1引言
1.1背景
當(dāng)前人類社會(huì)正邁向信息時(shí)代,而一個(gè)國家、地區(qū)信息化的程度和水平已經(jīng)成為衡量其社會(huì)、經(jīng)濟(jì)發(fā)展綜合實(shí)力和文明發(fā)達(dá)程度的重要標(biāo)志。1998年1月31日,美國前副總統(tǒng)戈?duì)柺状翁岢隽恕皵?shù)字地球”的概念,引起全世界政界和科技界的高度重視,世界各國紛紛制訂計(jì)劃,力圖搶占信息的制高點(diǎn)。于是在全世界范圍內(nèi)掀起了一股數(shù)字化的浪潮,“數(shù)字中國”、“數(shù)字省區(qū)”、“數(shù)字城市”等計(jì)劃相應(yīng)提出。
數(shù)字城市的概念有廣義和狹義之分。廣義上的數(shù)字城市即指城市信息化,又可以叫做信息城市(informationcity)、信息港(information port)或稱智能城市(intelligencecity)。具體是指通過建設(shè)空間基礎(chǔ)信息平臺(tái)和多媒體信息網(wǎng)絡(luò)平臺(tái),整合城市全部的信息資源實(shí)現(xiàn)城市社會(huì)經(jīng)濟(jì)等的信息化?!?br>
