DPSIR (Drive Force-Pressure-State-Impact-Response) framework is a kind of simple and effect model to apply to the environmental management. It can supply information on environmental problems in order to enable policy-makers to value their seriousness, support policy development and priority setting by identifying key factors that cause pressure on the environment and monitor the effects of policy responses. This article analysed the cause-effect relationship of the DPSIR model and discussed the linkage between the factors in model and the sphere theory.
