中文摘要：

由于区域背景和旅游区域合作的共生环境,青藏地区旅游在本质上存在一种共生关系.本文引入种群生态学中的共生理论,选取具有代表性的青海和西藏作为基本共生单元,通过对青藏地区的1999-2009年入境旅游数据的整理,运用EXCEL对Theil系数、游客转移态等定量评价.结果表明：从空间尺度上,青藏地区空间转移态整体呈上升趋势;在时间尺度上,Theil系数总体差异演变呈波动发展,趋势呈下降状;青藏地区入境旅游流的共生态势趋同,存在较强的共生关系.

英文摘要：

Because of regional background and tourist regional symbiotic environment, there exists a kind of symbiotic relationship of Qinghai Tibet Area in essence. This paper introduces the theory of symbiosis of Genecology, select the typical Qinghai and Tibet as basic symbiotic unit,By the analysing of the data of inbound tourism from the year 1999 to 2009 and study the Transfer state, Theil coefficient in the method of EXCEL,the study finds： From the spatial scale, Transfer state of the Qinghai-Tibet area overall upward trend in state： In the time scale, Theil coefficient of the overall downward trend, trend of convergence of the Qinghai-Tibet area＇s inbound tourism flow symbiotic, the two units have a tight correlation and a strong symbiotic relationship.
