中文摘要	【目的】探明石漠化治理不同恢复模式土壤养分的分布特征,为进一步优化石漠化治理植被配置提供科学依据。【方法】以贵州花江石漠化治理示范区花椒、金银花、混交林、砂仁和撂荒地5种样地的土壤为研究对象,在雨季前、中、后对不同样地土壤0 ~10、10 ~20和20 ~30 cm土层进行为期3年的采样监测,分析不同恢复模式下的土壤养分分布特征。【结果】随着植被的恢复,花椒、金银花、混交林和砂仁样地的土壤容重、田间持水量和毛管孔隙度均值较撂荒地分别降低0.61 %、7.97 %和1.12 %;有机碳、全氮、全磷和全钾均值较撂荒地分别增加53.45 %、45.72 %、80.81 %和1.44 %,碱解氮、速效钾均值较撂荒地分别增加53.36 %和25.80 %。同一样地土壤有机碳及土壤养分含量均表现为雨季中(7月) >雨季后(11月) >雨季前(4月)的变化趋势。不同恢复模式土壤养分含量主要集聚于表层,随着土层深度的加深,养分含量逐渐降低。【结论】不同恢复模式间养分含量存在差异,喀斯特石漠化地区的植被恢复对生态环境均具有改善作用。
英文摘要	【Objective】The aim of this paper was to explore the distribution characteristics of soil nutrients in different recovery modes of rocky desertification control,and to provide scientific basis for further optimizing the vegetation allocation of rocky desertification control.【Method】 Taking soil from five sampling sites as the study object,including Zanthoxylum bungeanum,Lonicera japonica,mixed forests,cardamom and abandoned farmland in Huajiang Rocky Desertification Control Demonstration Area in Guizhou.Soil layers of 0-10,10-20 and 20-30 cm were sampled and monitored for 3 years before,during and after rainy season,and the distribution characteristics of soil nutrients under different recovery modes were analyzed.【Result】With the restoration of vegetation,compared with abandoned farmland,average values of soil bulk density,soil retention ability and capillary porosity in the four plots decreased respectively by 0.61 %,7.97 % and 1.12 %,soil organic carbon,total nitrogen,total phosphorus and total potassium increased by 53.45 %,45.72 %,80.81 % and1.44 % respectively,hydrolyzed nitrogen and available phosphorus increased by 53.36 % and 25.80 %,respectively.In the same plot,the contents of soil organic matter and soil nutrient contents were all shown as during rainy season >after rainy season >before rainy season.With the increase of depth of the soil layer,content of soil nutrients of different recovery models decreased,nutrients mainly concentrated in the surface layer.【Conclusion】There were differences in nutrient contents between different restoration models,and vegetation restoration in karst rocky desertification area had an ameliorative effect on ecological environment.
