| 中文摘要: |
| 为探明台湾牛樟人工林对引种区土壤化学性质的影响，研究在海南北部引种2 年的台湾牛樟
人工林、木棉- 台湾牛樟混交林，以及添加天然有机质椰糠后土壤化学性质的变化。结果表明：以当地土壤
（砖红壤）营造台湾牛樟人工林，0～20、20～40 cm 表层土壤的pH 值较造林前下降了0.3 个单位，主要土
壤营养成分含量整体上增加，引种区土壤肥力提高；与台湾牛樟人工林相比，木棉- 台湾牛樟混交林表层
土壤速效钾、铵态氮和硝态氮含量分别提高了45.10%、15.84% 和45.00%，土壤有机质、全氮、全钾、全磷、
效磷含量降低，pH 值与造林前相同；以1∶1 比例混合红壤和椰糠基质营造台湾牛樟人工林，土壤pH 值为
3.97～3.99，表层土壤速效钾、硝态氮、铵态氮显著高于对照（砖红壤），其他土壤主要营养成分含量低于
对照。综上所述，营造台湾牛樟人工林可以提高引种区的土壤肥力，而与其他林分混交或添加有机质对增
加引种区林地土壤肥力的效果较小。 |

| In order to prove the effect of Cinnamomum kanehirae Hayata forest plantation on soil chemical
properties of introducing area，the changes of soil chemical properties of C. kanehirae Hayata forest plantation，
bombax–C. kanehirae Hayata forest plantation and after adding natural organic matter coconut bran in red soil for 2
years in the north Hainan province were studied. The results indicated that the topsoil pH value of 0-20 cm and 20-40
cm reduced by 0.3 units and the main nutrient content of topsoil increased in C. kanehirae Hayata forest plantation，
which compared with before the afforestation，and it improved soil fertility. Compared with C. kanehirae Hayata forest
plantation，the contents of soil available potassium，ammonium nitrogen and nitrate nitrogen improved by 45.10%，
15.84% and above 45.0%，respectively，but the contents of soil organic matter，total nitrogen，total phosphorus，
available phosphorus and potassiumdecreased in bombax—C. kanehirae Hayata forest plantation. The soil pH value
of bombax—C. kanehirae Hayata forest plantation was the same with before the afforestation. When mixed red soil and coconut bran were used to cultivate C. kanehirae Hayata forest，the soil pH value was 3.97-3.99，the soil rapid
potassium，nitrate and ammonium nitrogen were significantly higher than those in the control group（ red soil），and
the quality scores of other major soil nutrients were lower than those in the control group. In summary，planting C.
kanehirae Hayata forests can improve soil fertility of introducing area，but it is less effective to mix with other forest or
add organic matter for improving the soil fertility of introducing area. |
