Forest canopy structure,light environment and their effects on the vegetation pattern and growth of understory in forests
Reviewing the description of the canopy structure and canopy light environment of predecessors,optimize the definition of canopy structure and expounds its ecological significance.Analyze the effect of canopy structure on the light intensity and distribution in the understory layer.Combining the research results of the forest canopy structure and light environment on the forest microclimate characteristics and with the air , soil and other environmental factors of the mutual relationship,summarized the understory vegetation of forest ecosystem for the response of light environment.Tries to summarize the effects of light environment on understory vegetation distribution,the germination of seeds and the growth of seedlings in forest ecosystem,with the aim of providing information for same research.
