Research Of Habitat Limitations Of Plant Diversity In Qinling Mountains

In recent years,due to global climate change and the interference generated by human production and living activities,global biodiversity is gradually declining.Research on the conservation of biological diversity has been a focus of our immediate concern and an urgent problem to be solved.The Qinling area is a good place for the study of species diversity in China.There are a wealth of Chinese endemic species among numerous plant species.Based on the field survey,literature review and data analysis,the paper comprehensively analyzes the establishment of the limited habitat list of the habitats in the Qinling Mountains,analysis of plant type diversity,flora characteristics,plant level and vertical distribution patterns,and the current status of plant life.The main results are as follows:1.Habitat limitations of plant in Qinling mountains there are 100 families,338 genus and 721 species of plant,the habitat limitations of Qinling mountain of five types of narrow distribution range of up to 420 kinds of species and distribution of the north side there are 191 species,the distribution of the southern side there are 58 species,indicator plant species only eight,and other special habitat of plant has 102 species.2.Floristic characteristics:Plant species are abundant,dominant families and genuses are distinct;life style diversity is dominated by herbaceous plants;geographic components are numerous,mainly temperate,geographically connected,and endemic species abundant.3.In the horizontal distribution pattern of the habitat limitations of plant in Qinling mountains,the western and southern parts of the Qinling Mountains are rich in habitat types,but are less distributed in the east and north.The life forms of the species are complex and varied,from west to east and from the south to the north are decreased;the geographical component of the genus is of a temperate nature.4.In the vertical distribution pattern,the number ofthe habitat limitations of plant in Qinling mountains increases first and then decreases with the elevation.4.There are only 5 most endangered species,24 endangered species,63 easy to endangered species,40 vulnerable species and 589 safety species.It is suggested to take protective measures: adopt local protection policies,adjust the operation measures,restore forest vegetation,increase propaganda and protection,and actively carry out international exchanges and cooperation.
