摘要
比萨森林是一个地中海生态系统，其特点是植物多样性高。为了评估该森林的植物区系多样性，2013年至2017年在该地区进行了133次植物区系读数。共鉴定出54科125属151种，其中菊科、豆科和豆科优势明显。在生物学上，该生态系统以植生植物为主(37%)。在地貌上以显生植物类型为主，而在地理上则以地中海型为主(50%)。Shannon-Winner指数表明，该地区生物多样性相对较低(1.3 bit / ind)，少数物种优势明显。最后，该森林相对受干扰(42%)，受到强烈的人类活动影响。
Analysis of the floristic diversity in a southern Mediterranean ecosystem. Case of Bissa forest, Chlef (Algeria)
The forest of Bissa is a Mediterranean ecosystem, characterized by a high floristic diversity. In order to assess the floristic diversity in this forest, 133 floristic readings were conducted in this area between 2013 and 2017. As a result, it was possible to identify 151 species, 125 genus and 54 botanical families, with a clear dominance of Asteraceae, Fabaceae and Poaceae. Biologically, this ecosystem was mainly dominated by therophytes (37%). Physiognomically, the phanerophytes were the most dominant types, whereas in term of phytogeography this forest was dominated by the Mediterranean type (50%). According to Shannon-Winner index, this area was characterized by a relatively low diversity (1.3 bit / ind), with a clear dominance of a few species. Finally this forest was relatively disturbed (42%) and under a strong anthropozoic influence.
