关于我国环境信息系统建设几个问题的思考

用户在规定和修改环境信息系统的目标和功能，在项目设计和开发过程管理等重大问题上比开发者更为重要。系统的用户识别不准确，是我国一些环境信息系统开发出来后无人使用的主要原因。高层次介入、动态介入和投入足够资源等是用户发挥作用不可缺少的方式。系统分析不仅要满足用户的当前需求，而且应帮助用户理顺其信息流渠道，规范其信息搜集方式。环境信息系统的开发应坚持少而精和实事求是订目标的原则，正确把握培训、使用和维护的关系。 

On Some Issues Related to Environmental Information Systems Construction in Chinea

A client is more important than a developer in major issues like specification and modification of goals and functions of an environmental information system,project design and management of development.Inaccuracy in identifying the client of the system is largely responsible for some of the environmental information systems in China that nobody is using after their development.Involvement of high level persons,dynamic involvement and investment of sufficient resources are imperative means for a client to play his or her roles.Systems analysis should not only satisfy current demand of the client but also should assist the client in properly restructuring channels for information flow and means for information collection.Development of an environmental information system should adhere to principles of few and good,establishing goals on realistic ground and correctly handle relations among training,utilization and maintenance.
