Abstract: Based on the systematic investigation of arthropods in cotton agroecosystem,the dominant index of numbers and energy flow values in arthropod pest,predator and parasite sub-communities were analyzed in this papers.The different orders of dominant species were occurred on the dominant index of numbers and energy flow values.Furthermore,it is better to reflect the dominant species of agroecosystem by the evaluation of energy flow values than by numbers.

Key words: Castanopsis carlesii forest, fine-root biomass, morphological plasticity, specific root length, tree species diversity.
