%X The maintaining mechanism of species diversity of land plant communities is a key and advancing edge in biodiversity study.Botanists and ecologists have presented many hypotheses and theories with controversies,and no general theory system was available.In this paper,the problem was reviewed mainly on two scales.The first was big spatial scale,aiming at the physical and natural factors that affect the species diversity,including histories and ages of plant communities,gradient changes such as latitude gradient,water gradient,altitude gradient and soil nutrients gradient,area effect,and isolation; and the second was concentrated on a special plant community,and mainly discussed the relationships of biodiversity with biotic factors (primary productivity,relationship between species,and gap dynamics) and abiotic factors (succession,disturbance and spatial heterogeneity,and human activity).
