罗布泊野骆驼自然保护区植物组成及区系特征研究

Study on Plant Composition and Floristic Characteristics of the Wild Camel Nature Reserve in LOP Wild Camel Nature Reserve

依据2010年4月至2011年12月多学科综合考察的结果,罗布泊野骆驼国家级自然保护区范围内共有种子植物28科76属130种,属于典型的荒漠植物区系;区内种子植物属的区系成分较为多样,其中北温带分布型比例最大,占总属的27.6%,其次为地中海区、西亚至中亚分布型占较大比重,优势种由古老成分组成,仅含1属的分布型共有5个(中国特有分布、东亚分布、热带亚洲(印度—马来西亚)、旧世界热带分布、东亚和北美间断分布)。保护区植物组成及区系特征也说明了保护区所处的特殊的自然地理位置、气候环境特点对该区植物地理分布的决定性影响。

According to the results of the multi - disciplinary comprehensive inspection fromthere are 28 families, 76 genera and 130 species of seed plants in the wild camel National Nature Reservebelong to typical desert flora. Seed plants of the genus flora composition varies, the type, accounting for 27. 6% of the total genera,followed by the Mediterranean region,west Asia and central Asia represents asignificant proportion of distribution type , dominant species by ancient composition , distribution of type of a total of five. The plant composition and floristic characteristics of the reserve also show that the special natural geo-graphical position and climatic environment characteristics of the reserve have a decisive influence on the geographical distribu-tion of plants in the area.
