| 摘 要： | 新疆甘家湖自然保护区种子植物共有42科137属233种,植物区系组成中最大科是藜科(24属69种),该科也正是新疆盐生植物区系最大的科;本研究区盐生植物有69属99种,占总属及种数的50.4%、42.5%;除世界分布科外,温带分布科和热带至温带分布科占第一位,各均含10种;属的地理成分中以地中海区、西亚至中亚分布型(含变型)占优势, 有45属,占总属数的39.8%;种的区系以温带成分(53.1%)和古地中海成分(42.4%)占绝对优势,中亚分布型(27.0%)、温带亚洲分布型(25.7%)、旧世界温带分布型(21.6%)比重明显大。区系基本特征表现为:优势科现象明显,单种属和少种属占据比率很高;地理成分优势性显著,来源较广泛,有一定古老成分,特有程度极低,具极为明显的盐生性质和温带干旱区荒漠性质;区系中包含国家级和省级重点保护珍稀濒危植物11种和被认为"新疆可能已消失的物种"中的3个种,都具有极其重要的保护价值。

| Abstract: | There are 233 species of seed plants in Ganjiahu Nature Reserve, belonging to 137 genera and 42 families; the largest family Chenopodiaceae (69 species) in this flora is also the largest family in halophytes flora in Xinjiang. There are totally 69 genera and 99 species of halophytes in Ganjiahu Nature Reserve, occupying 50.4% and 64.9% of the total number of genera and species respectively. At family level, besides cosmopolitan family, the temperate type and tropical to temperate type which contains 10 species respectively are the main elements. At genus level, the geographical components are mainly the Mediterranean, W. Asia to C. Asia distribution type and subtypes, containing 45 genera, occupying 39.8% of the total number of genera. At species level, the geographical components are mainly Temperate floristic elements (53.1%) and Old Mediterranean floristic elements (42.4%). C. Asia distribution type (27.0%), Temperate Asia distribution type(25.7%) and Old World Temperate distribution type(21.6%) are important in this flora. The basic characteristics of the flora are as follows: Dominant family is prominent in the nature reserve; The genera with single species and few species occupied high percentage of the total number; The flora is various in floristic elements; There are some ancient floristic elements; Endemic characteristics of species are not obvious; The flora is of typical halophyte and typical temperate arid desert characteristics; 11 rare and endangered species of national or provincial level and 3 species which are regarded as probably disappeared species from Xinjiang are found in the nature reserve, all of these species have important protective values. |
