Spermatophyte Diversity in Phoenix Mountain Nature Reserve of Liaoning Province

By routine survey and sampling survey,the diversity,flora and life form of spermatophyte in the Phoenix Mountain nature reserve of Liaoning province were analyzed.The results show that: there are 978 species of spermatophyte which belong to 434 genera and 96 families;in the floristic geographical elements,temperate elements are dominant and tropical elements are plentiful,featuring more in plant crossing but less in endemic species distribution;in Raunkiaer's life-form,there are 294 species of Hemicryphtphytes(30.06% of the total),ranking the first;in Drude'S life-form,perennial herb and annual herb enjoy the dominant place with 721 species(73.72% of the tata1);in ecological types,there are 776 Mesophytes(79.35% of the tota1),but only 10 Hydrophytes(1.02% of the tota1).By economic purposes,the vascular plants in this area can be divided into 9 types.It can be concluded that the seed plants in the Phoenix Mountain are rich in diversity.
