根据时间、空间和物质运动的不可分离性,构造了不同时态物质“存在”的定义;引入同位点集和异位点集后,推导了静态和动态地物的数学模型;论述了动态地物的量变和质变形式;论证了制图区域动态特点和演化的逻辑必然性。
According to the inseparability relationship among time,space and motion of matter,the definition of matter existance is given in different tenses.After introducing the concepts from the same place points set and different place points set,the mathematical model of static and dynamic geo-object is inducted.The quantitative and qualitative change forms of dynamic geo-object are discussed.The logic certainty of dynamic feature and evolution in cartographic area is demonstrated.
