中国盐生植物区系研究

Flora study of Halophytes in China

中国盐生植物有 66科 ,2 0 0属 ,42 5种 ,研究首次对其组成成分、区系成分等进行了统计分析 ,认为中国盐生植物区系与热带植物区系有密切的关系 ,与温带植物区系有较密切的关系 ,并与古地中海成分有一定的关系。对植物区系的 5个基本特征分析认为 ,中国盐生植物区系的古老性与复杂性较高 ,而丰富性、成分特有性和种系发育性较低。

China has Halophytes 425 species belonging to 200 genera and 66 families.The paper stats and analyses its components,and floristic elements for the first time.Halophytic flora of China can be thought to have very consanguineous relation with tropical flora,and to have relatively consanguineous relation with temperate flora,and it has definite connection with ancient Mediterranea.The analysis of five fundamental characteristics of halophytic flora of China considers that the floristic acientness and complex of floristic element are relative high,but the floristic abundence,growth of speciation and endemicity of floristic elements are lower.
