区域定量划分方法的初步研究——兼论用断裂点理论进行区域划分问题

STUDY ON QUANTITATIVE METHOD OF REGIONAL DIVISION:ALSO ABOUT THE QUESTIONS OF BREAKPOINT THEORY

区域包括均质区域和结节区域 2种形态 .均质区域可用泰森三角形、趋势面、聚类分析等方法进行区划 ;结节区域之间的分界点轨迹从理论上说是一个圆 ,在现实中可以用断裂点模型和图上作业相结合的方法进行区划 .关键是要定义好中心度 ,扣除内部自我服务部分 ,确定好中心地的等级 ,并结合自然界线、交通线路走向等 。

Regions consist of equal region and nub region and equal region can be divided with the methods of Taisen triangle, trend surface, clustering and so on; The track of boundary points of nub regions is a circularity and nub region can be divided with the model of breakpoints combined with exercising on map. The keys are how to define center intensity, affirm the grade of center poles, draw out the hinterland bound uniting with natural borderlines and traffic routes and so on.
