中文摘要	【目的】揭示石漠化治理区经果林地土壤养分对间作和单作种植模式的响应机制,为石漠化治理区刺梨、核桃为主的经果林地的植被优化和土壤养分供应提供科学依据。【方法】结合野外采集样本和常规土壤养分分析,运用单因素方差分析、因子分析和排序分析等方法,研究石漠化治理区经果林地土壤养分对种植模式的响应。【结果】除土壤pH随土层加深呈升高外,其余养分含量均随土壤层次的加深呈降低趋势,不同土层土壤以土壤全氮、全磷、速效磷和速效钾含量刺梨-核桃间作高于刺梨单作( P < 0.05), 全钾和碱解氮含量刺梨单作高于刺梨-核桃间作( P < 0.05), 土壤有机质含量在0 ~ 10 cm刺梨-核桃间作高于刺梨单作, > 10 cm后刺梨-核桃间作低于刺梨单作( P < 0.05);刺梨-核桃间作土壤养分供应水平( 0.572分)优于刺梨单作地( 0.439分);全钾、有机质、碱解氮和速效钾是影响研究区土壤养分供应水平差异的主要因子。【结论】石漠化治理区经果林地土壤养分对间作与单作种植模式响应敏感,巩固维持间作地土壤养分含量供应水平,重点补充单作地的土壤养分以提升供应水平。
英文摘要	【Objective】The objective of the paper is to explore the response mechanism of soil nutrients in economic fruit woodland to different intercropping and mono-cropping patterns in rocky desertification control area and to provide the scientific basis for vegetation optimization and soil nutrient supply of economic fruit woodland ( Rosa roxburghii and Juglans regia) in rocky desertification control area.【Method】The response of soil nutrients in economic fruit woodland to cropping patterns in rocky desertification control area was studied by single-factor variance, factor and sort-based analysis combined with field sampling and conventional soil nutrient analysis.【Result】The content of soil nutrients showed a decreasing trend but soil pH increased with increase of soil depth. Total N,total P,available P and available K content in soil with different depth under Rosa roxburghii-Juglans regia intercropping pattern were higher than that under Rosa roxburghii mono-cropping pattern significantly ( P < 0.05) . Total K and available N content of soil with different depth under Rosa roxburghii mono-cropping pattern were higher than that under Rosa roxburghii-Juglans regia intercropping pattern significantly ( P < 0.05) . Organic matter content of soil with 0 - 10 cm depth under Rosa roxburghii-Juglans regia intercropping pattern was higher than that under Rosa roxburghii mono-cropping pattern but organic matter content of soil with > 10 cm depth under Rosa roxburghii-Juglans regia intercropping pattern was lower than that under Rosa roxburghii mono-cropping pattern significantly ( P < 0.05) . The soil nutrient supply level under Rosa roxburghii-Juglans regia intercropping pattern ( 0.572) was higher than under Rosa roxburghii mono-cropping pattern ( 0.439) . Total K,organic matter,available N and available K were main factors influencing soil nutrient supply level in the research area.【Conclusion】The response of soil nutrients in economic fruit woodland to intercropping and monocropping patterns is sensitive in rocky desertification control area. The Rosa roxburghii-Juglans regia intercropping pattern and Rosa roxburghii mono-cropping pattern can consolidate and maintain the supply level of soil nutrient content in intercropping woodland and supplement soil nutrients in mono-cropping woodland for improving its supply level.
