Abstract:
The model of coordinated development of water resources and economy was used to investigate the spatial distribution of coordinated development of water resources and economy in Anhui Province using the data in the normal flow year of 2005. The results showed that the regional difference of the coordinated development degree of water resources and economy is significant between different cities in Anhui province. There were two outstanding types: extremely incoordination with high utilization ratio of water resources (five cities) and coordination with low utilization ratio of water resources (six cities), and other cities showed coordination with moderate utilization ratio of water resources. The five cities (Hefei, Wuhu, Maanshan, Tongling, and Huainan) showing incoordination with high utilization ratio of water resources had the highest per capita GDP , whereas the three cities (Fuyang, Bozhou, and Suzhou) showing coordination with low utilization ratio of water resources had the lowest per capita GDP . Moreover, the three cities (Xuanchen, Chizhou, and Huangshan) showing coordination with low utilization ratio of water resources had the highest per capita water resources. Further, Huaibei and Wuhu had similar population and water resources quantity, but the coordination degree was significantly different, and the differences of GDP and water consumption between the two cities were about 2 to 3 times. Consequently, the different level of socio-economic development and the resulting water consumption difference were the basic causes for the difference of coordinated development between water resources and social economy. Compared with previous studies, the results in this study were in good agreement that the coordination degree and the indicator of socio-economic drought are two main indexes to measure the sustainable development of water resources, especially in the area with a higher economic development level.
