| 摘 要： | 对 18年生湿地松、杉木林取代马尾松林后的土壤肥力状况进行了比较分析。结果表明 ,湿地松林地的土壤水稳性团聚体、非毛管孔隙度、毛管孔隙度、自然含水量、最大持水量、田间持水量及土壤主要养分含量均呈增大趋势 ,土壤结构破坏率和容积质量则呈下降趋势 ;而杉木林则与此相反。由此可见 ,杉木林不利于保持和改善土壤的肥力性状 ,而湿地松林具有良好的改良土壤能力 ,有利于林业的持续发展。

| Abstract: | Through comparatively analysis on soil fertilities following replacement of Pinus massoniana plantation by 18-year-old Pinus elliottii plantation and Cunninghamia lanceolata plantation. The result shows that soil aggregate, non-capillary pore, capillary pore, moisture capacity, maximum moisture capacity and main nutrients of Pinus elliottii plantation increased, whereas the rate of structure fragmentation and volume of soil decreased, but Cunninghamia lanceolata plantation was on the contrary. Therefore, the soil fertilities of Cunninghamia lanceolata plantation became degraded after plantation. But Pinus elliottii plantation had a good ability to modify soil, which is advantageous to the continued development of forestry. |
