摘　　要：以区域关系的实质为着眼点,将协调度的内涵界定为度量系统之间或系统内部之间协调状况好坏的定量指标,以此为基础,从社会经济和资源环境2个子系统之间的协调性入手,选择指标构建评价模型,对1990—2003年新疆区域发展的协调性进行了阶段性分析,结果表明社会经济子系统及资源环境子系统发展水平在波动中提升,2个子系统之间的协调性整体上在逐步改善;从空间上对新疆87个县市协调性进行了对比分析,结果表明空间差异性较大。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.
