我国东部山地植物物种多样性垂直格局的比较研究

China is a mountainous country and has a wide geographical range from the tropical to subarctic and from lower land area to the highest peak (Everest) of the world. A number of mountains concentrate not only biological and geographical characteristics of horizontal zones, but also have rich natural habitats and vegetation types due to less impact of human activities. Therefore, these areas are becoming refuges for many endemic species and have a high biological diversity. For these reasons, the mountainous area is providing an appreciated field for exploring and testing some biodiversity hypotheses. .Using integrated methods of tree plot survey, geostatistics, multi-statistics, and GIS-based DEM (Digitizal Elevent Model), this project aims at exploring patterns and their regional difference of species diversity along altitudinal gradients, and at analyzing their possible mechanism and effects on structures and functions of plant communities in mountainous regions of eastern China. .In the past three years, the same experimental designs and mthods have been used for conducting tree plot survey for each mountain. A total of about 600 tree plots with a size of 600-1000 m2 have been carried out across eastern China. By now, some of data have been analyzed and published in some journals, and most of them are in progress. .
