| 摘要: |
| 利用样带与样方结合法进行野外调查，测定土壤主要理化指标，基于SPSS 24.0进行皮尔逊（Pearson）相关性分析、单因素方差(One-way ANOVA)分析和最小显著差数法（LSD）多重比较，对小钦岛土壤理化性质的统计学特征及其影响因子进行研究.小钦岛土壤砾石比和含水量平均值分别为20.04％、7.35%；铵态氮、速效钾、速效磷、有机质含量平均值分别为23.67 、212.77、16.15 mg/kg、28.34 g/kg，分别属于五级、一级、三级和三级水平，大部分属于三级土壤；有机质与含水量、铵态氮、速效磷均呈显著正相关.土壤理化性质主要受植被和坡向影响.通过丰富、加深对庙岛群岛的研究，旨在为海岛的生态保护及开发提供参考. |

| Abstract: |
| The main physical and chemical indicators of soil were measured in field investigation combineo with the belt transect and sample methods. Pearson correlation analysis, one-way ANOVA analysis and least significant difference (LSD) multiple comparison based on SPSS 24.0 were used to study the statistical characteristics of soil physical measured and chemical properties and influencing factors on Xiaoqin Island. The average soil gravel ratio and water content are 20.04% and 7.35%, respectively. The average values of ammonium nitrogen, available potassium, available phosphorus and organic matter are 23.67, 212.77, 16.15mg/kg and 28.34 g/kg, respectively, which is cdassified as the fifth, first, third and third grade, respectively. However, most of soil belongs to the third grade. Organic matter correlated positively in high significants with water content, ammonium nitrogen and available phosphorus. The physical and chemical properties of soil are mainly affected by vegetation and aspect. This profound study on one of Miaodao Islands is aimed to provide knowlege for the ecological protection and development of the island. |
