The spermatophyte flora consists of 1520 species in 686 genera and 161 families. The western coastal flora is explicitly of tropics in nature.The statistics of distributional patterns of taxa shows that genera and species of tropical distribution take up more than 93% and 80% of the total taxa of the flora respectively .There are about 250 plant communities, 118 of which are monodominant .The communities are characterized by co-edificatoes more than monodominant species in the comunities, distribution on a small scale for the most of plant communities, thorny fruticeta, shrublands, herbages. and azonation. On the western coast there are abundant in resource plant species, poor in storage quantity, there are still some plants for promising development and utilization.
