| 中文摘要: |
| 对广东省龙门县南昆山省级自然保护区亚热带山地常绿阔叶林土壤分层取样并进行理化性质研究。结果表明：土壤理化性质随土层深度变化而变化，大部分理化指标具有极显著相关性；土壤物理性状总体良好，绝大部分土壤容重处于中等水平，土壤孔隙数量比较理想，毛管与非毛管孔隙比比较合理，土壤通气、保水能力比较协调；土壤有机质和有效氮含量较高，有效磷、有效钾和交换性盐基含量均较低。 |
| 英文摘要: |
| The soil of subtropical montane evergreen broad-leaved forest in Nankunshan Provincial Nature Reserve, Longmen County, Guangdong Province was sampled to study physical and chemical properties. The results showed that the physical and chemical properties of soil changed with the depth of soil layer, and most physical and chemical indexes had very significant correlation; the soil physical properties were generally good, most of the soil bulk density was at the medium level, the number of soil porosity was ideal, the ratio of soil capillary porosity and air-filled porosity was reasonable, and the soil ventilation and water holding capacity were coordinated; the contents of soil organic matter and available nitrogen were high,but the contents of available phosphorus, available potassium and exchangeable base were low. |
