Integrated System Analysis to Understand the Implications of the Asian Monsoon System on the Tibetan Hydrology with Focus on Nam Co Basin

青藏高原对亚洲季风系统的影响对全球气候动态具有突出的相关性，而亚洲季风系统反过来又对脆弱的西藏生态系统造成反馈。考虑到全球气候变化，人们对季风动态对生态水文系统的影响知之甚少，但冰川和永久冻土融化以及蒸散速率增加的证据表明，在水资源供应方面，系统发生了重大变化。这项研究的主要目的是开发一种综合系统分析方法，以便了解亚洲季风系统对纳木错盆地的水文影响，将湖平面波动与其支流的水平衡模型联系起来。综合实地研究、地质统计学、遥感和地理信息系统技术将利用J2000模型提供分布式、面向过程的水文模型所需的时空数据、参数和信息。这将导致对气候变化影响的季风动力学对西藏盆地水平衡的影响进行预测性评估。

The Tibetan Plateau has an outstanding relevance for the global climate dynamics through its impact on the Asian monsoon system, which in turn causes feedbacks to the vulnerable Tibetan ecosystem. Considering global climate change, little knowledge is given on the impact of the monsoon dynamics on the eco-hydrological system, but evidence of melting glaciers and permafrost as well as increasing evapotranspiration rates indicate significant system changes regarding water availability. The main objective of this research study is the development of an integrated system analysis approach in order to understand the hydrological implications of the Asian monsoon system on the Nam Co Basin, linking lake level fluctuations with water balance modelling of its tributaries. Integrated field studies, geostatistics, remote sensing and GIS techniques will provide the spatio-temporal data, parameter and information required for distributed, process-oriented hydrological modelling, utilizing the J2000 model. This will result in a prognostic assessment of the impact of climate change affected monsoon dynamics on the water balance of Tibetan basins.
