中文摘要	为研究喀斯特石漠化地区土壤属性和土壤质量对不同生态修复模式的响应,选取贵州省贞丰县花江石漠化治理示范区为研究区,以耕地、次生林、花椒林土壤为研究对象,分析土壤物理、化学和生物属性对生态修复的响应。基于方差分析、相关分析、敏感性分析和主成分分析筛选土壤质量的关键评价指标,采用土壤质量综合指数法定量评价,评估生态修复对土壤质量的影响。结果表明:生态修复显著影响土壤属性,进而影响土壤质量。土壤质量评价指标最小数据集由土壤团聚体几何平均重量直径、易氧化有机碳、有机碳和细菌数量4个指标组成。平均重量直径和易氧化有机碳的权重最大(0.44),表明其对土壤质量综合指数的贡献最大,是土壤质量的主要限制因子。土壤质量综合指数由高至低为次生林(0.69) >花椒林(0.46) >耕地(0.25),次生林土壤质量综合指数显著大于花椒林,次生林和花椒林土壤质量综合指数显著大于耕地(P<0.05)。两种生态修复措施均显著提高和改善了土壤质量。
英文摘要	In this study,we aimed to assess the responses of soil properties and quality to different ecological restoration models in a karst rocky desertification area.We selected the following two ecological restoration models:the conversion of cultivated land to secondary forest and Zanthoxylum bungeanum forest and the use of cultivated land as a reference,in Huajiang rock desertification demonstration in Zhenfeng County in Guizhou Province.The physical,chemical,and biological properties of soil were measured in surface soil (0-10 cm) to evaluate the responses of soil to the two ecological restoration models.Key soil quality indicators were assessed based on variance,correlation,and sensitivity analyses and principal component analysis.The influences of the different ecological restoration models on soil quality were evaluated using an integrated soil quality index(SQI).The results indicated that ecological restoration had significant effects on soil properties,and thus,soil quality.Four indicators,namely,geometric mean mass diameter(MWD),easily oxidized organic carbon (EOC),organic matter(SOC),and soil bacterial quantity were selected in the minimum data set for the calculation of SQI.Among these indicators,MWD and EOC had the highest weighted values(0.44),indicating that they made the highest contribution to the final SQI,and were accordingly the main factors limiting soil quality.Furthermore,we detected significant differences in the SQIs among the cultivated land,secondary forest,and Z.bungeanum forest(P<0.05),which increased in the order of cultivated land(0.25)
