This paper analyzes Yunnan’s tourism revenues between 2001 and 2012 adopting such indexes as St and Vt,its tourist flow,and the spatio-temporal trail of and reasons for its tourism income’s focus employing gravity model and regional barycenter model.The findings suggest that the focus of tourists’flow between 2001 and 2012 shifted along the line “southwest-northwest-southeast-northwest”,that the focus of tourism revenues changed westwards along the line “west-northwest-southwest-west”, that there are vast differences of tourism development between cities,that focus changed little within an area,and that the tourism center moved west-wards and northwards with rising regional discrepancies.Corresponding strategies to promote Yunnan’s spatial and temporal tourism growth are also proposed.%文章以云南省为研究对象，选取标准差（St）和变异系数（Vt）对2001—2012年云南省旅游收入变化差异进行分析，借鉴物理学重力模型，并运用区域重心模型研究方法对云南省旅游客流量和旅游收入重心的时空动态变化轨迹与成因进行详细分析，结果表明：（1）2001—2012年云南省旅游客流重心呈“西南—西北—东南—西北”移动趋势，旅游收入重心呈“西—西北—西南—西”移动趋势，整体向西移动；（2）省内市州之间旅游业发展的总体差异较大，区域内发展不平衡明显；（3）重心变动区域范围较小，旅游重心整体偏西偏北移动，非均衡发展态势明显。由此提出了云南省区域旅游发展时空方面的相应对策。
