镜泊湖世界地质公园位于我国长白山生物多样性保护关键地区—黑龙江省东南部宁安市境内(128°30′~129°10′ E, 43°46′~44°18′ N)，是长白山山脉张广才岭与老爷岭的过渡区。园区4个火山口繁育着罕见的地下森林，由于地处偏远和保护区的保护，植被具有原始性、完整性和独特性，此特殊生境孕育大量中国特有植物和珍稀濒危保护植物，项目组前期踏查发现园区苔藓植物资源丰富，是重要的物种基因库和揭示物种多样性不可多得的理想天然基地。本项目拟对火山生态系统地下原始森林苔藓植物开展物种多样性系统研究，主要内容是野外群落调查、凭证标本采集、物种经典分类学鉴定和构建苔藓植物标本馆，能有效避免曾未发现的苔藓资源绝迹，进而融合植物区系地理学和数量生态学理论方法以量化评估苔藓物种多样性特点，有益于掌握我国苔藓的进化地理起源，为完善亚洲和我国苔藓物种多样性提供重要信息，具有重要的理论、生态、科研三重价值。

Jingpo Lake World Geopark is located in Ning'an, southeast of Heilongjiang province (128°30′~129°10′ E, 43°46′~44°18′ N), which is the key area for biodiversity conservation in China. It is the transitional zone between Ridge Zhangguangcai of Mount Changbai and Ridge Laoye. Four volcanic craters fostered rare underground forests which vegetation was virgin, well-preserved, and unique because of being remote and protected by natural reserve. Special habitat breed lots of endemic, rare and endangered plants. Members of this project team found that the geopark was rich in bryophytes resources, where was an important species gene pool and provided exceptional ideal natural base to reveal species diversity. Systematic study on bryophytes species diversity of underground forest in volcanic ecosystems will be carried out. Main contents of the project are field investigation on bryophytes communities, collection of specimens, identification of species and construction of herbarium, and all the research work will prevent undiscovered resources from being extinct effectively. And thenfloristic geography and quantitative ecology theoretical methods will be integrated to evaluate species diversity characteristics of bryophytes quantitatively. Results of the project will do favor to illuminate evolutionary geographical origin of bryophytes in China. Moreover, it will provide important information for improving species diversity of bryophytes in Asia and China. In short, this project has a theoretical, ecological and scientific triple value.
