摘      要：We present stationarity criteria for forest stands,and establish embodiments using a Norwegian empirical stand development *** natural stationary states only slightly differ from the outcome of long-term simulations previously implemented using the same empirical *** interference in terms of diameter-limit cutting is ***,stationary states differing from the natural one *** volume,growth and monetary value appear low but the financial return rate may be *** yield and financial return clearly contradict each other,the former arising from harvesting large trees,the latter from frequent removal of small *** exponential tree size distribution does not appear to comply with the stationarity criterion.
