Space-Time Concept-Based Regional Coordination Degree Assessment Model and Its Verification

Focusing on the nature of interregional relationship,the connotation of coordination degree is specified as a quantitative index to determine coordination degree within a system or between systems.On such a basis,proceeding with the coordination degree between the two sub-systems,i.e.socio-economy and resource-environment,indices are screened and an evaluation model built up.The indices and the model are tested in analyzing by phase coordination degree of the development of Xinjiang in the period from 1990 to 2003.Results show that the two sub-systems developed upwards,though in fluctuation,and the coordination degree between the two,on the whole,was gradually getting better.Comparison between the 87 counties and cities of Xinjiang in coordination degree demonstrated that spatial variation was quite notable.
