II paesaggio vegetale del territorio collinare anconetano

Abstract

Plant landscape of the hill territory around Ancona. — The phytosociological study of the vegetation of the arenaceous, peliticous-arenaceous, arenaceous-peliticous and alluvial lands of the hilly Ancona sector, in the eastcentral part of the Italian peninsula on the Adriatic side, permitted the reconstruction of different vegetation series which are distributed in close relationship with the area's lithological formations. The edaphous-xerophilous series of the arenaceous substrata corresponds to the Roso sempervirentis-Queroeto pubescentis sigmetum; the climatophilous series of the peliticous-arenaceous substrata is represented by the Asparago acutifolii-Ostryeto carpinifoliae sigmetum, while the climatophilous series of the Lonicero xylostei-Querceto cerridis sigmetum is found on the arenaceous-peliticous substrata. The flood plain series of the oldest alluvial terraces corresponds to the Rubio peregrinae-Carpineto betuli, while in more recent ones the edaphous-hygrophilous series of the Symphyto bulbosi-Ulmeto minoris sigmetum is represented. By integrating these sigmeta, the geosigmetum of the hilly territory of Ancona is obtained.
