摘　　要：论述我国中亚热带杉木盛产区，通过间伐发育林下植被，改良土壤理、化性质，提高森林土壤生物活性，从而为通过合理的森林经营、发育林下植物群落，维护和提高森林土壤肥力，改良杉木人工林地力衰退，提供可靠的科学数据和途径。This paper deals with that developing undergrowth vegetation can improve soil physical and chemical properties, and enhance biological activities of forest soil in the subtrpical forest region where Chinese fir grows very well.Therefore, the scientific data and ways are provided for maintaining and enhancing soil fertility and improving soil decline of Chinese fir plantation by rational forest management.

关 键 词：林下植被 地力衰退 杉木 人工林
