Abstract: Studies on plant population ecology have greatly expanded in China during the past decade. Most of the studies were focused on the traditional population demography, life history patterns, genetic diversities, adaptations and population dynamic modeling. The most outstanding trait in the studying progress of plant population ecology in past ten years was to cross and mergence with other relevant biological disciplines, as well as to apply the theories and study methods of the other disciplines in plant population researches. In addition, there has been a trend in transforming the study of population demography into testing population changes mechanisms in plant population studies.
