传统的GIS主体功能区划分存在等级分界处评分差别太大、不能区分同级别不同类别、主观赋权引起的评价结果受主观影响较大等不利因素，已有的文献未能将相关的数学模型引入GIS进行改进，导致主体功能区划分结果精度较低。因此引入系统聚类法进行县域尺度主体功能区划分，采取变异系数法确定权重，以胶州市为例进行了实证分析，将胶州市分为四类区域：都市核心圈、核心外围圈、限制发展圈、禁止发展区；并依据主体功能区划分结果和城市总体规划的原则，将胶州市规划为“一核一轴两翼五区”的发展模式，从而将主体功能区与城市总体规划有机地衔接在一起。研究结果与胶州市实际情况相符，本研究对于其他县域主体功能区划分和城市总体规划具有一定的实践意义。
傳統的GIS主體功能區劃分存在等級分界處評分差彆太大、不能區分同級彆不同類彆、主觀賦權引起的評價結果受主觀影響較大等不利因素，已有的文獻未能將相關的數學模型引入GIS進行改進，導緻主體功能區劃分結果精度較低。因此引入繫統聚類法進行縣域呎度主體功能區劃分，採取變異繫數法確定權重，以膠州市為例進行瞭實證分析，將膠州市分為四類區域：都市覈心圈、覈心外圍圈、限製髮展圈、禁止髮展區；併依據主體功能區劃分結果和城市總體規劃的原則，將膠州市規劃為“一覈一軸兩翼五區”的髮展模式，從而將主體功能區與城市總體規劃有機地銜接在一起。研究結果與膠州市實際情況相符，本研究對于其他縣域主體功能區劃分和城市總體規劃具有一定的實踐意義。

There exist unfavorable factors in traditional GIS major functional areas. The related mathematical models in existing literature are not introduced to GIS, which leads to a lower accuracy of the results of major functional areas zoning. So system clustering is introduced as the way of county scale main functional areas zoning. The variation coefifcient method is taken to determine the weight of indexes, and Jiaozhou city is taken as an empirical example. Jiaozhou city is divided into four types of regions:the urban inner circle, core peripheral circle, restricted development circles, and the Prohibited development area. According to the main functional areas divided results and the overall urban planning principles, Jiaozhou city is planned as"one core, one axis, two wings and ifve areas"development mode, so the main functional areas with the overall urban planning are organically combined. The results match the actual things, so the research has a certain practical signiifcance of major functional areas zoning for other country planning.
