一变革时代空间信息系统的作用当今许多国家面临的最为严重的一个问题,是经济停滞並时常伴随人口停滞的情况下遭受经济和技术的结构性变动的深刻影响。第二次世界大战以来,重大的经济和技术变革虽非首次出现,然而目前情况较之五、六十年代却有明显的不同特点:(1)当前的变革出现在萧条时期,而不是出现在增长时期;(2)由结构性变动导致的负溢出效应(如分布效应)的意识更加强烈;(3)综合评价这些变动对经济、社会和环境的长期影响的制度化倾向更加强烈。因此,如果信息系统对上述情况未加考虑,那它就只能应用于全然不同的其它场
The Role of Spatial Information Systems in an Era of Change One of the most serious problems facing many countries today is the profound impact that economic stagnation and structural changes in the economy are often accompanied by stagnant populations. Although not the first time since the Second World War, major economic and technological changes have taken place, the current situation is distinctly different from the 1950s and 1960s: (1) The current changes have occurred in depression rather than in (2) the awareness of negative spillover effects (such as distribution effects) caused by structural changes is more intense; (3) the systematic tendency of comprehensively evaluating the long-term economic, social and environmental impacts of these changes is even stronger. Therefore, if the information system does not consider the above situation, it can only be applied to completely different other fields
