| 中文摘要: |
| 通过调查国家级自然保护区内伶仃岛的土壤肥力和质量状况，掌握其土壤生产力和环境质量
情况，为其生态保护和合理利用提供依据。定点采集土壤剖面样品并进行室内实验分析，测定土壤剖面样
品肥力和重金属含量，并与1997 年数据进行比较，探讨内伶仃岛不同土壤类型的土壤肥力和重金属变化情
况。与1997 年数据相比，内伶仃岛4 种类型土壤肥力无明显变化，土壤pH 均有所下降，重金属含量除铬
外均有不同程度升高，增幅最大的锰达到362.3%，最低的铅为29.38%。调查的4 种土壤类型中，变质岩赤
红壤肥力状况较好，滨海沙土和石质土肥力较差，整体有酸化趋势，重金属含量升高较多但在安全范围内。 |
| 英文摘要: |
| In this study，the soil fertility and quality in the Neilingding Island，a national natural conservation
area，were investigated to provide a basis for its ecological protection and rational utilization. Samples were collected
from soil profiles and analyzed for fertility and total heavy metals，and the results were compared with those of 1997 so
as to know soil fertility and total heavy metal changes of 4 types of soils in Neilingding Island. The results showed that
fertility did not change apparently，soil pH decreasd to some extent，and total heavy metals except total Cr increased
by various degrees，compared with in 1997. For the heavy metals，Mn had the largest increase of 362.3%，while Pb
had the smallest of 29.38%. For the 4 types of soils，metamorphic latosolic red soil showed high fertility，while costal
sandy soil and rocky soil had low fertility. Generally，the soils had acidification，and the total heavy metals increased
considerably，but were still within the safety margin. |
