三峡库区特有植物疏花水柏枝的调查研究

INVESTIGATION AND STUDY ON THE ENDEMIC PLANT MYRICARIA LAXIFLORA IN THE THREE-GORGE RESERVOIR AREA

疏花水柏枝（Myricarialaxiflora）是三峡大坝建成后唯一1种将全部被淹没的库区特有植物物种。在实地系统调查的基础上，阐述了疏花水柏枝的形态特征、分布现状、生长环境和群落结构等特点；从生物学、生态学角度分析了它在长江沿岸消涨带内汛期被洪水淹没的生长特性。

Myricaria laxifolia, one of the plant species endemic to the Three-Gorge reservoir area,is the only one species that will submerged completely after the ThreeGorge dam built. Based on the results of a field study in the area, the morphological character, nature distribution region, habitat, plant community structure of the species are reported;its biological and ecological adaptability to the environment submerged during the period of flood is also analyzed in this paper,so as to provide a scientific basis for the ex situ conservation of the species.
