中文摘要：

以淮海经济区为研究对象,运用旅游经济联系强度模型、隶属度模型及断裂点模型,定量测度该区域城市间的旅游经济联系强度、隶属度及城市旅游控制范围.结果表明：在旅游经济联系强度上,该区域城市间差异显著,鲁南旅游经济联系较强、皖北旅游经济联系较弱,东北部远超西南部;在旅游经济联系方向上,主要方向表现出旅游中心城市和相邻城市指向特征;在旅游经济联系范围上,旅游中心城市相互之间的断裂点数值较大,旅游辐射范围较广,而对皖北地区的断裂点值普遍不高;根据断裂点并结合隶属度将区域分为徐州、济宁、亳州、淮安和连云港这五大旅游经济圈,并在整体上形成＂一核四辐射＂的空间格局.

英文摘要：

By taking Huaihai economic zone as the research object, the approaches of the gravity model of tourism economic linkage intensity, the subjection degree, as well as the theory of breaking point are used to quantitatively measure the degree of tourism economic linkage intensity, membership and the range of cities tourism control, the result shows that on the degree of tourism economic linkage, there are great differences in this area in tourism economic linkage intensity, southern Shandong is stron-ger and northern Anhui is weaker, present northeast is far more than southwest; on the linkage direction, it shows that the spatial interaction between every two cities is characterized by the obvious tourism cities pointing and adjacent cities pointing; on the range of tourism economy linkage, tourist center cities between them have higher score of breaking point and wider periphery of tourism, but the breaking point score is generally not high in northern Anhui ; according to the calculated data, we divide Huaihai economic zone into five small tourism economic circles, they are Xuzhou, Jining,Bozhou,Huaian, Lianyungang, forming space structure called “a core and four radiations” as a whole.
