Research usejP.Haggett"s pattern of spatial structure and system, analysis technique of tourism market space and data of spot check to analyze the evolvement of spatial structure and problems of tourism development from six faces, move, path, crunode, significance of crunode, ground and diffuse. The law of the evolvement of spatial structure: First, tourism development keeps rising. Second, AR of xi"an is very big and stable, Xi"an is tourism hotspot and center. Third, origin market space sticks out east, and isn"t continuous. Fourth, tourist proportion of XAZ follows the low of distance decay. Distance decay is very obvious in adjacent zone because of little attraction. Sixth, the spatial distribution of tourist origins has become less concentrated. Tourist origins of east China develop quickly. Three problems: First, tourism development is very unbalance between Xian and its adjacent zone.

西安及毗邻地区的国内客源市场空间结构的研究，采用了英国著名地理学家哈格特描述的空间结构模式与秩序，利用旅游市场空间分析技术，借助市场抽样调查、数量分析，从运动模式、路径、结点、结点层次、地面和扩散6个层方面进行了剖析，归纳总结出5个客源市场空间结构演变规律：(1)旅游业发展整体保持增长趋势；(2)客源吸引半径大而稳定，西安市是全国性的旅游热点城市和旅游中心城市；(3)客源市场分布突向东部，呈不连续分布；(4)游客比重的距离衰减普遍存在，毗邻地区吸引物及自然吸引物吸引力较小，距离率减明显；(5)客源集中度减小，客源市场发展呈现跳跃式增长的演变规律。3个市场拓展面临的问题：(1)西安与毗邻地区间旅游业发展不平衡现象明显；(2)客源市场区位不佳；(3)旅游产品单一老化，类型单调乏味。
