Taking national tourism areas above A level in Xia men as the research object，this paper studies geographic concentration degree, equilibrium degree and connectivity of tourism areas by using the geographical mathematics method. The result shows that the spatial distance of class A tourist attraction in Xia men is evenly distributed on the whole; the connectivity in the tourist attractions is low，there is still room for further improvement； Under the premise of exploring the main factors which influence the spatial structure of the tourist attractions in Xia men，some strategies to integrate and optimize the spatial structure of Xia men scenic areas are proposed．
