| 摘 要： | 应用Shannon-wiener生态位宽度与Petraitis特定重叠指数数理模型,对临洮县东山造林站植物种群生态位特征进行分析,结果表明,在人工修复干扰因素下,植物种群生态位宽度值差异较大,介于10.4569～0.1633.以Shannon-wiener生态位宽度可将植物种群分成4个类群,种群的生态位宽度越宽,与其它...

| Abstract: | The Shannon-wiener niche breadth width and Petraitis niche overlaps index was used to analysis niche characteristics of plant population of Dongshan afforestation.The results showed that there is great difference among the difference of niche breadth of plant population,during 10.4569~0.1633,the plant population has been divided for four types during artificial interference factors.With broad niche breadth,the niche of other populations had a higher rate of overlaps and the niche overlap of the populations ... |
