Abstract: In terms of the research of long-term site productivity in the world and the status of management and researches of bamboo forests in China,the current status of long-term site productivity,impacting factors and its research strategies were reviewed and discussed.Meanwhile,the research periodic term and frame were put forward.The chronosequence,retrospective and long-term study were introduced for solving the“long-term” problem in the research frame.In the evaluation and prediction of the impact of management practices on long-term productivity,the methodology on site classification and evaluation,expert system and computer simulation models were mentioned,so as to achieve re-adjusting the long-term site productivity by changing the current management practices.As for the maintaining the long-term site productivity,it was proposed that the research of effective microbes should be emphasized for producing the man-made effective microbes in future.It was also suggested that the sustainable ecosystem management techniques should be studied for reducing the risk of the damage on the biodiversity and stability of managed bamboo forests,so as to establish the theory and practical techniques of ecosystem management of bamboo forests.
