摘  要：
【目的】研究醉马草与原生种(伊犁绢蒿、新疆针茅)、补播种(红豆草、紫花苜蓿、无芒雀麦)的种间关联,阐明其制约性,明确原生群落的优势种如何被取代、补播牧草能否定居成功。【方法】实地调查草地群落特征,采用Intertype’s K函数对种对进行种间关联分析。【结果】原生区内醉马草与伊犁绢蒿无关联,与新疆针茅在小尺度下成负关联,但各种对植物之间均是随着尺度的增加逐渐由趋向负关联转变为趋向正关联;补播区内醉马草与3种补播种的空间关联均表现为无关联,但具有一定的差异性,醉马草对红豆草、紫花苜蓿的制约能力随着尺度的增加而降低,而无芒雀麦与其相反。【结论】综合种间关联性和群落特征,新疆针茅制约醉马草蔓延的能力强于伊犁绢蒿,这是阴坡新疆针茅群落退化程度小于阳坡伊犁绢蒿的原因之一,而补播区内红豆草和无芒雀麦均对恢复退化草地有一定效果,为该类草地补播种。

摘  要：
【Objective】To learn Achnatherum inebrians and native species( Seriphidium transiliense,Stipa sareptana),cultivar species( Onobrychis viciaefolia,Medicago sativa,Bromus inermis) of species association,and to clarify its conditionality. To make clear how the dominant species of native communities were replaced and whether the planting of grass can settle down successfully.【Method】Based on the investigation of the characteristics of the grassland community,Intertype's K function was used to analyze spatial association between different species-pairs.【Result】A. inebrians and S. transiliense in native area showed no association,and negative correlations in small scale with S. sareptana,but with the increasing of the scale,all kinds of plants were gradually changed from the negative to the positive correlation. The spatial correlation of A. inebrians and the three replanted plants in the sowing area showed no association,but with some differences. The restriction ability of A. inebrians to O. viciaefolia,and M. sativa with decreased with the increase of the scale,but to B. inermis,the function was just the opposite.【Conclusion】Colligating interspecific association and community characteristics,the control ability of S. sareptana to A. inebrians spread ability is stronger than that of S. transiliense. This is because in the shady slope,S. sareptana community degradation is less than that of the sunny slope of S. transiliense,and in the replanting area,replanting M. sativa and B. inermis has certain effect to restore the degraded grassland,which is recommended to supply seeds to the grassland.
