人工林地力衰退研究现状与进展

介绍了国内外人工林地力衰退的历史背景和现状，从人工林群落结构、土壤微生物种群区系、土壤理化性质和生化特性，栽培措施等方面分析了导致人工林地力衰退的原因，提出了调整林分结构，保护林下植被、混交，林地施肥和土壤改良、科学营林等措施防止地力衰退；概述了人工林地力衰退的研究进展和今后研究方向。

Research Status and Advances of Land Degradation of Artificial Forests

Under the historical background and current situation at home and abroad,cause of land degradation of artificial forests were revealed by analysing communal structure,soil microflora,soil phychemical and biochemical charater,cultivation methods.Corresponding countermeasures were put forward such as regulating stands structure,protecting undervegetation,mixed stands,fertilizing,and soil improvement,scientific management.The research advances and direction were summarized.
