Résumé

With the covering herbaceus species data of 425 sample plots from 0.25 m2, representative of harvest grassland at Riaño (León), a structural analysis is carried out, taking account the diversity and their components. The high number of samples allows a detailed statistical analysis of frecuency distribution for richness, covering, equitability and diversity. Because the enviromental features of the área, a sectorial study is carried out regarging two different senses of stratification: the hydrografic basin and geomorphology. In both cases the heterogeneity valúes between samples are defined, and also the variability between both, basin and geomorphologic levéis is evaluated.
