After a large-scale infrastructure andfunction development in the past decade, it hasbecome "the miniature of modernization constructionin Shanghai" and "the symbol of reform and openingin China". But, due to the rapid urbanization andassociated environmental issues, rivers in the studiedarea remain seriously polluted and are alsodiminishing. Consequently this damages the featuresof the water village and investment setting in thePudong New Area. On the basis of analyzing the aerophotographs (1989, 1994 and 1999) and land usedata by Remote Sensing and Geographic InformationSystem, this paper illustrated that: 1) The river densityof the studied area has declined by 1/3 from 1989to 1999; 2) Since the development and opening oPudong, the river system has experienced twodeclining phases: rapid declining (1989-1994) andslow declining (1994-1999); 3) The fast urbanizationof land-use is a primary threat to the river systemwhich is particularly prominent within the Inner BelWay and in the developed zone of Pudong area.展开更多
