摘　　要：木荷、杉木混交林林地与根际土壤养分特征研究表明,木荷根际对土壤养分的活化能力大于杉木,这利于混交林中杉木的生长。木荷与杉木混交后两树种种间关系协调,混交林根际微区对土壤养分活化程度的提高改善了两种树的养分利用状况,这可能是混交林林地土壤养分高于其纯林地土壤养分且林分生产力高的主要原因之一。为探讨木荷、杉木混交林效益机理提供科学依据。Investigations were run on the nutrients of the land soil and the rhizosphere soil in the mixed forest of Cunninghamia lanceolata （ Lamb. ） Hook and Schirna superba Gardn. er Chcvmp. Results indicated that the nutrient content of the forestry soil could be significantly varied by the dif- ferent mixture afforestation methods for these tree species.
