Abstract

This paper reports a phytosociological survey on the perennial halophilous vegetation of the coastal salt marshes in Sicily. Data available from the literature have been supplemented with original relevés performed in different salt marshes in Sicily. A total of 470 relevés according to the standard procedures of the Braun-Blanquet method were processed. For the definition of plant communities and alliances, hierarchical clustering was performed by using Bray-Curtis coefficient and Detrended Correspondence Analysis ordination methods. The Salicornietea fruticosae class is represented in Sicily by two, floristically and ecologically well differentiated, orders: Salicornietalia fruticosae, including seven alliances (Arthrocnemion macrostachyi, Inulion crithmoides, Limoniastrion monopetali, Limonion ferulacei, Salicornion fruticosae, Sarcocornion alpinii, Suaedion verae), and Halocnemetalia cruciati, including only one alliance (Halocnemion cruciati). Within this class, 12 plant associations were recognized, of which a new association (Junco subulati-Limonietum narbonense), included in the Salicornion fruticosae alliance.

摘要

本文报告了一项对西西里岛沿海盐沼常年嗜盐植被的植物社会学调查。从文献中获得的数据已经补充了在西西里岛不同盐沼中进行的原始记录。根据Braun-Blanquet方法的标准程序，总共处理了470个相关内容。为了定义植物群落和联盟，使用Bray-Curtis系数和Detrended对应分析法排序方法进行了层次聚类。所述Salicornietea fruticosae类在西西里由两个来表示，区系和生态分化良好，命令：Salicornietalia fruticosae，包括7个联盟（Arthrocnemion macrostachyi，Inulion crithmoides，柠檬单胞菌（Limoniastrion monopetali），柠檬单胞菌（Limonion ferulacei），Salicornion fruticosae，Sarcocornion alpinii，Suaedion verae）和Ha（Halocnemetalia cruciati），仅包括一个联盟（Halocnemion cruciati）。在该类别中，公认了12个植物协会，其中一个新的协会（Junco subulati-Limonietum narbonense）被包括在Salicornion fruticosae联盟中。
