本文应用模糊分析方法研究了中国竹亚科特有属植物区系地理成分;12个特有属归为华夏(占总属数的16.67％)、西南(占41.67％)、华南(占33.33％)和华东(占8.33％)四种成分;所含72个种划分为西南(占总种数的40.28％)、华南(占33.33％)、华东(占15.28％)和华中(占9.72％)四种成分。其结果再次证实了“西南至华南尤其西南地区是中国竹亚科特有属甚至竹亚科及其区系的起源地带”一观点。此外,本方法获得的结果还能以定量的形式准确地表达各植物区系地理成分之间的亲缘关系及其程度。
In this paper, we use the fuzzy analysis method to study the geographical components of the endemic genera of bamboo subfamily in China. The 12 endemic genera are classified as Huaxia (16.67% of the total), southwestern (41.67%), southern (33.33%) and East China accounted for 8.33%, and 72 species were divided into Southwest China accounting for 40.28%, South China accounting for 33.33%, East China accounting for 15.28% and Central China accounting for 9.72% ingredient. The results again confirmed the “Southwest to South China, especially the southwestern China is a subfamily of bamboo subfamily and even bamboo subfamily and its fauna origins” point of view. In addition, the results obtained by this method can also accurately and quantitatively express the genetic relationship between the geographical components of each plant and its extent.
