中文摘要	世界各地生态环境的优劣与区域大地热流的高低有密切关系。一般认为生态系统的能量来源于太阳辐射。但是，太阳辐射的昼夜反差很大，季节变化明显，区域生态系统必须承受这种能源供应的显著波动，其生物的多样性将受到限制，区域生态系统必然变得比较脆弱，对人类活动影响的承受能力非常有限。大地热流比值较高的地区，大地热流也成为驱动区域生态体系发育演化的重要能源。这种能源比较稳定，对生物发育的限制要少得多，其生物多样性比较丰富，区域生态系统比较稳健，对人类活动的影响有较大的承受能力。研究大地热流对西部生态环境退化的影响和机理，将为西部地区的环境、生态建设及管理决策提供科学依据。
英文摘要	The quality of the ecological environment all over the world is closely related with the density of the terrestrial heat flow in the region. It was generally believed that "the energy of the ecological system comes from solar radiation", but the solar radiation changes sharply between day and night and from season to season, hence the ecological system in the region will become fragile and easy to be affected by human activity for the restriction of the biologic diversity due to the significant fluctuation of the energy supply. Terrestrial heat flow may become an important energy source for the development and evolution of the ecological system in the region with high terrestrial heat flow, where the ecological system will become robust and is able to sustain stronger interference by Human activity for the development of the rich biologic diversity resulted from stable energy supply. Study on the mechanism and influence of the terrestrial heat flow on the degradation of the ecological environment in the western China will provide scientific basis for making decision in the management and construction of the ecological system and environment in the region.
