摘要 新疆是我国沙拐枣属植物分布最多的省份,有19种,约占了82.6%,其中新疆特有种有5个,在北疆准噶尔盆地分布种类最多;从沙拐枣的形态、遗传、物候、抗逆性以及分布格局五个层面进行分析研究,揭示新疆沙拐枣属植物多样性特征以及与生态环境之间的关系,并为深入开展沙拐枣的生态系统结构与功能研究,以及自然植被的科学经营与保护提供科学依据。 Xinjiang is the province in China with the most Calligonum L. There are 19 species ,82.6% which takes of total in China and among them 5 species are endemic species in Xinjiang, which mainly distribute in Junger Basin. The biodiversity characteristics of species, chromosome, phenology, stress resistance and distribution pattern were discussed. The research probed to the relationship between Calligonum L. biodiversity and the environment. These help to study the ecological structure and functions and provide the scientific basis for management and protection of CaUigonum L. in Xinjiang.
