| 摘 要： | 通过对上海辰山植物园辰山山体残存半自然森林群落土壤理化因子的测定,结合凋落物和岩石裸露等相关分析,探讨城市化地区孤岛状山体残存植被土壤特征。结果表明,辰山山体残存半自然植被的土壤容重、密度、毛管孔隙度多低于人工植被土壤,土壤呈弱酸性,与上海普遍的中性偏碱森林土壤明显不同,残存半自然植被土壤有机质含量与总氮、总磷等养分含量较高。辰山孤岛状山体土壤理化性质不仅与残存植被协同变化,也与群落凋落物显著相关,且与地形和人为干扰有关。

| Abstract: | This paper discussed the soil properties of the remnant forest vegetation on isolated hills located in built area of Shanghai by testing the soil physical and chemical factors of the remnant semi-natural forest vegetation in Shanghai Chenshan Botanical Garden and analyzing the litterfall and rock exposure. The results showed that bulk density, density and capillary porosity capacity of soil in semi-natural vegetation communities was lower than those of artificial vegetation soil. And the soil there is weak acidic, which differs from the neutral and alkaline soils of most forest in Shanghai, and also contains higher organic matter content, total N and total P. In Chenshan, which is an isolated island-like hill, the soil physical and chemical properties have changed synchronously with the natural process of the vegetation communities, and are significantly correlated with the litterfall, terrain and human disturbance respectively. |
