外文摘要：Subalpine dark coniferous forests in the westera Sichuan Province of China play an important role in the hydrological processes in the upper reaches of the Yangtze River.Second-growth forests,with different stand successional stages,have developed as a result of logging over the past 50 years.Forest cover and stand structure changed greatly with concomitant degradation of forest ecosystem functions.To understand how the stand structures of the second-growth forests change during the stand succession process,we analyzed stand structure characteristics and an old-growth state index of the bamboo and moss-forest types.We found that stand structure at the young successional stage featured one-third of the structure characteristics of the old-growth dark coniferous forests,while the structure of the medium-aged stage had reached half the structure of the old-growth state.The two forest types were similar in the rate of development at the young successional stage but differed at the medium-aged stage;the moss-forest type had more advanced development than the bamboo-forest type at the medium-aged successional stage.
