国内外城市环境地质工作进展

Review on urban environmental geologic work in China and abroad

城市化是世界各国发展的共同趋势,是人类文明和进步的标志。论文简述了国内外城市环境地质工作的历史发展,着重论述了城市地质工作的内容,指出我国城市环境地质中存在的问题。如地面沉降、地裂缝、岩溶塌陷等地质灾害及水资源短缺、城市废弃物处置以及特殊岩土环境问题。为了提高城市规划和确保城市可持续发展,仅从以下5个方面提出了我国城市地质工作的方向:(1)城市地质环境条件、地质资源综合调查评价;(2)城市主要环境地质问题调查;(3)城市群、城市密集区环境地质适宜性综合评价;(4)城市环境地质综合研究;(5)城市环境地质信息系统建设。

Urbanization appears a common trend for every country to meet in development, which is the mark of human beings civilization and progress. In this paper, domestic and abroad history of environmental geology development in urban area is briefly introduced, contents of urban environmental geology are detailedly expounded. Problems of urban environmental geology in China, such as land subsidence, ground fissures, karst collapse, water resource shortage, urban waste matter processing, peculiar soil environmental issues etc., are pointed out. In order to improve urban plan and ensure sustainable development in urban, aims of urban geological work in China are as follows:(1)investigating and evaluating of geologic environment condition and geologic resources in urban;(2) investigating of major urban environmental geologic issues;(3) synthetical evaluating of environmental geology applicability in metropolitan area; (4)synthetical researching of urban environmental geology; (5) establishing information systems of urban environmental geology.
