新疆博格达峰南缘濒危地衣物种多样性及分布格局

博格达峰是天山东段著名的高峰。博格达峰南缘较干旱，因此、壳状地衣资源丰富，是我国重要的地衣物种基因库，也是我国地衣物种多样性研究的重要区域之一。本研究基于新疆地衣研究现状，参照我国其他省区和国际地衣学的研究内容，采用形态解剖、化学方法、生态类型及地理成分分析等传统分类方法外与现代分子系统学研究方法相结合，对该地区地衣物种多样性进行分类研究，搞清楚该地区地衣种类分布概况。该地区南缘的铁，煤，石灰石等矿产开发日益扩大面积，给地衣物种的分布带来威胁，部分地衣种类生存在濒危状态下。本研究在野外采集濒危地衣标本，在室内从传统的分类方法及现代分子方法进行物种鉴定，分析它们生态地理特征。在研究结果的基础上建立地衣种类标本库，建立新种和中国新记录种基因库。最终建立该地区地衣物种标本库。将我们的研究成果让国内外同行专家共享。这对正在编写的“中国地衣志”的顺利完成，即将要编写的新疆孢子植物志迈出重要的一步。

Bogda is the famous peak in the eastern area of Tianshan Mountain. Because of the dry climate of the southern margin of Bogda, abundant crustose lichen resources distributed in this area will be an important gene base for lichen species researches and the area will be one of the main regions for the study of lichen species diversities in our country. Based on the present situation of research on lichens in Xinjiang and other provinces as well as the international studies of lichens, to study the species diversity and distribution character of lichens in this region by using morphological anatomy, chemical method, ecological type and geographical component analysis etc, combined all these traditional classification methods with modern methods of molecular systematics are the main purpose of the present research. Nowadays, the expanding of the exploration and exploitation of mineral products, iron, coal, limestone etc in this region become one of the main threat to the distribution of lichen species , survival of some lichen species in this area are seriously endangered. For this reason, endangered lichen specimens collected from this area will be classified in the lab by traditional method combined with modern molecular techniques and the eco- geographical characteristics of them will be analyzed in our project. Based on the results of the research, the data base of endangered lichen species and gene bank of the new species and new to China records will be established. Finally, herbarium of endangered lichen specimen in the southern margin of Bogda in Xinjiang will be constructed. The results of the study will be shared with experts both at home and abroad and it will provide precious references for the successful completion of “Lichen Flora of China” as well as the compiling of “Spore Flora of China”.
