5Forest recovery after clear-cutting in Chinese pine(Pinus tabuliformis) plantations of North China显示文摘In Hebei Province of North China, forest was recovered with natural recruitment in plantations with large area of clear-cutting Chinese pine(Pinus tabuliformis). This study was aimed to demonstrate the dynamic characteristics of recruits during the natural recruitment. Both plot survey and the spatial point-pattern analysis were performed. Five developmental stages of natural recruitment were selected and studied, including 1 year before and 2, 5, 8, and 11 years after clear-cutting. Different slope aspects were also included. Natural recruitment was always dominated by Chinese pine with a proportion of higher than 90%. For plots of 1 year before clear-cutting on east-and north-facing slopes, recruit densities were 7886 and 5036 stems/hm2, the average heights were 0.78(±0.85) and 1.06(±1.15) m, and the average diameters at breast height(DBH) were 3.21(±1.38) and 2.91(±1.38) cm, respectively. After clear-cutting, recruit density was initially increased, then it was gradually declined with time; however, the variation of average DBH was contrary to that of recruit density. Both of them were no longer varied between 8 and 11 years after clear-cutting. The average height of recruits continued to increase after clear-cutting. For the plots of 11 years after clear-cutting on east-and north-facing slopes, average heights of recruits reached 2.00(±1.14) and 2.24(±1.20) m, respectively. The statuses of recruits on north-facing slopes were better than those on east-facing slopes after clear-cutting. Meanwhile, recruits on east-facing slopes were always aggregated at small scales, while spatial pattern of recruits varied with time on north-facing slopes. Moreover, forest was recovered more quickly by natural recruitment than by artificial afforestation after clear-cutting. The structural diversity was higher in naturally regenerated forests than in plantations of the same age. Our results demonstrated that clear-cutting of Chinese pine plantations recovered by natural recruitment has the potential to be an effective approach for establishing multifunctional forest.DONG Boqian ZHAO Kuangji WANG Zhibin JIA Zhongkui MA Lvyi XIA Xinli 2018Journal of Arid Land2018,10,2:1

7Effect of Forest Management Measures on Soil Respiration and Its Mechanism显示文摘Global warming is one of the hottest environment problems.One of the reasons is the sharp increase of CO2 in atmosphere.Soil respiration in forest ecosystems accounts to 60%-90%of total ecosystem respiration and is therefore one of the key components of the global C cycle.This paper summarized different responses of soil respiration to forest management measures,and described the relevant researches at home and abroad on the effect of management measures like harvesting,forest fertilization,soil improving(Liming),litter removal, and prescribed burning on soil respiration.Wang Xiyang Ma Lvyi Jia Zhongkui Liu Jie You Weibin Zhang Tiantian 2012Chinese Forestry Science and Technology2012,11,3:0
