【摘要】：地理對象之間的關(guān)聯(lián)關(guān)系是地理對象之間的相互作用形式。任何地理對象都不是獨(dú)立存在的,與其他的地理對象有一定的關(guān)聯(lián)關(guān)系,并且這些關(guān)聯(lián)關(guān)系是復(fù)雜多樣的。地理場景就是在地理對象之間普遍存在的、復(fù)雜多樣的關(guān)聯(lián)作用下形成的一個(gè)統(tǒng)一的整體。傳統(tǒng)GIS數(shù)據(jù)模型對地理對象之間關(guān)聯(lián)關(guān)系的描述多側(cè)重于空間關(guān)系,其他的關(guān)聯(lián)關(guān)系往往需要經(jīng)過比較復(fù)雜的計(jì)算和推理后求得,難以完整地表達(dá)地理對象之間復(fù)雜的相互作用關(guān)系,不完全符合人類對地理現(xiàn)象的認(rèn)知情況。然而,在全空間系統(tǒng)中,可以根據(jù)常見的地理分析需求對多粒度時(shí)空對象間關(guān)聯(lián)、作用關(guān)系進(jìn)行分類表達(dá),便于客觀實(shí)體全方位的抽象與表達(dá)。對象間的關(guān)聯(lián)關(guān)系可主要分為空間關(guān)系、時(shí)間關(guān)系、屬性關(guān)系、因果關(guān)系、認(rèn)知關(guān)系5大類。本文用地理實(shí)體作為案例,分析了關(guān)聯(lián)關(guān)系的表達(dá)模型。
[Abstract]:The relationship between geographical objects is a form of interaction between geographical objects. Any geographical object does not exist independently and has a certain relationship with other geographical objects. And these relationships are complex and diverse. Geographical scenes are common among geographic objects. The traditional GIS data model focuses on spatial relationships in describing the relationships between geographical objects. Other relational relationships often need to be obtained by more complicated calculation and reasoning. It is difficult to express the complex interaction relationship between geographical objects in a complete way, which does not fully accord with human cognition of geographical phenomena. In the whole space system, the multi-granularity spatio-temporal objects can be classified and expressed according to the common needs of geographical analysis. The relations between objects can be divided into five categories: spatial relation, temporal relation, attribute relation, causality relationship and cognitive relationship. The expression model of correlation relation is analyzed.
