Abstract:The nature environment affects plants mainly in the aspect of climate, hydrology, soil and terrain. On large scales, climate type obviously affects the zonal distribution and spatial patterns of plant species. On medium and small scales, soil, hydrology, topography and their interaction usually affect the necessary environment and resource condition for plant growth, and even becoming decisive factors on species diversity in plant community. Multivariate quantitative analysis is an important method in researching ecology relationship of plant community, and plays a key role in revealing the relationship between plant community and environment. As a powerful tool of quantitative analysis, ordination methods often play an important role in studying plant ecology, which become a trend in applying to plant community distribution and community structure. The application of ordination methods was reviewed from the angle of plant community distribution and community structure, the main problems were analyzed, and the development direction in future was proposed, so as to provide references for the choice of ordination methods in the future.
