Abstract:This paper aimes to establish logic framework for the analysis of planning coordination,which includes three steps,the collection and screening of target plans,then the assessment of planning coordination,and finally the harmonization of the conflicts or inconsistency among plans.And two dimensions should be involved in the analysis process according to the concept of coordination,namely the plan interactivity and plan consistency.A measurable index system is set up to evaluate the level of planning coordination via Delphi approach together with the theoretical study mentioned above.Finally,a case which applies this framework to conducting a planning coordination analysis in the practice of planning environmental impact assessment further demonstrates that the analysis of planning coordination serves not only as an assessment tool,but also an effective mechanism to stress the conflicts among correlative decisionmakings.
