          Abstract

          RESUMO O presente trabalho teve como objetivo caracterizar a flora e as fitocomunidades de um gradiente de restinga da planície litorânea Estado de Santa Catarina, correlacionando-as com os atributos edáficos. Para o levantamento florístico foi utilizado o wide patrolling, enquanto a estrutura da comunidade foi determinada pelo método de parcelas. Amostras de solo de cada fisionomia foram coletadas para análise de macronutrientes, matéria orgânica, umidade e espessura da serapilheira. A flora é composta por 319 espécies, dentre as quais 244 ocorrem de forma exclusiva nas formações de restinga herbácea (63), restinga arbustiva (32), restinga arbustivo-arbórea (46) e floresta de transição (103). O padrão estrutural de cada fisionomia da restinga estudada foi influenciado por fatores edáficos, como os teores de matéria orgânica, potássio, alumínio, a capacidade de troca catiônica e espessura da serapilheira, sendo estes atributos determinantes da flora característica de cada fitocomunidade.

          ABSTRACT The present work characterized the flora and phytocommunities of a restinga gradient on the coast plain of Santa Catarina State and correlated them to edaphic attributes. The floristic survey followed the wide patrolling method and the community structure was determined through the plot method. Soil samples of each physiognomy were collected for analysis of macronutrients, organic matter, moisture, and litter thickness. Flora comprises 319 species, 244 of which occur exclusively in formations of herbaceous restinga (63), shrub restinga (32), shrub-tree restinga (46), and transition forest (103). The structural pattern of each restinga physiognomy studied was influenced by edaphic factors as organic matter, potassium, and aluminum contents, cation exchange capacity, and litter thickness. These attributes are determinant for the flora characterizing each phytocommunity.
