摘要：为了防治连栽杉木人工林地力衰退，本文重点论述通过间伐，增大林内透光度，降低林分郁闭度，发育林下植被，改良土壤理、化性质和提高生物活性。研究结果表明：在郁闭度０．７以下的林分中，林下植被发育迅速，间伐４～５ａ后，每公顷生物量可达到４～５ｔ，有效地提高了土壤中营养元素含量，增加了土壤中三大类微生物数量，并使微生物类群也发生了明显的变化，有效地维护和恢复了土壤功能。
In order to prevent and remedy soil degredation of Chinese fir plantation, This paper discusses the following issues: increasing stand light intensity, decreasing canopy closure, developing undergrowth, ameliorating soil properties and enhance soil biological activity through thinning. Research results show that while canopy closure is less than 0 7, undergrowth vegetation can grow fast. Biomass have 4～5 t per hectare after thinning 4～5 years. It is obvious to enhance nutrient contents and amount of three kind of microoganism in soil. Undergrowth vegetation make genus of microorganism vary, enhance soil biological activity , maintain, and resume soil function obviously.
