对宁夏云雾山草原自然保护区植物种群分布格局的分形计盒维数进行了研究。结果表明:本氏针茅、铁杆蒿和百里香是该区的优势种。3种优势种的计盒维数在1.7左右,表明它们具有较大的空间占据能力。但是它们的计盒维数最大值出现的时间不同,本氏针茅、百里香计盒维数最大值出现在封育20a的样地中,铁杆蒿出现在封育25a的样地中。 The fractal properties of the spatial distribution pattern of different populations in Yunwushan Nature Reserve were reflected through the box dimensions. The result shows that Stipa bungeana Trin., Artemisia sacrorum Ledeb., and Thymus mongolicus Ronn. are dominant species of this area. The box dimensions of these species are around 1.7, and these dominant species occupied large ecological space in the area. But they didn t get their highest box dimensions at the same time, Stipa bungeana Trin. and Thymus ... |
