base to increase the interception and surface runoff water retention and “non –interceptive”, species lacking or having small changes at the trunk base. It was concluded that the buffering capacity is a function mainly determined by the vegetation width and slope being the vegetation structure as well as the functional diversity additional factors used to define the buffering capacity.
