| 英文摘要: | The Asian monsoon system is a major feature of the Earths climate and impacts on almost half of the population of the world. The monsoon also has a profound effect on the regions flora, fauna and ecosystems. Moreover large parts of China are also noted for their exceptionally high biodiversity. We also know that the monsoon system has changed over geological time and this is intimately linked to the growth of Tibet and the Himalayas which occurred during the Paleogene (66 to 23 million years ago) and early Neogene (23 million years ago to 3 million years ago). And finally we know that this time interval also witnessed the birth of this modern vegetation patterns. So how are all of these aspects linked together. Why is biodiversity so high in parts of China? When did these ecosystems develop? And how is this all connected to Tibetan uplift and the evolution of the monsoon?
Our project aims to bring together a unique group of world leading researchers in palaecology, geology and climate modelling to identify the nature of ecological change during the Paleogene and early Neogene and establish the underlying mechanism of changes and thresholds.
We will do this with a series of three field trips to span the latitudinal and elevation gradients within China, from Tibet, Yunnan and S. China. These field trips will enable us to collect new information on the changes in ecosystem and biodiversity. We will be able to assess the amount of change, and in a few key sites identify whether the changes have been smooth or relatively abrupt, the latter indicating possible threshold behaviours of the system. We will also use this data to reconstruct estimates of the climate and palaeoelevation of the sites. This information can then be used to help develop and test climate, ecosystem, and biodiversity models. These models will allow us to identify the key mechanisms that have driven change in this region over geological time, and the interactions between the ecosystem and climate change.
The outcomes will be a fuller understanding of the evolution of life on the planet, and will also enable a unique evaluation of the models used for future climate change projections. |
