Studies on the Differences of County Economic Development Level and the Water Resources Coordination in Central Yunnan Economic Zone

42 counties in Central Yunnan Economic Zone was regard as research unit in this paper. Principal Component Analysis and the evaluation models of the coordination degree have been used to analyze spatial pattern and time variation characteristics, which include both the county economic development level and the coordination degree of county economic development level and water resource in Central Yunnan Economic Zone. The result shows: (1)From 1999 to 2009, the difference of county economic development level has enlarged as if waves. The spatial structure in this region evolved from pole nucleus type to Pole-axis type gradually. At the same time, The difference of coordination has been gradually enlarged.(2)For the coordinated development of all regions, some measures should be taken such as strengthening the radiation effect of growth poles, optimizing the regional spatial structure and promoting the coordinated development of industrial structure.
