A weighting-rating method to evalaute soil erosion for land use planning: a case study in Sagunto area (Spain)

摘要

A weighting-rating method to evalaute qualitatively both present and potential soil erosion for land use planning in the Mediterranean Region (Recatala & Sanchez~10) is applied to Sagunto area (Spain) on a scale of 1:25.000. The method takes into account the following factors: rainfall, soil, lithology, vegetation, topography, erosive morphology and soil conservation management. Both present and potential soil erosion of mapping units are classified using a classification reference system with five classes that express soil erosion from very low to veyr high degree. Sagunto is a dynamic coastal area in the east of the Valencian Mediterranean Region, where soil erosion is an issue to be considered bydoing land use planning. Mapping units with hihg or very high present soil erosion repreent 12.30
