研究青藏高原不同退化程度高寒草地生态系统陆表能量、水分循环特征和变化规律，分析并为后续的参数化方案确定典型下垫面上的陆表（土壤）动力学和热力学特征参数。

英文摘要

The characteristics of land-surface energy, water circulation and change law of the alpine grassland ecosystem with different degrees of degradation in qinghai-tibet plateau were studied, and the dynamic and thermodynamic characteristics parameters of the land-surface (soil) on the typical underlying surface were analyzed and determined for the subsequent parameterization scheme.
