| 摘 要： | 在对徐州石灰岩山地不同植被恢复类型土壤理化性质研究的基础上,综合分析了不同植被恢复类型对土壤健康影响,结果表明：石灰岩山地不同植被恢复模式土壤健康存在明显差异。其中：针阔混交林中土壤物理性质较好,说明混交林在一定程度上改善了土壤物理性质;土壤有机质和各养分含量上层明显高于下层,且各养分含量均以针阔混交林最高,进一步说明混交林在一定程度上改善了土壤化学性质。应用主成分分析方法对3种植被类型林分土壤健康状况综合评价指标主成分得分,针叶林为-8.309,针阔混交林为6.876,阔叶林为1.433。各类型林分土壤健康状况排序为：针阔混交林〉阔叶林〉针叶林,表明针阔混交林能够改善土壤健康状况。建议在徐州石灰岩山地上应以针阔混交林为主要恢复模式,从而提高该地区土壤的健康水平。

| Abstract: | Based on the investigation of the of soil physical and chemical characteristics of different forest restoration communities in limestone mountain in Xuzhou,a comprehensive evaluation was made about influence of different forest restoration communities on the soil health.The results showed that there existed significant differences in soil health among of three types of vegetation restoration in Limestone mountain.The soil physical properties in mixed forests was better among all vegetation types,which indicated that mixed forests were improved.The soil organic matter and nutrient in upper soil layer was better than that in the lower layer,and the soil organic matter and nutrient was the highest among all vegetation types.This may further be explained that mixed forests could improve the soil chemical properties.Soil health of three vegetation types was evaluated by principal component analysis.The forest soil health index of coniferous forest was-8.309,mixed forest was 6.876,broadleaf forest was 1.433.This indicated that mixed wood could improve the soil health level.We suggested that restoration of mixed wood model should be enlarged in order to improve soil health condition in this area. |
