中文摘要	以苏尼特右旗短花针茅荒漠草原为对象,运用L_(16)(4~5)正交试验设计,采用直观分析、最优母序列关联和全信息模型研究短花针茅荒漠草原植物群落多样性对施肥的响应。结果表明,短花针茅荒漠草原群落多样性对肥料的响应程度:尿素>磷酸二铵>有机肥;最优处理组合为施尿素225kg/hm~2(A4)、磷酸二铵112.5kg/hm~2(B2)、有机肥15000kg/hm~2(C3),即A4B2C3组合;潜在的最优处理组合为施尿素150kg/hm~2(A3)、磷酸二铵225kg/hm~2(B3)、有机肥15000kg/hm~2(C3),即A3B3C3处理组合;施肥能够明显增加群落的alpha多样性。
英文摘要	The research focused on response of the community diversity of Stipa breviflora in desert steppe to fertilization, the experiment was conducted with Stipa breviflora in Sunite county, Inner Mongolia. L_(16)(4~5) orthogonal experimental design was used to analyze the sampled data by visual analysis, the optimal sequence correlation and the full information model. The results showed that degree of the response of community diversity to fertilizer was nitrogen fertilizer>phosphatic fertilizer>organic fertilizer, the optimal treatment was applying the nitrogen fertilizer(A) 225kg/hm~2,phosphatic fertilizer(B) 112.5kg/hm~2,orga-nic fertilizer(C) 15000kg/hm~2,that was the combination A4B2C3, the potential optimal treatment was applying the nitrogen fertilizer(A) 150kg/hm~2,phosphatic fertilizer(B) 225kg/hm~2,organic fertilizer(C) 15000kg/hm~2, that was the combination A3B3C3.Fertilization can significantly increase the alpha diversity of community.
