摘　　要：福建柏木荷混交林林地与根际土壤养分特性研究表明，木荷根际对土壤养分的活化能力大于福建柏，这利于混交林中福建柏的生长。木荷与福建柏混交两树种种间关系比较协调，混交林根际微区对土壤养分活化程度的提高改善了两树种的养分利用状况，这可能是混交林林地土壤养分高于纯林地且林分生产力高的主要原因之一。The rhizospere soil and wood soil in 10a old of Fokienia hodginsii with Schima superba mixed forest was determined. The result indicates that rhizospere of Schima superba activation ability to soil nutrition is stronger than Fothenia hodginsii's. This make for growth of Fokienia hodginsii in mixed forest. This type of mixed forests has the advantages of coordinate interspecific relation. The advance of activation ability to soil nutrition of the rhizospere tiny-area of mixed forests improve forest nutrition utilized. This is one possible primary reason that soil nutrition and productivity in mixed forest are higher than pure forest.
