摘要：[目的]本研究旨在评价滇东南喀斯特区不同植被恢复措施的土壤质量,以期为石漠化治理和植被生态恢复提供依据。[方法]以云南省建水县不同植被恢复措施为研究对象,基于聚类分析及主成分分析法建立最小数据集,利用全量及最小数据集土壤质量指数进行土壤质量评价。[结果]显示:(1)不同植被恢复措施的土壤理化性质差异显著(p<0.05),随土层深度增加而降低(土壤密度除外);车桑子灌木林有机碳、速效钾含量显著高于其他恢复措施;云南松针叶林总孔隙度及速效钾含量低于其他恢复措施。(2)基于主成分分析法的最小数据集适合作为喀斯特区最小数据集提取方法;最小数据集由有机碳、全氮、氨态氮、总孔隙度、非毛管孔隙度、全镁组成。(3)5种恢复措施土壤质量排序为:马尾松针叶林>车桑子灌木林>天然次生林>直杆蓝桉阔叶林>云南松针叶林。[结论]喀斯特区进行人工林恢复时可优先选择马尾松针叶林进行种植。
[Objective]To evaluate the soil quality of different vegetation restoration measures in karst region of southeast Yunnan for providing basics for the control of rocky desertification and ecological restoration of vegetation.[Method]In this paper,different vegetation restoration measures in Jianshui County of Yunnan Province were carried out.The minimum data sets were established by cluster analysis and principal component analysis.The soil quality indexes of the full and minimum data set were used to evaluate soil quality.[Result]The results showed that:(1)There were significant differences in soil physical and chemical properties among different vegetation restoration measures(P<0.05),which decreased with the increase of soil depth.The contents of organic carbon and available potassium in Dodonaea viscosa forest were significantly higher than those through other restoration measures.The total porosity and available potassium content of Pinus yunnanensis Franch.pure forest were lower than those through other restoration measures.(2)Quality evaluation of the minimum dataset using principal component analysis was suitable for the extraction of karst area.The minimum data set consisted of organic carbon,total nitrogen,ammonium nitrogen,total porosity,non-capillary porosity and total magnesium.(3)The soil quality of the five restoration measures was ranked as:Pinus massoniana pure forest>Dodonaea viscosa shrub forest>Natural secondary forests>Eucalyptus maideni pure forest>Pinus yunnanensis pure forest.[Conclusion]Pinus massoniana Lamb.are preferred species for plantation restoration in karst areas.
