摘要 对 35年生福建青冈人工林和杉木人工林生物量及土壤肥力进行调查,以研究福建青冈人工林培肥土壤和涵养水源的功能,结果表明:营造福建青冈人工林后林地土壤水稳性团聚体含量增加,团聚体的稳定性增强,容重降低,总孔隙度增加,林地土壤结构状况、孔隙、水分和养分状况均得到不同程度的改善,福建青冈人工林比杉木林能更好的培肥土壤;福建青冈叶的最大持水率明显高于杉木叶,其林分地上部分最大持水量是杉木林的1.17倍,由于福建青冈林土壤结构及孔隙状况的改善,林地蓄水能力增强,使得该林分表现出比杉木林更好的水源涵养功能. The soil fertility and the water conserving capacity of the 35 - year - old Cyclobalanopsis chungii and Cunninghamia lanceolata plantations were studied by investigating into the biomass and soil fertility of these plantations. The results showed that the Cyclobalanopsis chungii plantation had better function to improve water conserving capacity and soil fertility compared with the Cunninghamia lanceolata plantation. The steadiness of soil aggregate and porosity were promoted, the bulk density was decreased, and the water and nutrient conditions in the Cyclobalanopsis chungii plantation were better than those of in Cunninghamia lanceolata plantation. The water holding rate of Cyclobalanopsis chungii leaves was 1.17 times that of Cunninghamia lanceolata leaves. Conclusively speaking,the function of improving the water conserving capacity and soil fertility of Cyclobalanopsis chungii plantation was better than that of Cunninghamia lanceolata plantation.
