| 摘 要： | 通过对28年生香叶树和杉木人工林生物量和土壤肥力的测定,进行香叶树和杉木人工林培肥土壤和涵养水源功能的比较研究,结果表明:与杉木人工林相比,营造香叶树人工林后林地土壤水稳性团聚体含量增加,团聚体稳定性增强,土壤密度降低,总孔隙度增加,林地土壤结构状况、孔隙和水分状况得到不同程度的改善,表层土壤养分得到富集,香叶树具有比杉木林更好的培肥土壤功能;香叶树叶的最大持水率高于杉木叶,其林分地上部分持水量是杉木纯林的1.21倍,同时由于香叶树人工林土壤结构及孔隙状况的改善,林地的蓄水能力增强,使得香叶树人工林表现出比杉木林更好的涵养水源功能.

| Abstract: | The water holding capacity and soil fertility of Lindera communis and Cunninghamia lanceolata plantations were analyzed through the biomass investigation and soil measurement.The result indicates that the twenty eight year-old Lindera communis plantation had good function to improve water holding capacity and soil fertility compared to the Cunninghamia lanceolata plantation.The soil aggregate composition,porosity,water and nutrient condition in the Lindera communis plantation were better than those in the Cunninghamia lanceolata plantation.The water holding rate of leaf of Lindera communis was higher than that of Chinese fir,and its water holding capacities was 1.21 times of Cunninghamia lanceolata plantation.Therefore,the function to improve water holding capacity and soil fertility of Lindera communis plantation were better than those of Cunninghamia lanceolata plantation. |
