摘　　要：Nitrogen cycling in forest ecosystems has been one of the focuses widely concerned by ecologists in the past decades. Well understanding the pattern of N cycling and N availability in different forest ecosystems all around the world will be of theoretically and practically great significance for studying and resolving the problems of global climate change and biodiversity loss.This paper reviewed the biological and non-biological factors affecting soil N availability in forest ecosystems,and briefly discussed the problems in studying N availability.Nitrogen cycling in forest ecosystems has been one of the focuses widely concerned by ecologists in the past decades.
