基于环境地质问题分区的海峡西岸经济区环境地质图编图研究

Establishment of environmental geological map of economic zone on the west side of the Taiwan Straits based on the division of environmental geological problems

在前人资料的基础上,全面总结了区内1999年地质大调查以来的水工环地质调查的最新成果,以环境地质问题分区作为普染色,运用GIS技术编制了海峡西岸经济区环境地质图,该图件能够反映海峡西岸经济区地质环境特征、地质资源、主要环境地质问题等内容。本文从编图的基本原则、编图范围、主要内容、图面表示方法等方面进行了阐述,研究发现,以环境地质问题分区作为环境地质图主要内容的编图方法,比以往采用环境地质背景分区的方式更能直观地反映区内的环境地质问题,可以更好地为国土资源规划、地质环境保护提供支撑。

Based on the previous data,this paper summarizes the latest achievements of hydrogeological,engineering and environmental geology survey since 1999 geological survey in region,using the geo-environmental problem partition as the general coloring,and GIS technology to compose the environmental geological map of west coast economic zone.The map reflects the economic environment,the geological environment characteristics,geological resources and the main environmental geological problems of the West Side of the Straits.In this paper,with elaborating the basic principles of compilation,the scope of mapping,the main content and the surface representation of the method,we take the environmental geological problems as the main content of environmental zoning of geological map drawing method,instead of using the background of environmental geology way,which can more directly reflect environmental geological problems in the district,and be better for supporting land and resources planning,geological environment protection.
