Abstract: Concepts,theories (including the maximum growth rate theory,the minimum resource requirement theory and two phase resources hypothesis),attributes (asymmetry and environment relation) influencing factors of plant competition,and the relationship between competition and community composition,structure and dynamics were summarized.The focus of controversy were introduced,i.e.,the relative importance of competition to individual growth,reproduction,death and community succession.Three hypotheses were reviewed:Grime considered that competition was not important.Newman & Tilman considered that competition was important.Deborah & Ariel regarded that the importance of competition depended on two conditions:1)How much extent of soil resources decrease is depended on plant absorbing and other factors (such as evaporation and leakage,etc);2) How close is the relationship between livability in interpulse period and decrease of plant growth in resources pulse period.
