| 摘 要： | 通过对乐昌含笑和杉木人工林生物量和土壤肥力的调查,进行乐昌含笑人工林培肥土壤和涵养水源功能的研究,结果表明:营造乐昌含笑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、孔隙和养分状况得到不同程度的改善,乐昌含笑人工林具有比杉木林更好的培肥土壤功能;乐昌含笑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1.14倍,同时由于乐昌含笑林土壤结构及孔隙状况的改善,林地蓄水能力增强,使得乐昌含笑人工林表现出比杉木林更好的水源涵养功能。

| Abstract: | The biomass,soil fertility and water holding capacity were investigated in the Michelia chapensis and Chinese fir plantations.The result showed Michelia chapensis plantation had good function to improve water holding capacity and soil fertility compared with the Chinese fir plantation.The soil aggregate composition,porosity,water and nutrient condition in the Michelia chapensis plantation were better than that in Chinese fir one.The water holding rate of Michelia chapensis leaves was higher than that of Chinese fir,and its water holding capacity was 1.14 times of Chinese fir one.Therefore,the function to improve water holding capacity and soil fertility by Michelia chapensis plantation were better than that of Chinese fir one. |
